Air Bag Systems: Service and Repair

Component Replacement/Inspection After Deployment

NOTE: Before doing any SRS repairs, use the HDS SRS Menu Method to check for DTCs; go to the Trouble Code Descriptions for the less obvious deployed parts (seat belt tensioners, front impact sensor, side impact sensors, etc.).

After a collision where the seat belt tensioners deployed, replace these items:
- Seat belt tensioners
- SRS unit
- Front impact sensors

After a collision where the front airbag(s) deployed, replace these items:
- SRS unit
- Deployed airbag(s)
- Seat belt tensioners
- Front impact sensors

After a collision where the side airbag(s) deployed, replace these items:
- SRS unit
- Deployed side airbag(s)
- Side impact sensor(s) for the side(s) that deployed

During the repair process, inspect these areas:
- Inspect all of the SRS floor harnesses. Replace, don't repair, any damaged harnesses.
- Inspect the cable reel for heat damage. If there is any damage, replace the cable reel.

The operation of the front passenger's weight sensor unit must be checked after any of these actions.
- Replacement of front passenger's seat component(s)
- After a vehicle collision

After the vehicle is completely repaired, turn the ignition switch ON (II). If the SRS indicator comes on for about 6 seconds and then goes off, the SRS airbag system is OK. If the indicator does not function properly, use the HDS SRS Menu Method to read the DTC.
