Normal Operation
The Restraints Control Module (RCM) checks for passenger air bag circuit shorts to battery or ignition by monitoring the voltage of circuits 607 (LB/OG) and 616 (PK/BK) at Pins 6 and 7. If the RCM detects a short to battery or ignition on either of these pins, it will store a Diagnostic Trouble Code (DTC) B1925 in memory and flash a Lamp Fault Code (LFC) 16 (or higher priority code if one exists) on the air bag indicator.
Possible Causes
A passenger air bag circuit short to battery or ignition can be caused by:
^ a short to battery or ignition on circuit 607 (LB/OG).
^ a short to battery or ignition on circuit 616 (PK/BK).
^ a short to battery or ignition on the passenger air bag module.
^ an RCM internal concern.
