Component Replacement/Inspection After Deployment
NOTE: Before doing any SRS repairs, check the SRS DTCs (see page 24-22) for the less obvious deployed
components (seat belt tensioners, front impact
sensors, side airbag sensors, etc.).
 After a vehicle collision, do the ODS unit operation check (see page 24-28).
 Do not replace the ODS unit unless it is physically damaged or a specific fault was found during DTC
troubleshooting.
 After a vehicle collision, inspect the front seat active head restraints (see page 20-117).
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
 Side impact sensor(s) (first)
 Side impact sensor(s) (second)
 B-pillar lower trim
 Front seat assembly (Impact side) After a collision where a side curtain airbag deployed,
replace the items for the side(s) that deployed:
 SRS unit
 Deployed side curtain airbag(s)
 Seatbelttensioner(s)
 Side impact sensor(s) (first)
 Side impact sensor(s) (second)
 Rear safing sensor
 Roof trim
 A-pillar trim
 B-pillar lower trim
 C-pillar trim
 Front grab handle
 Rear grab handle
