PINPOINT TEST S: LFC 16/DTC B1925 - PASSENGER AIR BAG CIRCUIT SHORTED TO BATTERY OR IGNITION

Test S1:

Test S2:

Test S3-S4:

Test S5-S6:

Normal Operation
The restraints control module (RCM) checks for passenger air bag circuit shorts to battery or ignition by monitoring the voltage of circuits 30S-JA11 (RD/WH) and 31S-JA11 (BK/WH) 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 30S-JA11 (RD/WH).
- a short to battery or ignition on circuit 31S-JA11 (BK/WH).
- a faulted RCM.
