Normal Operation
The restraints control module (RCM) monitors all front air bag module circuits for faults.The RCM will set a diagnostic trouble code (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 5.0 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 5.0 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 illuminate the air bag warning indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- Loop resistance less than 0.9 ohm (Low resistance)
- Loop resistance greater than 5.0 ohms (Circuit open)
- Circuit short to voltage
- Circuit short to ground

Possible Causes
A driver air bag fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty clockspring.
- a faulty driver air bag module.
- RCM is faulted.

A passenger air bag fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty passenger air bag module.
- RCM is faulted.
