Air Bag Systems: Service and Repair

SRS Component Replacement/Inspection After Deployment

NOTE:

- Before doing any SRS repairs, Clear the DTCs with the HDS, for the less obvious deployed parts (seat belt tensioners, front impact sensors, side airbag sensors, etc.)
- Do not replace the ODS unit unless it is physically damaged or a specific fault was found during DTC troubleshooting.
- After a vehicle collision, do the ODS unit operation check ODS Unit Operation Check.
- After a vehicle collision, inspect the front seat active head restraints Testing and Inspection.

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
- Dashboard

After a collision where the side airbag(s) deployed, replace the items for the side(s) that deployed:

- SRS unit
- Deployed side airbag(s)
- Reinforcing cloth rear hooks
- Side impact sensor(s) (first)
- Side impact sensor(s) (second)
- Rear safing sensor
- B-pillar lower trim
- Seat frame and related parts
- Seat belt tensioners(s)

After a collision where a side curtain airbag has deployed, replace the items for the side(s) that deployed:

- SRS unit
- Deployed side curtain airbag(s)
- Seat belt tensioner(s)
- Side impact sensor(s) (first)
- Side impact sensor(s) (second)
- Rear safing sensor
- Roof trim
- A-pillar trim
- B-pillar upper trim
- Quarter-pillar trim
- Front grab handle
- Rear grab handle
- All related trim clips
- Sunvisor

After a moderate to severe side or rear collision, inspect for any damage on the side curtain airbag or other related components. Replace the components as needed.

During the repair process, inspect these areas:

- Inspect all the SRS wire harnesses. Replace, do not 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 to 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 Check for DTCs with the HDS. If you cannot retrieve a code, do the SRS Symptom Troubleshooting.

Checking and Adjusting the Headliner/Pillar Trim Overlap

To prevent the side curtain airbag from deploying and damaging the pillar trim, the overlap between the headliner and pillar trim must be less then 8 mm (0.3 in) To check the overlap, do this:

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





This illustration shows the A-pillar.

2. Apply masking tape to the headliner, mark the upper edge of each pillar trim.





This illustration shows the A-pillar.

3. Remove the pillar trim, and measure the headliner overlap.

- If the overlap is less than 8 mm (0.3 in), remove the tape, and install the pillar trim.
- If the overlap is more than 8 mm (0.3 in), go to step 4.





This illustration shows the A-pillar.

4. Carefully trim the headliner with a utility knife, reducing the overlap to less than 8 mm (0.3 in).





This illustration shows the A-pillar.

5. Remove the tape, and install the pillar trim.
