Test G: DTC B2293 - Restraint System - Air Bag Fault

PINPOINT TEST G: DTC B2293 - RESTRAINT SYSTEM - AIR BAG FAULT

Normal Operation
The restraints control module (RCM) monitors all front air bag module circuits for faults. The RCM will set a DTC if a short to battery or short to ground fault is detected. The RCM will also set a DTC if the loop resistance is less than 1.31 ohm or greater than 5 ohms. The normal expected resistance range is 1.31 to 4.29 ohms. If a loop resistance is between 0.9 and 1.31 or between 4.29 and 5 ohms, there exists a strong potential for an intermittent fault. If the RCM detects a fault on any of the front air bag circuits, it will store DTC B2293 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.
