Air Bag Systems: Service and Repair
Component Replacement/Inspection After SRS Deployment
NOTE:
- Before doing any SRS repairs, use the HDS SRS menu method to check for DTCs.
- Check the front passenger's weight sensors after a vehicle collision. Initial Inspection and Diagnostic Overview
- After a vehicle collision, do the ODS unit operation check. ODS Unit Operation Check
- Do not replace the ODS unit unless it is physically damaged or a specific DTC was found daring troubleshooting.
After a collision where the seat belt tensioners deployed, replace these items:
- SRS unit
- Seat belt tensioners
- Seat belt buckle tensioners
- Front impact sensors
After a collision where the front airbag(s) deployed, replace these items:
- SRS unit
- Deployed airbag(s)
- Seat belt tensioners
- Seat belt buckle 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) (first) for the side(s) that deployed
- Side impact sensor(s) (second) for the side(s) that deployed
- B-pillar lower trim
- Complete seat frame
- Side airbag bracket
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)
- Roll rate sensor
- Roof trim
- A-pillar trim
- B-pillar lower trim
- C-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.
A-pillar trim
B-pillar trim
C-Pillar trim
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 read the DTC. Initial Inspection and Diagnostic Overview 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 0.3 in. (8 mm). 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 trim, and measure the headliner overlap.
- If the overlap is less than 0.3 in. (8 mm), remove the tape, and install the pillar trim.
- If the overlap is more than 0.3 in. (8 mm), go to step 4.
4. Carefully trim the headliner with a utility knife, reducing the overlap to less than 0.3 in. (8 mm).
5. Remove the tape, and install the pillar trim.
