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)
