Normal Operation
The Restraints Control Module (RCM) checks for driver air bag squib 2 circuit shorts to battery and ground by monitoring circuits 1516 (YE/WH) and 1517 (RD/OG) at RCM C310b pins 11 and 12. If the RCM detects a short to battery or ground on either of these pins, it will store Diagnostic Trouble Code (DTC) B2228 or B2230 in memory and flash Lamp Fault Code (LFC) 28 (or higher priority code if one exists) on the air bag indicator.
Possible Causes
A driver air bag squib 2 circuit short to battery or ground can be caused by:
^ a short to battery or ground on circuit 1516 (YE/WH) or 1517 (RD/OG).
^ a short to battery or ground on the air bag sliding contact.
^ a short to battery or ground in the driver air bag module.
^ an RCM internal fault.
