PINPOINT TEST M: LFC 16/DTC B1925 - AIR BAG PASSENGER CIRCUIT SHORT TO BATTERY

M1-M2:

M3-M5:

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:
- wiring, terminals and connectors.
- a faulted RCM.
