Air Bag Control Module: Service and Repair
CAUTION: When servicing the air bag diagnostic monitor with a blown internal fuse (DTC 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 diagnostic procedures are 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.
Removal and Installation
1. Disconnect battery positive cable and wait one minute for backup power supply energy to be depleted.
WARNING: THE ELECTRICAL CIRCUIT NECESSARY FOR SYSTEM DEPLOYMENT IS POWERED DIRECTLY FROM THE
BATTERY AND BACKUP POWER SUPPLY. TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY,
THE BATTERY POSITIVE CABLE MUST BE DISCONNECTED FOR ONE MINUTE PRIOR TO SERVICING OR REPLACING
ANY SYSTEM COMPONENTS.
NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module
(PCM) relearns its adaptive strategy. The vehicle may need to be driven 10 mites or more to relearn the strategy.
2. Locate air bag diagnostic monitor beneath and to the left of the steering column and disconnect the two connectors.
3. Depress tabs retaining air bag diagnostic monitor to air bag monitor bracket. Slide air bag diagnostic monitor off air bag monitor bracket.
4. Disconnect electrical wiring connectors to air bag diagnostic monitor. Remove air bag diagnostic monitor.
5. For installation, follow removal procedures in reverse order. Prove out system.
