Component Replacement/Inspection After Deployment

NOTE: Before doing any SRS repairs, use the HDS
method to check for DTCs; refer to the DTC
Troubleshooting Index for the less obvious deployed
parts (seat belt tensioners, front sensors, side airbag
sensors, etc.).

After a collision where the front airbags deployed,
replace these items:

• SRS unit
• Airbags
• Seat belt tensioners

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

• Seat belt tensioners
• SRS unit
• Front sensors

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

• SRS unit
• Deployed airbag(s)
• Seat belt tensioners
• Front sensors

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

• SRS unit
• Deployed side airbag(s)
• Side impact sensor(s) for side(s) deployed

During the repair process, inspect these areas:

• Inspect all the SRS wire harnesses. Replace, don’t

repair, any damaged harness.

• 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. 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 to read the DTC(s). If this doesn’t retrieve
any codes, use the Tester’s SCS menu method. If the
SCS method doesn’t work, you may need to install a
known-good SRS unit to read the DTC(s). If you still
cannot retrieve a code, go to SRS Indicator Circuit
Troubleshooting.

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

• Seat belt tensioners
• SRS unit
• Front sensors

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

• SRS unit
• Deployed airbag(s)
• Seat belt tensioners
• Front sensors

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

• SRS unit
• Deployed side airbag(s)
• Side impact sensor(s) for side(s) deployed

During the repair process, inspect these areas:

• Inspect all the SRS wire harness. Replace, don’t

repair, any damaged harness.

• 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 (see page 23-42) must be checked after any of
these actions.

• Replacement of front passenger’s seat component(s)
• After a vehicle collision
