129ROYAL ENFIELD HIMALAYAN EURO IV VEHICLE SERVICE MANUAL
Anti-Lock Braking System (ABS) fitted in Royal Enfield motorcycles, is a safety system to help the front and rearwheels maintain traction with the road surface in the event of sudden application of brakes by the rider at high speeds.
It helps prevent the brakes from “locking” the wheels which can potentially cause the motorcycle to skid and result inloss of control and an accident.
WORKING PRINCIPLEDuring hard application of brakes, the sudden increase in the hydraulic force to the front and rear brakes arecontrolled by a hydraulic pressure moderator which constantly reduces the excessive force on the hydraulic systemthereby ensuring the brake pads do not lock the brake discs. The moderator is controlled by an Electronic controlunit which not only receives real time inputs on the wheel speeds through sensors fitted near the wheel hubs but alsoprovides inputs to the valves in the moderator to regulate the hydraulic pressure such that the brake pads do not lockthe brake disc and cause the motorcycle to skid during emergency brake applications.
CAUTION:While ABS assists in improved vehicle control during braking, decreased stopping distances on dry and graveledsurfaces, it may not be very effective in wet, snow covered, off road, conditions, loose gravel surfaces, hilly roads etc.,since the traction of the wheel itself will be very minimal in these conditions.
As far as possible, all braking, including emergency braking should be done with the motorcycle upright and in a straightmotion. Avoid hard braking when banking heavily at great speeds.
Caution must be exercised by the rider for safe riding of the motorcycle and judge stopping distancesrequired, depending on the speed at which the motorcycle is travelling.
As soon as the ignition and engine stop switch are switched ‘ON’, the ABS sign will light up. The lampwill remain ‘ON’ till the motorcycle attains a speed of 5 Kmph. (3MPH) and then switch ‘OFF’. Thisindicates the ABS is working properly.
In the event the lamp does not switch ‘OFF’ and remains continuously ‘ON’ at higher speeds, it is recommended not toride the motorcycle and get the brake system inspected and corrected through a nearest authorized Royal EnfieldDistributor.

154 ROYAL ENFIELD HIMALAYAN EURO IV VEHICLE SERVICE MANUAL
GENERAL PRECAUTIONS Check the system for any fluid leaks at banjo union joints, damaged brake hose etc. at periodic intervals as detailed
in the maintenance schedule.
Whenever checking brake fluid level, ensure vehicle is on its centre stand and the fluid reservoir is parallel to theground, whenever checking fluid level.
Cover motorcycle painted surfaces, plastic and rubber parts while overhauling or bleeding a brake system. Donot allow brake fluid to come in contact with any parts of the motorcycle as brake fluid has highly corrosiveproperties.
CLEANING
Clean master cylinder filler cap before removing.
Use only fresh brake fluid to clean rubber and other parts of the hydraulic brake system. DO NOT use anypetroleum based cleaning solvents, water or detergents etc.
INSPECTION:
Inspect brake fluid level is always between the MAX and MIN level markings in the reservoir.
Prior to riding the motorcycle every time, check brake disc inside and outside surfaces carefully for anycontamination with oil, grease, slippery substances, brake fluid etc. as these will render the braking systemineffective. In case of any contamination, wash the brake disk with water and mild detergent to remove thecontaminations, clean well with a good degreasing agent, blow compressed air to dry the brake disc thoroughly.
Inspect brake hose joints; reservoir and wheel caliper ends for any traces of fluid seepage or leaks. Check andcorrect the leaks immediately, if any noticed.
Inspect Brake hoses for any damage, cracks or cuts, ageing etc and replace damaged parts immediately.
Inspect brake pads for embedded foreign objects, abnormal wear, age hardening of friction material etc.
Inspect and ensure the pads are not worn out beyond the wear indication limit marks on the pads. Replace padsas soon as they have reached the wear limit marks
Check rubber seals on the plunger for wear, cracked edges or any other damage. Replace seals whenever theplunger is removed
Check master cylinder housing and piston for any scoring, pitting due to corrosion or any other damages.
Check the master cylinder bore for any damages, scoring marks etc.
Check piston outside surfaces for any damages, scoring marks, corrosion etc. Replace pistons if any of the aboveis observed.
CAUTION: Use only DOT 3 or DOT 4 grade brake fluid from a sealed container. Do not mix different types of brake fluid
as they may not be compatible.
Whenever the disc brake system is overhauled, ensure that the old fluid is drained out completely and then filledwith fresh brake fluid ONLY from a sealed container.
In case of any brake fluid contamination in the brake system, the contaminated brake fluid must be flushed outcompletely from the entire system, the internal parts cleaned well, filled with fresh brake fluid and the brakesystem bleeding must be carried out.
www.hitchcocksmotorcycles.com
155ROYAL ENFIELD HIMALAYAN EURO IV VEHICLE SERVICE MANUAL
Always replace brake pads as a set only.
Always replace banjo union washers, ‘O’ rings, diaphragm washers, dust seals and piston seals whenever thehydraulic disc brake system is overhauled.
Always replace damaged parts like pistons, fixing pin etc. DO NOT attempt to repair damaged pistons, pins,master cylinder, caliper etc. as it may render the disc brake system to become ineffective and seriously affectbraking efficiency.
Ensure the brake disc is clean and dry at all times for the brakes to work at peak efficiency.

GENERAL INSTRUCTIONS – DISC BRAKE
Check, monthly or every 2000 kms., the Brake fluid level through the Sight-glass whether it is above the‘MINLINE’ mark. While checking, turn the handle bar straight, until the reservoir is horizontal.
Never mix different types of brake fluids. (DOT 4 & ABOVE Together)
Do not clean the rubber parts with petrol or any other gasoline product or water. Use clean brake fluid only.
In case of water contamination of Brake fluid, drain the fluid completely, refill the system and bleed.
Do not top up brake fluid above “Max” level to avoid front wheel binding problem
Check periodically whether the Disc has been contaminated with oil, brake fluid or grease and clean contaminatedDisc with a high quality brake-degreasing agent.
Always keep the disc clean and dry at all times for the brakes to work at peak efficiency.

The purge valve is a mechanically controlled one way valve. When the engine is off, the purge valve is closed. When theengine is started, the vacuum created in the suction port is used to open this one way valve and allow the vapors togo into the inlet port.
The Evaporative emission control system EVAP fitted in our motorcycles prevents gasoline vapors from escapinginto the atmosphere from the fuel tank.
As soon as the motorcycle is parked after riding or parked under the sun, the hot radiation from the engine / sunlightcauses the fuel in the tank to warm up and releases fuel vapors.
The EVAP system prevents these fuel vapors recycled to engine to avoid vapor into the atmosphere and stored in acharcoal canister.
As soon as the engine is started, these vapours are purged from the canister, into the combustion chamber.
The system consists of a canister, purge valve, rubber hoses, connectors and a sealed fuel tank cap.

SECTION 15 -ENGINE MANAGEMENT SYSTEM (EMS)
www.hitchcocksmotorcycles.com
181ROYAL ENFIELD HIMALAYAN EURO IV VEHICLE SERVICE MANUAL
The EMS consists of an Electronic Control Unit (ECU) which constantly receives inputs like engine temperature,ambient temperature, throttle position, manifold air pressure, exhaust emissions through the various sensorsprovided to optimize the air fuel ratio AND crank position (from the crank position sensor) in relation to the engineRPM to optimize the ignition advance for proper combustion of the air fuel mixture.
This is very essential for:
- Compliance with BS IV regulation related to exhaust emissions
- Optimum fuel efficiency and power output
- Excellent cold start ability and sustained high speed drive ability.
FUNCTIONAL DIAGRAM OF THE EMS
In addition to optimizing engine performance, the ECU also has an inbuilt memory by which any EMS relatedmalfunctions will get stored and help diagnose the fault accurately.
There is also an inbuilt safety system, which, in the event of the motorcycle’s banking angle is below 60o OR is involvedin an accident causing the motorcycle to fall over on either of its sides with the gears engaged and the engine running,both the fuel supply and ignition will be cut off to stop the engine and prevent any further damage from being caused.

SPECIFICATIONS / FUNCTIONS OF THE VARIOUS EMS PARTS
1. ELECTRONIC CONTROL UNIT (ECU)
LOCATIONThe Electronic Control Unit (ECU) is located under the seat.
The ECU consists of a microprocessor with two memories Flash Memory and E2 PROM.
Flash memory is an exclusive recording unit. It collects different inputs from various sensors and calculates optimizedvalues and provides the outputs to the respective controlling devices.
E2PROM is an abbreviation for Electronically Erasable Programmable Read Only Memory. This memory recordsinformation related to performance of the various sensors in the EMS on a real time basis AND also records any sensorfailures if it occurs during operation of the motorcycle.
The main advantage of E2PROM is it records data, even when the motorcycle’s electrical system is switched OFF.
This will help in diagnosing the motorcycle performance and also to view the history and defect codes, whenever theRoyal Enfield NACS II diagnostic tool is connected to the socket in the wiring harness of the motorcycle.
Once the defect is diagnosed and corrected, the history of the defect can be erased using the Royal Enfield NACS IIdiagnostic tool.

2. CRANK POSITION SENSOR
LOCATIONThe crank position sensor sends an alternating voltage signal to the powertrain control module, which is used todetermine engine speed and ignition timing. Thus the speed of the engine is instantly known by the ECU.
SPECIFICATIONOutput Voltage: 3 - 5 V AC.
Resistance : 200+20 Ω
It provides an alternating electrical pulse to the ECU, to determine crankshaft speed and TDC position by scanningthe 17 pips and 1 long gap between 2 particular pips on the rotor. This input helps the ECU to optimize both fuelinjection as well as Ignition advance required to suit the crankshaft rotation speed (RPM).
In the event the throttle is held wide open with gears in neutral, leading to crankshaft speed above 5500 RPM, thehigh frequency electrical pulses from the crank position sensor will prompt the ECU to restrict fuel supply so that thecrank speed reduces below 5000 RPM. This is a safety aspect to prevent damage to moving engine parts.
3. ENGINE TEMPERATURE SENSOR
LOCATIONThe engine temperature sensor (EOT) is located on the cylinder head, below the inlet manifold on the oil passage.
It senses the oil temperature and provides the input to the ECU on a real time basis. The ECU can then determine thefuel injector operating time to provide the required amount of vaporized fuel into the combustion chamber foroptimum performance of the motorcycle and also to meet the emission norms.
SPECIFICATIONOperating Temperature: -55°C to + 250°C

LOCATIONThe fuel pump is located on the left side bottom of the fuel tank and submerged in the fuel so that it cannot ignite itselfdue to any electrical short circuits. The fuel pump has an inbuilt micro filter which helps to filter even the minute dustparticles that may come in the fuel.
SPECIFICATIONOperating Voltage: 6 V to 15 V
Operating Temperature: -15°C to +60°C
Fuel Pressure: 294 Kpa
As soon as the Ignition switch and the engine kill switch are in ON position, the fuel pump creates a positive pressureof 294KPa in the fuel line and up to the injector. The fuel pump operation is determined by the ECU so that there is noexcessive pressure in the fuel system to prevent damage to the fuel injector, fuel hose. Any excess pressure is bypassedback into the fuel tank.
11. FUEL INJECTOR
LOCATIONThe fuel injector is located at an angle on the intake side of the cylinder head so as to maximize fuel spray and minimizewall wetting, for optimum performance of the motorcycle.
The Fuel Injector is a solenoid operated electromagnetic valve, which enables the pressurized fuel delivered by thefuel pump, to be atomized and sprayed into the cylinder head combustion chamber.
The fuel injector operation and duration to deliver vaporized fuel is controlled by the ECU based on the criticaloperating inputs received from the crank position sensor, EOT sensor, ambient air temperature sensor, throttleposition sensor, manifold pressure sensor and HEGO sensor.

Fuel Pressure : 343 Kpa
Resistance : 10.3+0.5 Ohms
The EFI ECU Power relay supports functioning of the ECU and fuel pump. The Side stand relay provides the inputsregarding the position of the side stand to the ECU. In the event the side stand is NOT retracted and the motorcycleis attempted to be started, it signals the ECU which cuts off the fuel supply thus preventing the engine from starting.
13. ROLLOVER SENSOR
LOCATIONThe rollover sensor is located on the frame under the seat.
The rollover sensor, also known as a “banking” sensor, is a safety feature. If the banking angle of the motorcycle goesbelow 60o OR in the event of an accident causing the motorcycle to fall over on either of its sides with the enginerunning, the rollover sensor will “command” the ECU to cut off both the fuel supply and ignition, thus stalling theengine to prevent any further damage from being caused by the engine that may be running with a stuck open throttleand the gears engaged.
To re activate the system, the motorcycle should be made upright in its centre stand position, the ignition switch andstop switch must be switched OFF and switched back ON after a few seconds. This will help to RESET the rolloversensor.

EMS FAULT DIAGNOSIS & TROUBLE SHOOTING
NOTE: During diagnosis the motorcycle should be parked in its center stand, the side stand in fully retracted
position and with the gears in neutral .
The battery should be in fully charged and proper working condition.
There should be no external electrical sources or interferences near the motorcycle.
TYPES OF DIAGNOSISThere are three levels of identifying a malfunction in the ECU or the sensors.
LEVEL 1 VISUALAs soon as the ignition switch, engine stop switch are in ON position and the side stand is in fully retractedposition, the MIL will glow and will switch OFF after a few seconds after the engine is started. This indicates theEMS system is in its auto diagnostic mode and the EMS is working perfectly.
In the event the MIL glows continuously and does not switch off, it indicates a malfunction in the EMS.
LEVEL 2 TEST PINIn the event the MIL is continuously ON and does not switch OFF, the test pin method will help narrow down tothe sensor / electrical connection that caused the malfunction.
LEVEL 3 GENERIC SCAN TOOL (NACS II DIAGNOSTIC TOOL)A generic scan tool supplied by Royal Enfield will help identify the exact cause of the malfunction in the EMS,when connected between the motorcycle and a computer.
The tool will take inputs from the ECU and provide to the computer to display the defect code that will helpidentify the specific sensor/connections.
In addition the generic scan tool can also help download the history of the vital parameters of the EMS, engineperformance and earlier defects for detailed analysis and records.
The generic scan tool will also be able to erase previous defects after the same has been rectified.
METHOD OF CHECKING
LEVEL 1 VISUAL Switch OFF the ignition and engine stop switch.
Check for any loose coupler connections at the sensor end. Correct loose connections if any.
Switch ON ignition and engine stop switch. Ensure side stand is fully retracted.
Check for MIL Indication in the cluster/Console.
- Start the engine.
- Allow engine to run in idling RPM for about 30 seconds and switch off engine.
www.hitchcocksmotorcycles.com
216 ROYAL ENFIELD HIMALAYAN EURO IV VEHICLE SERVICE MANUAL
- Repeat the above process for 2 more times.
- Ensure MIL Indications goes off after above method.
- This will help to recalibrate the MIL and store the error code in the ECU.
If in case the defect is not eliminated and the MIL glows continuously, proceed to level 2 test pin methodto resolve the defect.
LEVEL 2 TEST PIN METHODAn open single pole connector is provided close to the UCE.
Connect a piece of wire to this connector and suitably ground it to the motorcycle body.
Switch ON ignition and engine stop switch and observe the MIL keenly for a series of short and long blinksat different intervals, to identify the defective sensor / wiring connection as detailed in the table below,
