Pinpoint Test AS: LFC 16/DTC B1925 - Passenger Air Bag Circuit Shorted to Battery or Ignition

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.
