Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Forinformation about these practices, REFER to: (100-00 General Information, Description and Operation) . Diagnostic Methods

Network Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of intermittent concerns such as damagedwiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming,often set network Diagnostic Trouble Codes (DTCs). Replacing a module to resolve a network DTC is unlikely toresolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Testthe vehicle battery. REFER to: (414-01 Battery, Mounting and Cables, Diagnosis and Testing) . Battery

Normal Operation and Fault Conditions

Voltage is provided to the A/C clutch relay coil. When A/C is requested and A/C line pressures allow, a ground isprovided to the A/C clutch relay coil from the PCM , energizing the A/C clutch relay.





P0645 A/C Clutch Relay Control Circuit The DTC sets when the PCMgrounds the relay circuit and morevoltage than expected is detectedon the relay circuit. The DTC alsosets when the relay circuit is off andno voltage is detected on the relaycircuit.

The Air Inlet Door Is Inoperative



To rotate the air inlet door actuator, the FCIM supplies voltage and ground to the air inlet door actuator through thedoor actuator motor circuits. To reverse the air inlet door actuator rotation, the FCIM reverses the voltage andground circuits. The air inlet door actuator feedback resistors are supplied a ground from the FCIM by the air inlet



door actuator return circuits and a 5-volt reference voltage on the air inlet door actuator reference circuits. The FCIMreads the voltage on the air inlet door actuator feedback circuits to determine the air inlet door actuator position bythe position of the actuator feedback wiper arm.resistor

During an actuator calibration cycle, the FCIM drives the air inlet door until the door reaches both internal stops inthe FCIM case. If the air inlet is temporarily obstructed or binding during a calibration cycle, the FCIMmay interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands theactuator to its end of travel, the air intake may not be from the expected source.

The Temperature Control Is Inoperative Or Does Not Operate Correctly



Temperature Door Actuator, REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) (412-00 ClimateControl System - General Information) .

During an actuator calibration cycle, the module drives the temperature door until the door reaches both internalstops in the HVAC case. If the temperature door is temporarily obstructed or binding during a calibration cycle, themodule may interpret this as the actual end of travel for the door. When this condition occurs and the modulecommands the actuator to its end of travel, the airflow may not be the expected temperature.




NOTE: The manual climate control system has one temperature door actuator and it is located on the passengerside of the Heating, Ventilation and air conditioning (HVAC) case. For this temperature door actuator, the DiagnosticTrouble Codes (DTCs) referenced by the Front Controls Interface Module (FCIM) set the driver side temperature doorDiagnostic Trouble Codes (DTCs). The wiring circuits and connectors for the temperature door actuator utilize thedriver side temperature door actuator inputs to the Front Controls Interface Module (FCIM).

P6 CHECK THE ENGINE COOLANT LEVELNOTE: Allow the engine to cool before checking the engine coolant level.

Visually inspect the engine coolant level at the degas bottle.

Is the engine coolant level within specifications?

Yes GO to P7

NoREFER to: Engine Cooling (303-03 Engine Cooling - 1.6L EcoBoost (132kW/180PS) - Sigma) .

P7 CLEAR ALL PCM (POWERTRAIN CONTROL MODULE) DIAGNOSTIC TROUBLE CODES



Connect all disconnected connectors. Make sure they seat and latch correctly.

Ignition ON.

Using a diagnostic scan tool, CLEAR all PCM Diagnostic Trouble Codes (DTCs).

Start the vehicle andallow engine to reach normal operating temperatures.

NOTE: The engine must be auto-stopped to request the cabin heater coolant pump on. Further informationcan be found in the Owner's Literature for full Auto Start-Stop enabling/disabling.

Using the HVAC controls, select panel mode, set temperature to full hot and set blower speed to low.

Drive the vehicle above 3 mph (4 km/h).

Stop the vehicle on a level surface.

Make sure that the steering wheel is set to the straight ahead position.

Keep the transmission selector lever in position D, brake pedal pressed and doors closed.


Monitor the PCM coolant pump status (COOLPMP_A_STAT) PID for at least 1 minute.

Does the cabin coolant pump turn on?

Yes If the cabin coolant pump runs for 10 seconds on and 10 seconds off, PURGE the air fromthe coolant system. REFER to: (303-03A Engine Cooling - 1.5L EcoBoost (118kW/160PS), General Procedures) . REFER to: Cooling System Draining and Vacuum Filling (303-03 Engine Cooling - 1.6LEcoBoost (132kW/180PS) - Sigma) .

If the cabin coolant pump runs normally, the system is operating correctly at this time. Theconcern may have been caused by pump connections. ADDRESS the root cause of anyconnector or pin issues.

No INSTALL a new cabin heater coolant pump. For 1.5L, REFER to: (412-00 Climate Control System - General Information, Removal and Installation) .

If the concern is still present, GO to P8

P8 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION



Ignition OFF.








P06A0



The externally controlled variable displacement compressor is electronically controlled by the PCM . The PCM pulsewidth modulates the ground to the externally controlled variable displacement compressor to change thedisplacement of the A/C compressor.

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probeadapter(s) may damage the connector.Q1 EXTERNALLY CONTROLLED VARIABLE DISPLACEMENT COMPRESSOR (EVDC) PERFORMANCE CHECK



NOTE: Variable displacement compressors operate at lower pressures (compared to fixed compressors) anddepend on correct system charge for normal operation.

NOTE: The performance check test is used to determine if the Externally Controlled Variable DisplacementCompressor (EVDC) is able to change the displacement by measuring the amperage to the solenoid andmonitoring the manifold pressure gauges soon after the is engaged.air conditioning clutch

With a manifold gauge set connected, monitor the low side and high side pressures.

Start the engine. Run the engine until it reaches normal operating temperature.

Select the floor position on the HVAC controls. Set the temperature control to full warm and the blower tothe lowest setting. Set the A/C to off. Run for 5 minutes to heat up the climate control housing.

Monitor the multi meter and the manifold gauges. Select the PANEL position on the HVAC controls. Setthe temperature control to full cold and the blower to the highest setting. Set the A/C to on.

Record the highest amperage measurement and the A/C pressures.

Did the amperage initially increase approximately 0.8A, and did the low side pressure decrease and the highside pressure increase and after a few minutes did the amperage and high side pressure decrease and lowside pressure increase?

Yes The Externally Controlled Variable Displacement Compressor (EVDC) is able to change thedisplacement. CHECK refrigerant charge amount. REFER to: (412-00 Climate Control System - General Information,Specifications) .
