Normal Operation

NOTE: Seat side air bag modules or seat side air bag bridge resistors are available on late build vehicles only.

A seat side air bag module provides protection of the thorax area (between the neck and abdomen) of the body, working in conjunction with the head protection provided by a safety canopy module. Only late build vehicles equipped with safety canopy modules are equipped with seat side air bag modules. See AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS).

The restraints control module (RCM) checks all of the seat side air bag circuits for faults. If the RCM detects one of the following faults on any of the seat side air bag circuits, it will store diagnostic trouble code (DTC) B2295 in memory and, depending on the fault, flash a lamp fault code (LFC) 22 or 23 on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- Low resistance
- High resistance or circuit open
- Circuit short to battery
- Circuit short to ground

Possible Causes
A seat side air bag status fault can be caused by:
- wiring, terminals or connectors.
- a faulted seat side air bag bridge resistor.
- a faulted seat side air bag module.
- a faulted RCM.

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: If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the pinpoint test.
