Normal Operation
The Restraints Control Module (RCM) checks for driver air bag squib 1 circuit shorts to battery and ground by monitoring circuits 614 (GY/OG) and 615 (GY/WH) at RCM C310a pins 2 and 3. If the RCM detects a short to battery or ground on either of these pins, it will store Diagnostic Trouble Code (DTC) B1887 or B1916 in memory and flash Lamp Fault Code (LFC) 15 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver air bag squib 1 circuit short to battery or ground can be caused by:
^ a short to battery or ground on circuit 614 (GY/OG).
^ a short to battery or ground on circuit 615 (GY/WR).
^ a short to battery or ground in the air bag sliding contact.
^ a short to battery or ground in the driver air bag module.
^ an RCM internal concern.
