Repairs and Inspections Required After a Collision: Service and Repair
Inspection and Repair After A Supplemental Restraint System (SRS) Deployment
Inspection and Repair After a Supplemental Restraint System (SRS) Deployment
WARNING: Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental
restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a
crash and possibly violate vehicle safety standards.
NOTE: After diagnosing or repairing a supplemental restraint system (SRS), the restraint system diagnostic tools (if required) must be removed
before operating the vehicle over the road.
NOTE: Deployable devices (such as air bag modules, pretensioners) may deploy alone or in various combinations depending on the impact event.
NOTE: Always refer to the appropriate workshop manual procedures prior to carrying out vehicle repairs affecting the SRS and safety belt system.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
1. NOTE: Refer to the correct removal and installation procedure for all SRS components being installed.
When any deployable device or combination of devices are deployed and/or the restraints control module (RCM) has the DTC B1231 (Event
Threshold Exceeded) in memory, the repair of the vehicle's SRS is to include the removal of all deployed devices and the installation of new
deployable devices, the removal and installation of new impact sensors, and the removal and installation of a new RCM. DTCs must cleared from
all required modules after repairs are carried out.
Vehicles with occupant classification sensor (OCS) system
2. NOTE: After installation of new occupant classification sensor (OCS) system components carry out the OCS System Reset procedure as
instructed in the workshop manual. Refer to the appropriate workshop manual for OCS system removal and installation procedure.
When a vehicle has been involved in a collision and the occupant classification system module (OCSM) has DTC B1231 stored in memory, the
repair of the OCS system is to include the following procedures for the specified system:
For rail type OCS system, inspect the passenger side floorpan for damage and repair as necessary. Install new OCS system rails.
For weight sensor bolt type OCS system, inspect the passenger side floorpan for damage and repair as necessary. Install a new seat track with
OCS system weight sensor bolts. DTC must be cleared from the OCSM before carrying out Occupant Classification Sensor (OCS) System
Reset. Do not install a new OCSM unless DTC B1231 cannot be cleared.
NOTE: Most bladder type OCSM do not store a DTC B1231 in memory after deployment. The DTC B1231 is stored only by the RCM.
For bladder type OCS system, inspect for damage and repair as necessary. If installation of an OCS system component is required, an OCS system
service kit must be installed.
3. When any damage to the impact sensor mounting points or mounting hardware has occurred, repair or install new mounting points and mounting
hardware as needed.
4. When the driver air bag module has deployed, a new clockspring must be installed.
5. New driver and/or front passenger safety belt systems (including retractors, buckles and height adjusters) must be installed if the vehicle is
involved in a collision that results in deployment of the driver and/or front passenger safety belt pretensioners. For additional information, refer to
Safety Belt System.
6. Inspect the entire vehicle for damage, including the following components:
Steering column (deployable column if equipped)
Instrument panel knee bolsters and mounting points
Instrument panel braces and brackets
Instrument panel and mounting points
Seats and seat mounting points
Safety belts, safety belt buckles and safety belt retractors.
