MID 036 - CID 0041 - FMI 03 8 Volt DC Supply short to +batt
Conditions Which Generate This Code:
The voltage supply from the Electronic Control Module (ECM) to one of the following sensors has exceeded the normal range.
- Detonation sensors
- Sensor for inlet air pressure
- Sensor for engine coolant pressure
System Response:
Default values are assumed for the inputs to the ECM from all of the 8 volt analog sensors. All of the diagnostic codes for the 8 volt analog sensors to the ECM are disabled while this code is active.
The fuel is shut off. The shutdown output is activated. The code is logged.
Possible Performance Effect:
Since the engine protection is disabled, the engine is shut down.
Troubleshooting:
Test Step 1. Perform the following diagnostic procedure: "+8V Sensor Voltage Supply"
Results:
- OK - STOP
