Normal Operation
The Restraints Control Module (RCM) checks for passenger air bag squib 1 circuit shorts to battery and ground by monitoring circuits 607 (LB/OG) and 616 (PK/BK) at RCM C310a pins 5 and 6. If the RCM detects a short to battery or ground on either of these pins, it will store Diagnostic Trouble Code (DTC) B1888 or B1925 in memory and flash Lamp Fault Code (LFC) 16 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger air bag squib 1 circuit short to battery or ground can be caused by:
^ a short to battery or ground on circuit 607 (LB/OG).
^ a short to battery or ground on circuit 616 (PK/BK).
^ a short to battery or ground in the passenger air bag module.
^ an RCM internal concern.
