Air Bag Control Module: Service Precautions

Supplemental Restraint System Module (SRS), Reuse

NOTE: The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

When repairing a crashed vehicle, the Volvo policy is to replace those systems that may have been damaged where full function cannot be guaranteed.

What is replaced and when?
Driver/passenger airbag modules and seat belt tensioners indicate clearly when they have deployed and must be replaced.

When a driver and/or passenger airbag module has deployed:
- all seat belt tensioners, seat belt buckles and end mountings in the rear seat (and in the third row rear seat where applicable) have been activated and should therefore be replaced
- the seat belt tensioners in the front seats are checked, as activation of the tensioner function depends on whether seat belt was in use or not.

When the vehicle is subjected to collision forces without the driver and/or passenger airbag module deploying:
- all the seat belt tensioners in the car must be checked.

Procedures
When replacing seat belts that were in use in a collision, cut the seat belt to prevent reuse.
