Normal Operation
The Restraints Control Module (RCM) checks for driver air bag circuit shorts to battery or ignition by monitoring the voltage of circuit 614 (GY/OG) and 615 (GY/WH) at pins 3 and 4. If the RCM detects a short to battery or ignition on either of these pins, it will store a Diagnostic Trouble Code (DTC) B1916 in memory and flash a Lamp Fault Code (LFC) 15 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver air bag circuit short to battery or ignition could be caused by:
^ wiring, terminals, or connectors.
^ a short to battery or ignition on the clockspring.
^ a short to battery or ignition on the driver air bag module.
^ an RCM internal concern.
