Safety Belt Buckle and Pretensioner
Removal and Installation
WARNING: After a crash, the following safety belt components and attaching hardware must be inspected and tested to verify correct function:
- Retractors
- Buckles
- Child safety seat tether bracket assemblies
- Automatic locking retractor (ALR) feature for child safety seats (passenger seating positions only)
- Belt tension sensor (BTS) (if equipped)
- Front safety belt buckle support assemblies (slide bar) (if equipped)
- Safety belt shoulder belt height adjusters (if equipped)
Components that do not operate correctly or pass all Functional Tests in the Component Tests must be replaced with new components.
Safety belt assembly attaching areas must be inspected. Damaged or distorted attaching areas must be restored to their original structural integrity and a new safety belt assembly with new attaching hardware must be installed.
After deployment of the front safety belt pretensioners, a new safety belt system (including retractors, buckles and height adjusters) must be installed.
Failure to follow this instruction may result in incorrect operation of the safety belt system and increases the risk of serious personal injury or death in a crash.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
