Safety Belt Retractor and Pretensioner
SAFETY BELT RETRACTOR AND PRETENSIONER
Removal
WARNING:
- All safety belt assemblies (including retractors, belt tension sensors [BTS] if equipped, buckles, shoulder belt height adjusters [if so equipped], child safety seat tether attachments and attaching hardware) should be inspected after any collision. All new belt assemblies should be installed unless a qualified technician finds the assemblies show no damage and operate correctly. Belt assemblies not in use during a collision should also be inspected and new assemblies installed if either damage or incorrect operation is noted.
The automatic locking retractor (ALR) feature of the safety belt retractor must be checked by a qualified technician to verify that the ALR feature for a child safety seat is functioning correctly, in addition to other checks for correct safety belt system function. A new belt and retractor assembly must be installed if the safety belt assembly's "automatic locking retractor" feature or any other safety belt function is not operating correctly when inspected according to the functional inspection procedures. Failure to install a new belt and retractor assembly could increase the risk of injury in collisions.
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
- The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- To reduce the risk of personal injury, do not use any memory saver devices.
NOTE:
- The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
