The immobilizer function is a part of a system that prevents the engine from starting if the correct ignition key is not used. After ignition ON, a security code is broadcast from the ECM control unit to the immobilizer control unit or the Instrument cluster (US market). Engine start is permitted if a correct response message is received within a certain number of tries and within a certain time from the immobilizer control unit. Conditions for diagnostic trouble code (DTC):1) Communication fault between Instrument cluster (IC) and Engine control module (ECM) Observable symptoms1) Engine cannot be started Probable cause1) Instrument...

The engine piston cooling oil supply valve is located in the oil filter housing and is used to control the piston cooling oil pressure. The engine control module (ECM) controls the valve by monitoring the signal from the piston cooling oil pressure sensor. If an electrical fault is detected inside the valve it will be fully open (fail safe). Conditions for diagnostic trouble code (DTC):1) Output activated2) The current at pin A14.EB:41 is above 2.2?A Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Low oil pressure at low engine speed Probable cause1) Short circuit to voltage supply, control...
