Pinpoint Test I: LFC 24 And 25/DTC B2294 - Restraint System - Side Air Curtain Module Fault

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Side air curtain bridge resistor connectors and side air curtain module connectors are similar in appearance, the difference is in the way the connectors are keyed.

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

I1 CHECK FOR A HARD OR INTERMITTENT DTC
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: 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 side air curtain module. Doing so can result in side air curtain deployment.

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.
