Safety depends on proper examination and repair of the Supplemental Restraint System (SRS) after a collision has occurred. It is essential to eliminate restraint system diagnostic tools from the vehicle before road testing to stop the SRS device from not deploying during a crash thus causing serious harm or fatal outcomes. The repair process requires deployment device replacement alongside new impact sensors and a Restraints Control Module (RCM) but only when B1231 (Event Threshold Exceeded) is present in RCM memory. Retrieving all relevant DTCs must occur after completing the necessary module repairs. The inspection of passenger side floorpan damage is required when DTC B1231 exists within the occupant classification sensor (OCS) module. New OCS rails must be installed together with seat tracks featuring OCS weight sensor bolts if needed. After deployment the bladder type OCS modules do not maintain DTC B1231 but owners need to replace damaged components with an OCS system service kit if required. You must check and fix any damage found in impact sensor brackets and hardware before exchanging the
Clock Spring when the driver air bag module has fired. The replacement or installation of front safety restraint systems must be performed when pretensioner components operate while the team evaluates vehicle damage across steering column and instrument panel and seats with safety belts and SRS wiring systems. Finish the inspection by performing replacement of components found to be damaged during the assessment process.
