Normal Operation
The Restraints Control Module (RCM) monitors the driver air bag squib 1 circuit loop at RCM C310a pins 2 and 3, circuits 614 (GY/OG) and 615 (GY/WH). If the RCM detects a low resistance (less than 1.4 ohms), it will store Diagnostic Trouble Code (DTC) B1934 in memory and flash Lamp Fault Code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver air bag squib 1 circuit low resistance can be caused by:
^ a short between circuits 614 (GY/OG) or 615 (GY/WH).
^ a driver air bag module internal fault.
^ an RCM internal fault.
