Honda Fit: SRS Component Replacement/Inspection After Deployment

NOTE:

• Before doing any SRS repairs, check for DTCs, for the less obvious deployed components (seat belt tensioners, front impact sensors, side impact sensors, etc).

• If there is a breaking or damage found in harness relevant to the replacement parts shown below, replace it, do not repair.

• Do not replace the ODS unit unless it is physically damaged or a specific fault was found during DTC troubleshooting. Because it could complicate troubleshooting other DTCs.

• After a vehicle collision, do the front seat active head restraint inspection.

After a collision where the seat belt tensioners deployed, replace these items:

• SRS unit

• Seat belt tensioner(s)

• Front impact sensor(s)

After a collision where the front airbag(s) deployed, replace these items:

• SRS unit

• Deployed airbag(s)

• Seat belt tensioner(s)

• Front impact sensor(s)

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

• SRS unit

• Deployed side airbag(s)

• Side impact sensor(s) (first)

• Side impact sensor(s) (second)

• B-pillar lower trim

• Front seat assembly (impact side)

• Seat belt tensioner(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)

• Roof trim

• A-pillar trim

• B-pillar upper trim

• Quarter pillar trim

• Front grab handle

• Rear grab handle

• All related trim clip(s)

• 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

Quarter 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, 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 than 8 mm (0.3 in).   To check the overlap, do this:

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

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

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

   • If the overlap is less than 8 mm (0.31 in),   remove the tape, and install the pillar trim.

   • If the overlap is more than 8 mm (0.31 in),   go to step 4.

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

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