Pinpoint Test J: LFC 33, 34 And 38/DTC B2292 - Restraint System Safety Belt PRETENSIONER Status
- J1 CHECK FOR CONTINUOUS OR ON-DEMAND DTCs WARNING:
- Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards.
- Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow these instructions may result in the inadvertent deployment of the safety canopy and risk of 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.
- 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 electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
NOTE:- If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.
- After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road .
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
