Normal Operation
The Restraints Control Module (RCM) monitors the resistance of the passenger side air bag circuit loop and the air bag module igniter at RCM C1 pins 5 and 6. If the resistance is greater than 3.6 ohms, the RCM will store Diagnostic Trouble Code (DTC) B1998 and flash Lamp Fault Code (LFC) 37.

Possible Causes
A high resistance on the passenger side air bag circuit can be caused by:
^ damaged wiring on circuit 1259 (WH/YE).
^ damaged wiring on circuit 1260 (BN/YE).
^ damaged passenger side air bag module.
^ damaged RCM.
