MID 036 - CID 0445 - FMI 03 Run Relay short to +batt
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects excessive current for the run relay.
Note: This diagnostic condition cannot be detected when the output for the "Run" relay is OFF. The output is normally OFF when the engine control switch is in the STOP position.
System Response:
The ECM will limit the current to 0.3 amperes. The "Status" screen of the Caterpillar Electronic Technician (ET) will display "Relay Fault". The code is logged.
Troubleshooting:
Test Step 1. Perform the following diagnostic procedure: "ECM Status Indicator Output"
Results:
- OK - STOP
