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; read the DTC for the less obvious deployed parts (seat belt tensioners, front impact sensors, side airbag sensors, etc.)
- Do not mix TRW and Denso impact sensors. Impact sensors and the SRS unit must be of the same manufacturer.
















After a collision where the seat belt tensioners deployed, replace these items:
- SRS unit
- Seat belt tensioners
- 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)
- Seat belt tensioner(s) for the side(s) that deployed.
- Side impact sensor(s) (first) for the side(s) that deployed
- Side impact sensor(s) (second) for the side(s) that deployed (4-door)

After a collision where the side curtain airbag(s) deployed, replace these items:
- SRS unit
- Deployed side curtain airbag(s)
- Seat belt tensioner(s) for the side(s) that deployed
- Side impact sensor(s) (first) for the side(s) that deployed
- Side impact sensor(s) (second) for the side(s) that deployed (4-door)
- Roof trim
- A-pillar trim
- B-pillar trim
- C-pillar trim
- Front grab handle
- Sunvisor
- All related trim clips

After a moderate to severe side or rear collision, inspect for damage on the side curtain airbag or other related components. According to the degree of damage, replace components as needed.

After a collision, where a side curtain airbag has deployed, replace all trim clips on that side, even if they appear to be undamaged. Replace the clips on these parts:
- A-pillar trim
- B pillar trim
- C-pillar trim
- Front grab handle
- Sunvisor

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

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 is OK. If the indicator does not function properly, use the HDS SRS Menu Method to read the DTC. If you cannot retrieve a code, go to SRS Symptom Troubleshooting. Symptom Troubleshooting Index

Checking and Adjusting the Headliner/Pillar Trim Overlap
To prevent the side curtain airbag from accidentally deploying and damaged the pillar trim, the overlap between the headliner and pillar trim must be less then 15 mm (0.6 in.). To check the overlap, do this:




1. Install the headliner (A) and the pillar trim (B)




2. Using masking tape on the headliner, mark the upper edge of each pillar trim.




3. Remove the pillar trims, and measure the headliner overlap.
- 2-door model: If the overlap is less than 12 mm (0. 5 in.), remove the tape, and install the pillar trims.
- 2-door model: If the overlap is more than 12 mm (0. 5 in.), go to step 4.
- 4-door model: If the overlap is less than 15 mm (0. 6 in.), remove the tape, and install the pillar trims.
- 4-door model: If the overlap is more than 15 mm (0. 6 in.), go to step 4.




4. Carefully trim the headliner with a utility knife, reducing the overlap to less than 12 mm (05. in.) (2-door model) or 15 mm (0.6. in.) (4-door model).
5. Remove the tape, and install the pillar trim.
