GI-2 GENERAL INFORMATION

GENERAL FUNDAMENTAL PROCEDURES

NOTICES, CAUTIONS AND WARNINGS

As you read through the various procedures, you will en counter Notices, Cautions and Warnings. Each one is there for a specific purpose. Notices give you added infor mation that will assist you in completing a particular proce dure.Cautions prevent you from making an error that could damage the vehicle. Warnings remind you to be especially careful in specific areas where carelessness can cause personal injury.

The following items contain general procedures you should always follow when working on a vehicle:

PROTECTION OF VEHICLE

Always cover fenders, seats, and floor areas before starting work. Operate the engine only in a well-ventilated area to avoid carbon monoxide poisoning.

A WORD ABOUT SAFETY

The following precautions must be followed when jacking up the vehicle:

1.Block the wheels.

2.Use only the specified jacking positions.

3.Support the vehicle with safety stands.

The engine compartment must be clear of tools and people before starting the engine.

PREPARATION OF TOOLS AND MEASURING EQUIPMENT

All necessary tools and measuring equipment should be available before starting any work.

GI-3 GENERAL INFORMATION

SPECIAL SERVICE TOOLS (SST’S)

Use special service tools when they are required. SST’s can be found under "preparation" prior to any procedure requiring them.

REMOVAL OF PARTS

Begin work only after first learning which parts and subassemblies must be removed and disassembled for replacement or repair.

DISASSEMBLY

If the disassembly procedure is complex, requiring many parts to be disassembled, all parts should be disassembled in a way that will not affect their performance or external appearance. Additionally, these parts should be identified so that reassembly can be done easily and efficiently.

INSPECTION OF PARTS

When removed, each part should be carefully inspected for malfunction, deformations, damage, or other problems.

GI-4 GENERAL INFORMATION

ARRANGEMENT OF PARTS

All disassembled parts should be carefully arranged for reassembly. Separate or otherwise identify the parts to be replaced from those that will be reused.

CLEANING PARTS FOR REUSE

All parts that will be reused should be carefully and thoroughly cleaned using appropriate methods.

REASSEMBLY

Standard values, such as torques and certain adjust ments, must be strictly observed in the reassembly of all parts. If removed, the following parts should be replaced with new ones:

1.Oil seals

2.O-rings

3.Cotter pins

4.Gaskets

5.Lock washers

6.Nylon nuts

DEPENDING ON LOCATION:

1.Sealant should be applied or new gaskets installed.

2.Oil should be applied to the moving components of parts.

3.Specified oil or grease should be applied at the appropriate locations (such as oil seals) before reassembly.

GI-5 GENERAL INFORMATION ADJUSTMENTS

Use appropriate gauges and/or testers when making adjustments.

RUBBER PARTS AND TUBING

Prevent gasoline or oil from contacting rubber parts or tubing.

ELECTRICAL TROUBLESHOOTING TOOLS (TEST LIGHT)

The test light, as shown in figure, uses a 12V bulb. The two lead wires should be connected to probes.

The test light is used for simple voltage checks and in checking for short circuits.

CAUTION

When checking the engine control module (ECM), never use a bulb exceeding 3.4W.

ELECTRICAL TROUBLESHOOTING TOOLS (JUMPER WIRE)

The jumper wire is used for testing by shorting across switch terminals ground connections.

CAUTION

Do not connect a jumper wire from the power source line to a body ground. Such a connection may cause damage to harnesses or electronic components.

GI-6 GENERAL INFORMATION

VOLTMETER

The DC voltmeter measures circuit voltage. A voltmeter with a range of 15V or more is used by connecting the positive (+) probe (red lead wire) to the point where voltage is be measured, and the negative (-) probe (black lead wire)to a bodyground.

OHMMETER

The ohmmeter is used to measure the resistance between two points in circuit and also to check for continuity and the diagnosis of short circuits.

CAUTION

Do not attempt to connect the ohmmeter to any circuit in which voltage is applied. Such a con nection may damage the ohmmeter.

ELECTRICAL PARTS

BATTERY CABLE

Before disconnecting connectors or replacing electrical parts, disconnect the negative battery cable.

CONNECTORS(REMOVAL OF CONNECTOR)

1.Never pull on the wiring harness when disconnecting connectors.

2.Connectors can be removed by pressing or pulling lock lever.

GI-7 GENERAL INFORMATION CONNECTORS (LOCKING A CONNECTOR) Listen for a click when locking connectors. This sound indicates that they are securely locked.

CONNECTORS (INSPECTION)

1.When a tester is used to check for continuity or to measure voltage, insert tester probe from wire harness side.

2.Check terminals of waterproof connectors from connector side because they cannot be accessed from harness side.

NOTE • Use a fine wire to prevent damage to the terminal. • Do not damage the terminal when inserting the tester lead. TERMINALS (INSPECTION)

Pull lightly on individual wires to ensure that they are secured in the terminal.

GI-8 GENERAL INFORMATION

REPLACEMENT OF TERMINALS

Use appropriate tools to remove terminal as shown. When installing the terminal, insert it until it locks securely.

FEMALE

Insert a thin piece of metal from the terminal side of the connector, and then, with the terminal locking tab pressed down, pull the terminal out of the connector.

MALE

Follow the same procedure as female-type terminal.

SENSORS, SWITCHES, AND RELAYS

Always handle sensors, switches and relays carefully.

Do not drop them or accidentally strike them against other parts.

WIRING COLOR CODES

Two-color wires are indicated by a two-color code symbol. The first color indicates the base color of the wire; the second color indicates the color of the stripe.

COMPRESSION PRESSURE INSPECTION

NOTE

If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.

1. Start the engine and allow to warm up to operating temperature (about five minutes). Stop the engine.

2. Disconnect the ignition coil connectors and the sparkplug cables (A).

3. Remove the four spark plugs using a 16mm spark plug wrench.

4. Check the cylinder compression pressure.

1) Insert a compression gauge into the spark plug hole.

2) Full open throttle.

3) While cranking the engine, measure the compression pressure.

NOTE Always use a fully charged battery to obtain

engine speed of 250rpm or more.

4) Repeat step (1) through (3) for each cylinder.

NOTE This measurement must be done in as short a

time as possible. Compression pressure: 1,520kPa (15.5kg/cm2, 220psi) / 370 rpm Minimum pressure: 1,373kPa (14.0kg/cm2, 199psi) Difference between each cylinder: 98kPa (1.0kg/cm2, 14psi) or less

5) If the cylinder compression in 1 or more cylinders is low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat step (1) through (3) for cylinders with low compression.

• If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged.

• If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage past the gasket.

5. Reinstall the spark plugs.

6. Connect the ignition coil connectors and the spark plug cables.

3.Upon completion of the test, set the engine speed at idle. Turn off the headlamps, blower motor and the ignition switch.

EE-19 ENGINE ELECTRICAL SYSTEM

OUTPUT CURRENT TEST

This test determines whether or not the alternator gives an output current that is equivalent to the normal output.

PREPARATION

1. Prior to the test, check the following items and correct as necessary. Check the battery installed in the vehicle to ensure that it is good condition. The battery checking method is described in the section "Battery". The battery that is used to test the output current should be one that has been partially discharged. With a fully charged battery, the test may not be con- ducted correctly due to an insufficient load. Check the tension of the alternator drive belt. The belt tension check method is described in the section "Inspect drive belt".

2. Turn off the ignition switch.

3. Disconnect the battery ground cable.

4. Disconnect the alternator output wire from the alter- nator "B" terminal.

5. Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire. Be sure to connect the (-) lead wire of the ammeter to the disconnected output wire.

NOTE

Tighten each connection securely, as a heavy current will flow. Do not rely on clips.

6. Connect a voltmeter (0 to 20V) between the "B" termi- nal and ground. Connect the (+) lead wire to the alter- nator "B" terminal and (-) lead wire to a good ground.

7. Attach an engine tachometer and connect the battery ground cable.

8. Leave the engine hood open.

2.Start the engine and turn on the headlamps.

3.Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500 rpm and read the maximum output current value indicated by the ammeter.

NOTE

After the engine start up, the charging current quickly drops. Therefore, the above operation must be done quickly to read the maximum current value correctly.

RESULT

1.The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good condition, remove the alternator from the vehicle and test it.

Limit value (70A alternator): 49A min.

NOTE

• The nominal output current value is shown on the nameplate affixed to the alternator body.

• The output current value changes with the elec- trical load and the temperature of the alternator itself. Therefore, the nominal output current may not be obtained. If such is the case, keep the headlamps on the cause discharge of the battery, or use the lights of another vehicle to increase the electrical load. The nominal output current may not be obtained if the temperature of the alternator itself or ambient temperature is too high. In such a case, reduce the temperature before testing again.

2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.

3. Disconnect the battery ground cable.

4. Remove the ammeter and voltmeter and the engine tachometer.

5. Connect the alternator output wire to the alternator "B" terminal.

FUEL FILLER CAP DESCRIPTION A ratchet tightening device on the threaded fuel filler cap reduces the chances of incorrect installation, which would seal the fuel filler. After the gasket on the fuel filler cap and the filler neck flange contact each other, the ratchet produces a loud clicking noise indicating the seal has been set.

EC-15 EMISSIONS CONTROL SYSTEM

EXHAUST EMISSION ONTROL SYSTEM C

DESCRIPTION

Exhaust emissions (CO, HC, NOx) are controlled by a combination of engine modifications and the addition of special control components.

Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control sys- tem. These items have been integrated into a highly effective system which controls exhaust emissions while maintain- ing good driveability and fuel economy.

AIR/FUEL MIXTURE CONTROL SYSTEM [MULTIPORT FUEL INJECTION (MFI) SYSTEM]

The MFI system is a system which uses the signals from the heated oxygen sensor to activate and control the in- jector installed in the manifold for each cylinder, thus pre- cisely regulating the air/fuel mixture ratio and reducing emissions.

This in turn allows the engine to produce exhaust gases of the proper composition to permit the use of a three way catalyst. The three way catalyst is designed to convert the three pollutants (1) hydrocarbons (HC), (2) carbon monox- ide (CO), and (3) oxides of nitrogen (NOx) into harmless substances. There are two operating modes in the MFI system.

1. Open Loop air/fuel ratio is controlled by information programmed into the ECM.

2. Closed Loop air/fuel ratio is adjusted by the ECM based on information supplied by the oxygen sensor.

BASIC INSPECTION PROCEDURE

MEASURING CONDITION OF ELECTRONIC PARTS’ RESISTANCE

The measured resistance at high temperature after vehicle running may be high or low. So all resistance must be measured at ambient temperature (20°C, 68°F), unless there is any notice.

NOTE

The measured resistance in except for ambient temperature (20°C, 68°F ) is reference value.

INTERMITTENT PROBLEM INSPECTION PROCEDURE

Sometimes the most difficult case in troubleshooting is when a problem symptom occurs but does not occur again during testing. An example would be if a problem appears only when the vehicle is cold but has not appeared when warm. In this case, technician should thoroughly make out a "CUSTOMER PROBLEM ANALYSIS SHEET" and recreate (simulate) the environment and condition which occurred when the vehicle was having the issue.

1. Clear Diagnostic Trouble Code (DTC).

2. Inspect connector connection, and check terminal for poor connections, loose wires, bent, broken or corroded pins, and then verify that the connectors are always securely fastened.

3. Slightly shake the connector and wiring harness vertically and horizontally.

4. Repair or replace the component that has a problem.

5. Verify that the problem has disappeared with the road test.

• SIMULATING VIBRATION a. Sensors and Actuators

: Slightly vibrate sensors, actuators or relays with finger.

WARNING

Strong vibration may break sensors, actuators or relays

b. Connectors and Harness : Lightly shake the connector and wiring harness

vertically and then horizontally.

• SIMULATING HEAT a. Heat components suspected of causing the malfunction

with a hair dryer or other heat source.

WARNING

• DO NOT heat components to the point where they may be damaged.

• DO NOT heat the ECM directly.

• SIMULATING WATER SPRINKLING a. Sprinkle water onto vehicle to simulate a rainy day or

a high humidity condition.

WARNING

DO NOT sprinkle water directly into the engine compartment or electronic components.

• SIMULATING ELECTRICAL LOAD a. Turn on all electrical systems to simulate excessive

electrical loads (Radios, fans, lights, etc.).

FL-9 FUEL SYSTEM

CONNECTOR INSPECTION PROCEDURE

1. Handling of Connector a. Never pull on the wiring harness when

disconnecting connectors.

b. When removing the connector with a lock, press or pull locking lever.

c. Listen for a click when locking connectors. This sound indicates that they are securely locked.

d. When a tester is used to check for continuity, or to measure voltage, always insert tester probe from wire harness side.

e. Check waterproof connector terminals from the connector side. Waterproof connectors cannot be accessed from harness side.

NOTE

• Use a fine wire to prevent damage to the terminal. • Do not damage the terminal when inserting the tester lead.

2. Checking Point for Connector a. While the connector is connected:

Hold the connector, check connecting condition and locking efficiency.

b. When the connector is disconnected: Check missed terminal, crimped terminal or broken core wire by slightly pulling the wire harness. Visually check for rust, contamination, deformation and bend.

c. Check terminal tightening condition: Insert a spare male terminal into a female terminal, and then check terminal tightening conditions

FL-10 FUEL SYSTEM

d. Pull lightly on individual wires to ensure that each wire is secured in the terminal.

3. Repair Method of Connector Terminal a. Clean the contact points using air gun and / or

shop rag.

NOTE

Never use sand paper when polishing the contact points, otherwise the contact point may be damaged.

b. In case of abnormal contact pressure, replace

the female terminal.

WIRE HARNESS INSPECTION PROCEDURE 1. Before removing the wire harness, check the wire

harness position and crimping in order to restore it correctly.

2. Check whether the wire harness is twisted, pulled or

loosened. 3. Check whether the temperature of the wire harness is

abnormally high. 4. Check whether the wire harness is rotating, moving

or vibrating against the sharp edge of a part. 5. Check the connection between the wire harness and

any installed part. 6. If the covering of wire harness is damaged; secure,

repair or replace the harness.

ELECTRICAL CIRCUIT INSPECTION PROCEDURE

• CHECK OPEN CIRCUIT 1. Procedures for Open Circuit

• Continuity Check • Voltage Check

If an open circuit occurs (as seen in [FIG. 1]), it can be found by performing Step 2 (Continuity Check Method) or Step 3 (Voltage Check Method) as shown below.

2. Continuity Check Method

NOTE

When measuring for resistance, lightly shake the wire harness above and below or from side to side.

Specification (Resistance)

1Ω or less → Normal Circuit

uit 1MΩ or Higher → Open Circ

a. Disconnect connectors (A), (C) and measure resistance between connector (A) and (C) as shown in [FIG. 2].

In [FIG.2.] the measured resistance of line 1 and 2 is higher than 1MΩ and below 1 Ω respectively. Specifically the open circuit is line 1 (Line 2 is normal). To find exact break point, check sub line of line 1 as described in next step.

FL-11 FUEL SYSTEM

b. Disconnect connector (B), and measure for resistance between connector (C) and (B1) and between (B2) and (A) as shown in [FIG. 3].

In this case the measured resistance between connector (C) and (B1) is higher than 1MΩ and the open circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

3. Voltage Check Method a. With each connector still connected, measure the

voltage between the chassis ground and terminal 1of each connectors (A), (B) and (C) as shown in [FIG. 4].

The measured voltage of each connector is 5V, 5V and 0V respectively. So the open circuit is between connector (C) and (B).

• CHECK SHORT CIRCUIT 1. Test Method for Short to Ground Circuit

• Continuity Check with Chassis Ground

If short to ground circuit occurs as shown in [FIG. 5], the broken point can be found by performing below Step 2 (Continuity Check Method with Chassis Ground) as shown below.

2. Continuity Check Method (with Chassis Ground)

NOTE

Lightly shake the wire harness above and below, or from side to side when measuring the resistance.

Specification (Resistance)

1Ω or less → Short to Ground Circuit

1MΩ or Higher → Normal Circuit

a. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis Ground as shown in [FIG. 6].

The measured resistance of line 1 and 2 in this example is below 1 Ω and higher than 1M Ω respectively. Specifically the short to ground circuit is line 1 (Line 2 is normal). To find exact broken point, check the sub line of line 1 as described in the following step.

FL-12 FUEL SYSTEM

b. Disconnect connector (B), and measure the resistance between connector (A) and chassis ground, and between (B1) and chassis ground as shown in [FIG. 7].

The measured resistance between connector (B1) and chassis ground is 1 Ω or less. The short to ground circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

ECM PROBLEM INSPECTION PROCEDURE

1. TEST ECM GROUND CIRCUIT: Measure resistance between ECM and chassis ground using the backside of ECM harness connector as ECM side check point. If the problem is found, repair it.

Specification (Resistance): 1§Ùr less

2. TEST ECM CONNECTOR: Disconnect the ECM connector and visually check the ground terminals on ECM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.

3. If problem is not found in Step 1 and 2, the ECM could be faulty. If so, replace the ECM with a new one, and then check the vehicle again. If the vehicle operates normally then the problem was likely with the ECM.

4. RE-TEST THE ORIGINAL ECM : Install the original ECM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original ECM with a new one. If problem does not occur, this is intermittent problem (Refer to INTERMITTENT PROBLEM PROCEDURE in BASIC INSPECTION PROCEDURE).

SYMPTOM TROUBLESHOOTING GUIDE CHART

FL-14 FUEL SYSTEM

GASOLINE ENGINE C ONTROL SYSTEM DESCRIPTION

If the Gasoline Engine Control system components (sensors, ECM, injector, etc.) fail, interruption to the fuel supply or failure to supply the proper amount of fuel for various engine operating conditions will result. The following situations may be encountered.

1. Engine is hard to start or does not start at all.

2. Unstable idle.

3. Poor drivability.

If any of the above conditions are noted, first perform a routine diagnosis that includes basic engine checks (ignition system malfunction, incorrect engine adjustment, etc.). Then, inspect the Gasoline Engine Control system components with the HI-SCAN (Pro).

NOTE

• Before removing or installing any part, read the diagnostic trouble codes and then disconnect the battery negative (-) terminal. • Before disconnecting the cable from battery terminal, turn the ignition switch to OFF. Removal or connection of the battery cable during engine operation or while the ignition switch is ON could cause damage to the ECM. • The control harnesses between the ECM and heated oxygen sensor are shielded with the shielded ground wires to the body in order to prevent the influence of ignition noises and radio interference. When the shielded wire is faulty, the control harness must be replaced. • When checking the generator for the charging state, do not disconnect the battery ’+’ terminal to prevent the ECM from damage due to the voltage. • When charging the battery with the external charger, disconnect the vehicle side battery terminals to prevent damage to the ECM.

A malfunction indicator lamp illuminates to notify the driver that there is a problem with the vehicle. However, the MIL will go off automatically after 3 subsequent sequential driving cycles without the same malfunction. Immediately after the ignition switch is turned on (ON position - do not start), the MIL will illuminate continuously to indicate that the MIL operates normally.

Faults with the following items will illuminate the MIL. • Catalyst • Fuel system • Mass Air Flow Sensor (MAFS) • Intake Air Temperature Sensor (IATS) • Engine Coolant Temperature Sensor (ECTS) • Throttle Position Sensor (TPS) • Upstream Oxygen Sensor • Upstream Oxygen Sensor Heater • Downstream Oxygen Sensor • Downstream Oxygen Sensor Heater • Injector • Misfire • Crankshaft Position Sensor (CKPS) • Camshaft Position Sensor (CMPS) • Evaporative Emission Control System • Vehicle Speed Sensor (VSS) • Idle Speed Control Actuator (ISCA) • Power Supply • ECM • MT/AT Encoding • Acceleration Sensor • MIL-on Request Signal • Power Stage

NOTE

Refer to "INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES (DTC)" for more information.

[NON-EOBD]

A malfunction indicator lamp illuminates to notify the driver that there is a problem with the vehicle. However, the MIL will go off automatically after 3 subsequent sequential driving cycles without the same malfunction. Immediately after the ignition switch is turned on (ON position - do not start), the MIL will illuminate continuously to indicate that the MIL operates normally.

Faults with the following items will illuminate the MIL • Heated oxygen sensor (HO2S)

• Mass Air Flow sensor (MAFS) • Throttle position sensor (TPS) • Engine coolant temperature sensor (ECTS) • Idle

speed control actuator (ISCA) • Injectors • ECM

NOTE

Refer to "INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES (DTC)" for more information.

[INSPECTION]

1. After turning ON the ignition key, ensure that the light illuminates for about 5 seconds and then goes out.

2. If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.

SELF-DIAGNOSIS

The ECM monitors the input/output signals (some signals at all times and the others under specified conditions). When the ECM detects an irregularity, it records the diagnostic trouble code, and outputs the signal to the Data Link connector. The diagnosis results can be read with the MIL or HI-SCAN (Pro). Diagnostic Trouble Codes (DTC) will remain in the ECM as long as battery power is maintained. The diagnostic trouble codes will, however, be erased when the battery terminal or ECM connector is disconnected, or by the HI-SCAN (Pro).

NOTE

If a sensor connector is disconnected with the ignition switch turned on, the diagnostic trouble code (DTC) is recorded. In this case, disconnect the battery negative terminal (-) for 15 seconds or more, and the diagnosis memory will be erased.

FL-16 FUEL SYSTEM

THE RELATION BETWEEN DTC AND DRIVING PATTERN IN EOBD SYSTEM

1. When the same malfunction is detected and maintained during two sequential driving cycles, the MIL will automatically illuminate.

2. The MIL will go off automatically if no fault is detected after 3 sequential driving cycles.

3. A Diagnostic Trouble Code(DTC) is recorded in ECM memory when a malfunction is detected after two sequential driving cycles. The MIL will illuminate when the malfunction is detected on the second driving cycle. If a misfire is detected, a DTC will be recorded, and the MIL will illuminate, immediately after a fault is first detected.

4. A Diagnostic Trouble Code (DTC) will automatically erase from ECM memory if the same malfunction is not detected for 40 driving cycles.

NOTE

• A "warm-up cycle" means sufficient vehicle operation such that the coolant temperature has risen by at least 40 degrees Fahrenheit from engine starting and reaches a minimum temperature of 160 degrees Fahrenheit. • A "driving cycle" consists of engine startup, vehicle operation beyond the beginning of closed loop operation.

TROUBLESHOOTING FOR DTC

DTC P0030 O2 Sensor Heater - Heater Control Circuit (Bank1/Sensor1)

COMPONENT LOCATION

DESCRIPTION

In order to control the emission of the CO, HC and NOx components of the exhaust gas, a heated oxygen sensor (HO2S), mounted on the front side and rear side of the catalytic converter, detects the oxygen content in the exhaust gas. The front HO2S signal is used to control air/fuel ratio (closed loop fuel control) and the rear HO2S signal is used to monitor front HO2S and catalyst for proper operation. The HO2S requires a minimum temperature to operate properly and provide a closed loop fuel control system. So the HO2S contains a heater element to reduce warm-up time and ensure proper performance during all driving conditions, which allows for closed loop fuel control or catalyst monitoring immediately upon engine start-up. The ECM controls this heater element by duty cycle. The main relay supplies voltage to the heater and the ECM provides a ground circuit for activating the heater.

FL-32 FUEL SYSTEM

DTC DETECTING CONDITION

1. DTC Description The ECM determines front HO2S heater fault and sets DTC P0030 if the front HO2S heater control driver inside the ECM fails or HO2S is not operational after an elapse of predetermined time since engine start or front HO2S tip temperature is out of normal working range. The ECM illuminates the MIL on the second consecutive driving cycle that the diagnostic runs and fails. 2. Conditions for Setting the DTC

DESCRIPTION

The Intake Air Temperature Sensor (IATS) is installed into the Manifold Absolute Pressure (MAP) sensor. The IATS uses a thermistor whose resistance changes with the temperature. The electrical resistance of the IATS decreases as the temperature increases, and increases as the temperature decreases. The 5 V power source in the ECM is supplied to the IATS via a resistor in the ECM. That is, the resistor in the ECM and the thermistor in the IATS are connected in series. When the resistance value of the thermistor in IATS changes according to the intake air temperature, the signal voltage also changes. Using this signal, the information of the intake air temperature, the ECM corrects basic fuel injection duration and ignition timing.

COMPONENT LOCATION

DESCRIPTION

The Engine Coolant Temperature Sensor (ECTS) is located in the engine coolant passage near the cylinder head for detecting the engine coolant temperature. The ECTS uses a thermistor whose resistance changes with the temperature. The electrical resistance of the ECTS decreases as the temperature increases, and increases as the temperature decreases. The reference 5 V in the ECM is supplied to the ECTS via a resistor in the ECM. That is, the resistor in the ECM and the thermistor in the ECTS are connected in series. When the resistance value of the thermistor in the ECTS changes according to the engine coolant temperature, the output voltage also changes. During cold engine operation the ECM increases the fuel injection duration and controls the ignition timing using the information of engine coolant temperature to avoid engine stalling and improve drivability.

DTC P0121 Throttle/Pedal Position Circuit Range / Performance Problem

COMPONENT LOCATION

DESCRIPTION

The Throttle Position Sensor (TPS) is mounted on the throttle body and detects the opening angle of the throttle plate. The TPS has a variable resistor (potentiometer) who’s characteristic is the resistance changing according to the throttle angle. During acceleration, the TPS resistance between the reference 5V and the signal terminal decreases and output voltage increases; during deceleration, the TPS resistance increases and TPS output voltage decreases. The ECM supplies a reference 5V to the TPS and the output voltage increases directly with the opening of the throttle valve. The TPS output voltage will vary from 0.2~0.8V at closed throttle to 4.3~4.8V at wide-open throttle. The ECM determines operating conditions such as idle (closed throttle), part load, acceleration/deceleration, and wide-open throttle from the TPS. Also The ECM uses the Mass Air Flow Sensor (MAFS) or Manifold Absolute Pressure Sensor (MAPS) signal along with the TPS signal to adjust fuel injection duration and ignition timing.

COMPONENT LOCATION

DESCRIPTION

The heated oxygen sensor is mounted or the front side of Catalytic Converter (warm-up catalytic converter) or in the front exhaust pipe, which detects the oxygen concentration in the exhaust gas. The heated oxygen sensor (HO2S) produces a voltage that varies between 0V and 1V. When the air/fuel ratio is lean, the oxygen concentration in the exhaust gas increases and the front HO2S outputs a low voltage (approximately 0 ~ 0.1 V). When the air/fuel ratio is rich, the oxygen concentration in the exhaust gas decreases and the front HO2S output a high voltage (approximately 0.8 ~ 1 V). The ECM constantly monitors the HO2S and increases or decreases the fuel injection duration by using the HO2S signal, which is called closed-loop fuel control operation.

DTC

P0304 Cylinder 4 - Misfire Detected

DESCRIPTION

Misfires can be caused by lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or many other causes. Even a small number of misfires may result in excessive exhaust emissions due to the unburned mixture. Increased misfire rates cause damage to the catalytic converter. The ECM monitors the crankshaft speed variation to determine if any misfiring generated. The ECM identifies the specific cylinder in which the misfire has occurred and counts individual misfire events by monitoring changes in the crankshaft rotation for each cylinder. A random misfire indicates two or more cylinders are misfiring.

DTC DETECTING CONDITION

1. DTC Description The ECM must monitor the engine for misfiring possibly caused by ignition coil defects or injector fails. If misfiring is detected, the ECM identify the cylinder(s) that has (have) misfired and calculate misfiring rate for a given duration. The DTC for Misfire (P0301 to 0304) is set as soon as misfiring rate exceed the limit which result in damage to the catalyst or increase emissions. The ECM stores individual DTC for the cylinder which has more than 4% of total misfire rate. With more than two cylinders misfire detection, the ECM sets P0300. If the misfire rate is not extremely high, the MIL will be illuminated in the next driving cycle that diagnostic runs and fails. With extremely high misfire rate which has a danger of burning up the catalyst, the MIL blinks immediately. 2. Conditions for Setting the DTC

DTC P0325 Knock Sensor 1 Circuit Malfunction

COMPONENT LOCATION

DESCRIPTION

Knocking is a phenomenon characterized by undesirable vibration and noise and can cause engine damage. The knock sensor (KS) is attached to the cylinder block and senses engine knocking. A knocking vibration from the cylinder block is applied as pressure to the piezoelectric element. The knock sensor (KS) detects vibration upon increase and decrease in engine RPM and generates a voltage based on this vibration. The ECM controls the ignition timing based on the amplitude and frequency of the knock sensor signal. For example, if engine knocking occurs, the ignition timing is retarded to suppress it. This DTC is set when the frequency goes outside a calibrated level.

FL-129 FUEL SYSTEM

DTC DETECTING CONDITION

DTC P0335 Crankshaft Position Sensor Circuit Malfunction

COMPONENT LOCATION

DESCRIPTION

The Crankshaft Position Sensor (CKPS) is a hall effect type sensor that generates voltage using a sensor and a target wheel mounted on the crankshaft; there are 28 slots in the target wheel where one is longer than the others. When the slot in the wheel aligns with the sensor, the sensor voltage outputs low. When the metal (tooth) in the wheel aligns with the sensor, the sensor voltage output is high. During one crankshaft rotation there are 28 rectangular signals and one longer signal. The ECM calculates engine RPM by using the sensor’s signal and controls the injection duration and the ignition timing. Using the signal differences caused by the longer slot, the ECM identifies which cylinder is at top dead center.

DTC P0420 Catalyst System Efficiency Below Threshold (Bank 1)

DESCRIPTION

The ECM uses dual oxygen sensors to monitor the efficiency of the manifold catalytic converter (warm-up catalytic converter). By monitoring the oxygen storage capacity of a catalyst, its efficiency can be indirectly calculated. The upstream (front) HO2S is used to detect the amount of oxygen in the exhaust gas before it enters the catalytic converter. A low voltage indicates high oxygen contents (lean air mixture). A high voltage indicates low oxygen contents (rich air mixture). When the catalyst efficiency drops, no chemical reaction takes place. This means the concentration of oxygen will be the same at the rear as it is at the front. The output voltage of the rear HO2S copies the voltage of the front HO2S.To monitor the system, the lean-to-rich switches of the front HO2S to the rear HO2S is counted. The ratio of rear switches to front switches is used to determine whether the catalyst is operating properly. An effective catalyst will have fewer rear switches than front switches, that is, a ratio closer to zero.

DTC DETECTING CONDITION

1. DTC Description The ECM calculates oscillation size of rear HO2S signal which represents catalyst conversion properties. This oscillation size will determine if catalyst conversion is low due to aging or poisoning from leaded fuel or misfiring. The ECM sets P0420 if the average of calculated oscillation size of rear HO2S signal during predetermined duration is higher than the predetermined threshold. If same error code is set in the next driving cycle, the ECM illuminates the MIL. 2. Conditions for Setting the DTC

DTC P2096 Fuel Trim Malfunction - System Too Lean (Downstream)

COMPONENT LOCATION

DESCRIPTION

In order to provide the best possible combination of drivability, fuel economy, and emission control, the ECM uses a closed loop air/fuel metering system. The ECM monitors the HO2S signal voltage and adjusts the fuel delivery based on the HO2S signal voltage in closed loop fuel control. Changes in fuel delivery will be indicated by the short-term and the long-term fuel trim values. The ideal fuel trim value is around 0%. The ECM will add fuel when the HO2S signal is indicating a lean condition. Additional fuel is indicated by fuel trim values that are above 0%. The ECM will reduce fuel when the HO2S signal is indicating a rich condition. Reduction in fuel is indicated by fuel trim values that are below 0%. The DTC relevant to fuel trim will be set when the value reaches excessive levels because of a lean or rich condition.

DTC DETECTING CONDITION 1. DTC Description The ECM monitors the trim of lambda control by the rear HO2S signal in addition to the HO2S monitoring. The trim value calculation is based on the difference of rear HO2S signal from desired value. The ECM sets DTC P2096 if either trim value or the difference of rear HO2S from desired value is reached to the maximum threshold.

This newly developed automatic transaxle is a light andcompact transaxle for FF type small vehicles and providessmooth operation, swift driving, and improved fuel con-sumption. Its electronically-controlled shift point and shiftoil pressure have resulted in delicate gear change controlfor various driving factors such as throttle position and ve-hicle speed. Thus, smooth driving at all speeds has beenrealized.A symmetrical three-element, single-stage, two-phasetorque converter is employed. The transaxle consists of2 single planetary gears, 3 sets of disc clutches, 1 setof disc brakes, 1 set of band brakes, 1 set of one-wayclutches, etc.The number of planetary gears, one-way clutches, anddisc brakes is 1 set fewer than the conventional transaxle,which improves efficiency.

POWERFLOW MECHANISM

Planetary gear unit

Planetary gear unit shifts the gear position to forward, re-verse, or neutral while driving.

The unit consists of a sun gear, a planetary carrier, and aninternal gear.The different engagement patterns of this unit installed inthe front and rear operate when driving forward, backward,and shifting.

LKHE002B

AT -12 AUTOMATIC TRANSAXLE SYSTEM

Clutches and brakes

To shift gears via the planetary gear unit, clutches andbrakes are used to engage and lock the components ofthe front and the rear.

Clutches and brakes, except the one-way clutch, are op-erated by oil pressure switched by the valve body, the shiftvalve, and the solenoid valve.

[OPERATING CONDITIONS]

LKHE002C

Low clutch

The low clutch causes an engagement between the rearinternal gear and the front planetary carrier.

Low & reverse brake

The low & reverse brake locks the front planetary carrierwhen the vehicle is moving backward. In other cases, thebrake operates in 1st gear in the "L" range with the lowclutch in order to lock the rear internal gear. It operates toobtain engine brake in the "L" range.

High clutch

The high clutch causes an engagement between the frontplanetary carrier and the input shaft. It operates in 3rd and4th gears.

Reverse clutch

The reverse clutch causes an engagement between thefront sun gear and the input shaft. It operates with the low& reverse brake when the vehicle is moving backward.

Low one-way clutch

The low one-way clutch prevents reverse rotation of thefront carrier and the rear internal gear with low clutch.It operates mechanically without being operated by oilpressure.When the front carrier and the rear internal gear with lowclutch rotate clockwise, even if engine brake is desirable,engine brake does not occur.

AUTOMATIC TRANSAXLE SYSTEM AT -13

2-4 brake and brake servo

The 2-4 brake and brake servo lock the front sun gear.They operate in 2nd and 4th gears.Operation is via the 2-4 brake servo. Line pressure is ap-plied to the engagement and release sides.The brake operates when line pressure is applied to theengagement side only.

The 2-4 brake does not operate when line pressure is ap-plied to both the engagement and release sides.

Lock-up clutch

The lock-up clutch is employed inside the torque converterto lock up when creation conditions are met in 3rd and 4thgears.

LKHE002E

AUTOMATIC TRANSAXLE SYSTEM AT -15

1ST GEAR ("D" AND "2" RANGES)

The operational clutch, input and output, and rotating con-ditions of each gear and carrier are almost the same asthose in the "L" range. However, since the low & reversebrake is not operating, the rear internal gear is locked only

against counterclockwise rotation by the one-way clutch,and can rotate clockwise.Even if engine brake is desirable, the rear internal gear isallowed to rotate clockwise. Therefore, engine brake doesnot occur.

LKHE002F

AT -16 AUTOMATIC TRANSAXLE SYSTEM

2ND GEAR

ns > nc indicates that output rotation has been reducedcompared to input rotation.In 1st gear operation, the front carrier is locked and thefront sun gear rotates counterclockwise. However, in 2nd

gear operation, the front sun gear is locked and the frontcarrier rotates clockwise. Therefore, the front internal gearrotates faster than in 1st gear, and output rotation in 2ndgear becomes faster than the rotation in 1st gear.

LKHE002G

AUTOMATIC TRANSAXLE SYSTEM AT -17

3RD GEAR

In 3rd gear, the rotations of the rear sun gear and the rearinternal gear are the same, which means the rear plane-tary unit rotates as a unit and ns=ni=nc. Therefore, theinput and output axes are linked directly.

LKHE002H

AT -18 AUTOMATIC TRANSAXLE SYSTEM

4TH GEAR

In 4th gear, the front sun gear is locked and the front car-rier rotates. The front internal gear rotates faster than thefront carrier. Therefore, output rotation is faster than inputrotation.

LKHE002I

AUTOMATIC TRANSAXLE SYSTEM AT -19

REVERSE

In the "R" range, the front carrier is locked and the frontsun gear rotates clockwise. The front internal gear rotatescounterclockwise. Therefore, the output axis rotates coun-terclockwise, and the vehicle moves backward.

OIL PRESSURE MECHANISM

VALVE BODY

The valve body delivers oil pump discharge pressure tothe clutches and brakes.

The valve body consists of a manual valve which deliversbasic oil pressure, shift valves which switch the oil pres-sure circuit to the clutches and brakes, a pressure regula-tor valve which regulates line pressure, and accumulatorswhich practice smooth shift shock.In the valve body, there are oil circuits. Shift valves areoperated by the shift solenoid valves.

Valve name FunctionPressure regulator valve Regulates oil pump discharge pressure to the set pressure.

Manual valve Delivers line pressure directory by select lever.

Pilot valve Holds oil pressure steady which fluctuates accordingto driving conditions.

Pressure modifier valve Regulates pilot pressure applied to pressure regulator valve.

Line pressure solenoid valve Regulates pilot pressure applied to pressure modifier valve.

Line pressure relief valve Prevents line pressure applied to manual valve fromincreasing above the allowable value.

Shift valve A Switches line pressure applied to shift valve B and theengagement side of 2-4 brake servo.

Shift valve B Switches line pressure applied to each of the clutch and brake.

Shift solenoid valve A Operates shift valve A.

Shift solenoid valve B Operates shift valve B.

Servo release timing valve Adjusts timing to switch the release side of 2-4 brakeservo to low clutch or high clutch.

Accumulator control valve Regulates line pressure applied to each accumulator.

Lock-up control valve Regulates oil pressure applied to both engagement andrelease sides of lock-up clutch.

Lock-up solenoid Regulates pilot pressure applied to lock-up control valve.

VALVES AND SOLENOIDS

Pressure regulator valve

The pressure regulator valve regulates the oil pump dis-charge pressure to the set pressure.AT fluid for which oil pressure has been regulated lubri-cates the rotating parts, the torque converter and the in-side of the valve.The oil pressure changes in response to the driving rangeand throttle position.

Manual valve

The manual valve delivers the line pressure directly via theselect lever. LKHE002L

AUTOMATIC TRANSAXLE SYSTEM AT -21

Pilot valve

The pilot valve holds the oil pressure steady which fluctu-ates according to driving conditions.The oil pressure which has passed through this valve iscalled the pilot pressure. It is delivered through each ofthe solenoid valves to the operation side of the shift valvesand the pressure modifier valve.

Pressure modifier valve

The pressure modifier valve is operated via pilot pressurewhich is itself regulated by the line pressure solenoid valve.The oil pressure which has passed through this valve iscalled the modifier pressure. The modifier pressure op-erates the pressure regulator valve and the accumulatorcontrol valve. Thus, the line pressure changes in responseto driving conditions.

LKHE002M

Shift valve A

Lock-up control

When conditions are met when driving at higher than acertain speed in 3rd (overdrive OFF) or 4th (overdrive ON)gears, the AT controller outputs a signal to the lock-up so-lenoid and locks up the lock-up clutch in the torque con-verter. This is the lock-up control.Lock-up control is operated by the lock-up solenoid andthe lock-up control valve.

Lock-up control execution conditions1. The shift position must be 3rd or 4th gear.2. The throttle opening angle and vehicle speed must be

within the lock-up control range.3. The AT fluid temperature must be within the control

execution range. [20 C(68 F) or more]4. The shift switch is in the "D" position.

TROUBLESHOOTING ECB43DF8

When carrying out troubleshooting of the automatic trans-mission, check the transmission in the vehicle first to findtheroot of the problem, and then determine whether thetransmission should be disassembled or not.Disassembling the transmission without finding the root ofthe problem will result in wasted time and may cause sec-ondary problems.Automatic transmission problems are categorized as fol-lows.

1. Improper inspection or adjustment

2. Poor engine performance

3. Failure of hydraulic control mechanism

4. Failure of electric control unit

5. Mechanical failure in transmission

In order to properly diagnose the problem in the vehicle, tryto determine as accurately as possible from the customerthe nature of the problem. Try to reproduce the problem ifpossible.

DIAGNOSTICS TROUBLESHOOTING

The AT system is equipped with a diagnostic function,which is an important key in electrical troubleshooting. Asfor mechanical problems, if no error codes are detectedby this function, check and troubleshooting should becarried out referring to the "Troubleshooting according totrouble symptoms".

LKHE004M

AT -50 AUTOMATIC TRANSAXLE SYSTEM

Technical interview

The first step in the troubleshooting procedure is to as-sess the conditions which prevailed at the time the prob-lem occurred and to decide on a course of action on thebasis of these factors. It is easy to assess the conditionswhen it continues at the acceptance. However, when theproblem disappears, it is difficult. If the problem can bereproduced, actioncan be taken immediately. If not, everyeffort should be taken to reproduce the problem as closelyas possible before proceeding. Even experience servicepersonnel may make errors or come to a standstill if trou-bleshooting is carried out without first trying to accuratelyreproduce the problem. For example, a problem which oc-curs only in cold weather or because of vibrations from theroad surface can not be accurately reproduced when theengine is warm or when the vehicle isat a stop. Therefore,to reproduce the problem, it is important that the customershould be asked for detailed circumstances which lead tothe problem: this is the "technical interview".As the information gathered in the course of this interviewis discussed in troubleshooting, it is necessary not onlytoask a series of questions but also to suggest what fac-tors may have had a bearing on the problem. It may behelpful to create a check-list which could be used in suchinterviews.

Primary check

It is necessary to check whether or not the basic automatictransmission maintenance has been carried out.The maintenance details are outlined in the "Primarycheck" and "Maintenance".

1. Power supply and voltage checkThe battery voltage must be 10 - 14V when the engineis stopped.

2. AT fluid checkCheck level and AT fluid condition.

3. Stall testCheck the engine speed at stall in each range, andcheck the overall performance of the automatic trans-mission and the engine.

4. Oil pressure testMeasure the line pressure when idling and when theengine has stalled, and check the functions of eachcomponent.

5. Ignition timing and idling engine speed checkAdjust these if they are not within the specified ranges.If a problem occurs such as a "fluctuating enginespeed", troubleshoot the engine first.

6. Select linkage check and adjustment

7. Throttle sensor check and adjustment

8. Road testA road test is carried out to assess the problem prop-erly and as a post maintenance check.

9. Electrical wiring checkCheck that the connectors fit securely, that the con-nector has neither become rusty nor accumulatedgrime, that the terminals are secure and have notbecome distorted and that no parts have come intocontact with rotating, shaking or hot parts and havenot become loose or damaged.

Factors relating to the problem

When troubleshooting, the service technician mustendeavor to reproduce the problem. It is important,therefore, to try,on the basis of the technical interview,to reproduce the set of circumstances which lead to theproblem (road, climateand driving conditions) initially.A patient approach to achieving this end, reproducingfactors such as vibration (by manually moving the wireharness or relay), by creating heat (applying hot air) andby using water, is necessary.Therefore, presuming that the assembly/parts may be thecause of the problem and using a tester to check the vari-ous contributory factors will make it possible to determinethe behavior of the assembly/parts at the time the problemoccurred.

PRIMARY CHECK

Be sure to carry out this check before carrying out anyother.Do not replace, add to or adjust the level of the AT fluidbefore carrying out the reproducing test of the problem.

AT FLUID LEVEL AND CONDITION

1. Drive the vehicle until the ATF reaches normal tem-perature [70-80 C(158-176 F)]. This temperature willbe reached after approximately 5 km of urban driving.

2. Park the vehicle on level ground and apply the parkingbrake while the engine is idling. Move the select leverslowly from "P" to "L" and then move it back to "P".

3. While the engine is running, pull out the oil levelgauge, wipe it clean with a paper towel and insert it tocheck the AT fluid level. The level of the fluid shouldbe within the range specified on the level gauge. Ifthe level is too low, add the recommended AT fluid.Check the AT fluid for abnormal smell, foreign matter,or discoloration.

NOTE- The fluid level changes before and after the en-

gine is warmed up. Be sure to follow the proce-dure above when carrying out this check.

DISASSEMBLY E4F88A33

PRECAUTIONS WHEN DISASSEMBLING ANDRE-ASSEMBLING TRANSMISSIONS

Because automatic transmissions consist of precisionparts, pay attention to the following during assembly anddisassembly.

• Carry out disassembly in a clean, dust-free location.• Place a rubber mat on the bench; be careful not to

scratch the parts.• Do not use gloves or wastes. (Use nylon cloth or

paper towels.)• When disassembling the case connecting section,

do not force anything with a screwdriver or similartool; gently knock the parts of the case with a rub-ber-headed hammer to remove them.

• Before disassembling, clean the external of the trans-mission. (To prevent any contamination from enteringthe transmission)

• Clean the disassembled parts with AT fluid orkerosene, and check the oil passages by blowing air.(Be careful not to allow the AT fluid or kerosene tosplash or spill.) Clean the disk, brake band, resinwasher and rubber parts using the AT fluid.

• Replace the gasket, oil seal, and the "O" and "D" ringswith new ones.

• Apply the AT fluid to the sliding and rotating sectionsbefore re-assembly.

• Use new disc and brake band after soaking them inAT fluid for more than two hours.

• Do not use the oils other than those specified.

INSPECTION PROCEDURE

When carrying out maintenance of the automatic trans-mission, check the transmission in the vehicle first to findthe root of the problem, and then determine whether thetransmission should be disassembled or not.Disassembling the transmission without finding the root ofthe problem will result in wasted time and may cause sec-ondary problems.Automatic transmission problems are categorized as fol-lows:

1. Improper inspection or adjustment

2. Poor engine performance

3. Failure of hydraulic control mechanism

4. Failure of electric control unit

5. Mechanical failure in transmission

In order to properly diagnose the problem in the vehicle, tryto determine as accurately as possible from the customerthe nature of the problem. Try to reproduce the problem ifpossible.

NUTS AND BOLTS

METRIC THREAD

Vehicle dimensions are generally specified in metric units.Metric threads are used for most of the parts. These arealmost the same size as inch threads. Therefore, whenreplacing screws, be sure to use screws of proper nominaldiameter, pitch and strength.

Identification of screw strength

Generally, the strength of metric threads is categorized as"4T" and "7T". This can be identified by the mark curvedon the bolt head. "T" indicates the tensile strength.When replacing metric threads, use the screws of thespecified strength or stronger (that is, with the samestrength number or larger). It is also important to use theproper size screws.The general sizes and pitches (not including exceptions)are as shown in the table.

GENERAL GENERAL TROUBLESHOOTING INFORMATION

BEFORE TROUBLESHOOTING 1.Check applicable fuses in the appropriate fuse/relay

box. 2.Check the battery for damage, state of charge, and

clean and tight connections.

NOTE

• Do not quick-charge a battery unless the battery ground cable has been disconnected; otherwise you will damage the alternator diodes.

• Do not attempt to crank the engine with the bat tery ground cable loosely connected or you will severely damage the wiring.

3.Check the alternator belt tension.

HANDLING CONNECTORS 1.Make sure the connectors are clean and have no

loose wire terminals. 2.Make sure multiple cavity connectors are packed with

grease (except watertight connectors). 3.All connectors have push-down release type locks

(A).

4.Some connectors have a clip on their side used to attach them to a mount bracket on the body or on another component. This clip has a pull type lock.

5. Some mounted connectors cannot be disconnected unless you first release the lock and remove the con- nector from its mount bracket.

6.Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.

7.Always reinstall plastic covers.

8.Before connecting connectors, make sure the terminals (A) are in place and not bent.

BE-3 BODY ELECTRICAL SYSTEM

9.Check for loose retainer (A) and rubber seals (B). HANDLING WIRES AND HARNESSES

1.Secure wires and wire harnesses to the frame with their respective wire ties at the designated locations.

2.Remove clips carefully; don’t damage their locks (A).

10.The backs of some connectors are packed with grease. Add grease if necessary. If the grease (A) is contaminated, replace it.

3.Slip pliers (A) under the clip base and through the hole at an angle, then squeeze the expansion tabs to release the clip.

11.Insert the connector all the way and make sure it is securely locked.

12.Position wires so that the open end of the cover faces I

down. 4.After installing harness clips, make sure the harness doesn’t interfere with any moving parts.

5.Keep wire harnesses away from exhaust pipes and other hot parts, from sharp edges of brackets and holes, and from exposed screws and bolts.

BE-4 BODY ELECTRICAL SYSTEM 6.Seat grommets in their grooves properly (A). Do not

leave grommets distorted (B).

TESTING AND REPAIRS

1. Do not use wires or harnesses with broken insulation. Replace them or repair them by wrapping the break with electrical tape.

2. After installing parts, make sure that no wires are pinched under them.

3. When using electrical test equipment, follow the man ufacturer’s instructions and those described in this manual.

4. If possible, insert the probe of the tester from the wire side (except waterproof connector).

5.Use a probe with a tapered tip.

FIVE-STEP TROUBLESHOOTING

1. Verify the complaint Turn on all the components in the problem circuit to verify the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area.

2. Analyze the schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power feed through the circuit components to ground. If several circuits fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit operation, identify one or more possible causes of the problem.

3. Isolate the problem by testing the circuit Make circuit tests to check the diagnosis you made in Step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible.

4. Fix the problem Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures.

5. Make sure the circuit works Turn on all components in the repaired circuit in all modes to make sure you’ve fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on the fuse. Make sure no new problems turn up and the original problem does not recur.
