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

PINPOINT TEST H: 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 0.9 ohm or greater than 5 ohms. The normal expected resistance range of driver air bag loop 1 and loop 2 is 1.47 to 4.26 ohms and 1.23 to 3.31 ohms for the passenger air bag loop 1 and loop 2. If a driver air bag loop resistance is between 0.9 and 1.47 or between 4.26 and 5 ohms and a passenger air bag loop resistance is between 0.9 and 1.23 or between 3.31 and 5 ohms, a DTC will not set but 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.
