Air Bag Control Module: Testing and Inspection

CAUTION: When servicing the air bag diagnostic monitor with a blown internal fuse (diagnostic trouble code 51), find and repair all wire damage or shorts. A blown air bag diagnostic monitor can be used to find electrical faults without replacing components unnecessarily. The Diagnosis and Testing portion is written to give safety first priority.

The following steps may be taken to find the cause that initiated a blown fuse:
1. Verify the system using the old air bag diagnostic monitor and verify the wiring repairs success before proceeding. Repeat as many times as required.
2. Replace the air bag diagnostic monitor when all wire repairs are complete.
3. If the diagnostic trouble code returns after making all wiring repairs, then replace the indicated component.
