Normal Operation
The restraints control module (RCM) checks all of the front air bag circuits for faults If the RCM detects one of the following faults on any of the front air bag circuits, it will store diagnostic trouble code (DTC) B2293 in memory and, depending on the fault, flash either lamp fault code (LFC) 19 or 21 (or higher priority code if one exists) on the air bag indicator.
Fault Conditions
The RCM monitors for the following fault conditions:
- low resistance.
- circuit open.
- circuit short to voltage.
- circuit short to ground.
Possible Causes
A driver air bag status fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty air bag sliding contact.
- a faulty driver air bag module.
- RCM is faulted.
A passenger air bag status fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty passenger air bag module.
- RCM is faulted.
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.
WARNING: 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.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING: 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.
WARNING: Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment and could result in personal injury.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.
Fault Navigation Table:
Use the fault navigation table after step 1 and step 2 are carried out in pinpoint test 11. If a flagged fault of "?" was recorded, multiple faults exist and the entire pinpoint test must be carried out.
