MID 047 - CID 0446 - FMI 05 Air Shutoff Relay open
Conditions Which Generate This Code:
The secondary Electronic Control Module (ECM) detects an open circuit and/or a short circuit to battery condition. The ECM can only detect this condition when the air shutoff relay is not energized.
System Response:
The CID-FMI is logged in memory. The CID-FMI may be viewed on a display module or the Caterpillar Electronic Technician (ET).
Test Step 1. Perform the following test: Air Shutoff System
Results:
- OK - Stop.
- REPAIRED, OK - Stop.
