Fuse
System Operation Description:
A fuse is blown out as a result of an overloaded circuit. For example, the +battery connection is shorted to ground. If the fuse is blown on a supply circuit for the ECM, no diagnostic code will be recorded. A blown fuse does not cause a diagnostic code to be recorded in the Machine ECM.
Test Step 1. CHECK THE FUSE
Whenever the machine's electronic components fail to function and no diagnostic code is available, check the appropriate fuse for that component and check all associated circuit breakers.
- Check all fuses and circuit breakers.
Expected Result:
All fuses and circuit breakers are correct.
Results:
- YES - All fuses and circuit breakers are correct. Exit this procedure and repeat this procedure.STOP
- NO - All fuses and circuit breakers are not correct.
Repair: Replace the blown fuse or reset the circuit breaker.
