C9 Generator Set Engines Caterpillar


CID 0041 FMI 03 8 Volt DC Supply short to +batt

Usage:

C9 C9E
Conditions Which Generate This Code:

The voltage level of the 8 volt supply is above normal.

System Response:

The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags all digital sensors as invalid data and all digital sensors are set to the respective default values.

Possible Performance Effect:

  • The engine may experience low power.

Troubleshooting:

Test Step 1. Perform the following diagnostic procedure: "Digital Sensor Supply Circuit - Test"

Results:

  • OK - STOP
