Engine Control Module (ECM)

ENGINE CONTROL MODULE (ECM)





The ECM (engine control module) is located in the E-Box on the RH (right-hand) side of the engine compartment at the front.

System ECM (engine control module) has the following inputs:
^ RCM (restraints control module)
^ Park/neutral switch
^ Ignition coil feedback x2
^ Fuel rail temperature
^ Fuel rail pressure
^ Supercharger inlet pressure
^ Mass air flow
^ Engine speed
^ Camshaft position x2
^ Driver demand
^ Brake pedal position switch
^ Speed control switches
^ Generator load
^ Oxygen sensors pre catalyst x2
^ Oxygen sensors post catalyst x2
^ Throttle position
^ Cooling fan speed
^ Ignition switch position
^ Knock sensors x2
^ MAP (manifold absolute pressure)
^ Intercooler temperature
^ Coolant temperature
^ Engine oil temperature
^ Air inlet temperature

The ECM (engine control module) outputs to the following:
^ Throttle actuator
^ Brake vacuum pump relay
^ Ignition coils (x8)
^ Oxygen sensor heaters (4)
^ Fuel injectors (8)
^ Purge valve
^ Engine cooling fan
^ Air conditioning condenser cooling Fan
^ Fuel pump relay
^ Starter relay
^ EMS Main relay
^ Generator control
^ Diagnostic Module Tank Leakage (DMTL) (NAS Only)
^ E-box fan
^ FPDM (fuel pump driver module)
^ Air conditioning condenser cooling fan (+ 50Degrees Celsius markets)

ECM ADAPTIONS
The ECM (engine control module) has the ability to adapt the values it uses to control certain outputs. This capability ensures the EMS can meet emissions legislation and improve the refinement of the engine throughout its operating range.

The components which have adaptions associated with them are:
^ The APP (accelerator pedal position) sensor
^ The HO2S
^ The MAF (mass air flow) /IAT (intake air temperature) sensor
^ The CKP (crankshaft position) sensor
^ Electric throttle body.
