System Operation Description:
A fuse is blown out or the circuit breaker is tripped as a result of an overloaded circuit. For example, the +battery connection is shorted to ground. If the fuse is blown out or the circuit breaker is tripped on a supply circuit for the ECM, no diagnostic code will be recorded. A power supply circuit that has failed will cause a diagnostic code of CID 0041 FMI 04 to be logged for MID 039.
Test Step 1. CHECK THE FUSES/CIRCUIT BREAKER
Whenever the machine's electronic components fail to function and no diagnostic code is available, check the appropriate fuses/circuit breaker for that component.
