Engine Diagnostic Chart (cont.)

Starter Relay (high side power stage): The current drop measured by ECU is above the target range; starter relay low side short circuit to ground.

Starter Relay (high side power stage): The current drain measured by ECU is above the target range; starter relay high side, short circuit to ground

Starter Relay (low side power stage): the current drop measured by ECU is above the target range; open circuit/disconnection LowSideOutput

Starter Relay (low side power stage): the current drop measured by ECU is above the target range; starter relay powerstage over temperature

Intake Air Heater Device; short-circuit to battery 7294

Air intake heater; Short circuit to ground error for powerstage on CJ945 7295 Cold Start

Cold start aid relay open load

Timeout error: limp mode activated

Internal Hardware Monitoring: the ECU detects a deviation of the target range of the power supply voltage of sensor output 1

Internal Hardware Monitoring: the ECU detects a deviation of the target range of the power supply voltage of sensor output 2

Operator ignores the engine shut off request within an allowed period.

CAN Bus 1: the ECU is not allowed to send messages, because the status “BusOff” is detected 123514

Override Switch: the ECU receives a permanent signal, plausibility error
