One needs to inspect and repair the Supplemental Restraint System following any collision to ensure safety. Road tests should only proceed after removing diagnostic tools used for restraint systems from vehicles to stop the SRS from failing to activate in crashes that could result in fatal injuries. The removal of deployed air bag modules and pretensioners with fresh equivalents becomes necessary when deployable devices underwent deployment or when restraints control module (RCM) shows Event Threshold Exceeded as DTC B1231. The necessary modules require clearing of all DTCs after successful repairs. Inspection of the passenger side floorpan needs to be done when the occupant classification system module (OCSM) holds DTC B1231. Necessary floorpan repairs should then be conducted and rail type systems need new OCS rails with weight sensor bolt type systems requiring new seat tracks and weight sensor bolts. Perform OCS System Reset only after clearing the DTC that exists in the OCSM from the module. An inspection of bladder type OCSMs without stored DTC B1231 should be performed to check for damages while installing an OCS system service kit if required. The servicing technician should inspect the impact sensor mounting points to determine whether they need replacement or repair. The installation of a new
Clock Spring becomes necessary when the driver air bag module has experienced a deployment. Repair technicians must install new safety belt systems that include retractors as well as buckles and height adjusters whenever driver and front passenger pretensioners operate during deployment. A thorough vehicle inspection must identify damage occurring on the steering column with its instrument panel knee bolsters as well as braces, brackets, safety belts and SRS wiring and seats. post-inspection programs should replace components that show damage.
