Normal Operation
The Restraints Control Module (RCM) monitors the resistance of the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM detects low resistance between these pins, it will store a Diagnostic Trouble Code (DTC) B1934 in memory and flash a Lamp Fault Code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
Driver air bag low resistance could be caused by:
^ a short in the clockspring windings.
^ wiring, terminals, or connectors.
^ a low resistance in the driver air bag module.
^ an RCM internal concern.
