Test V: LFC 37/DTC B1999 - R Side Air Bag Circuit Resistance Low

V1:

V2:

V3 - V4:

V4:

V5:

V5 - V6:

Normal Operation
The Restraints Control Module (RCM) monitors the resistance of the passenger seat side air bag module circuit loop and the air bag module igniter at RCM C2041b pin 5 and 6. If the resistance is less than 1.4 ohms, the RCM will store Diagnostic Trouble Code (DTC) B1999 and flash Lamp Fault Code (LFC) 37.

Possible Causes
A low resistance on the passenger seat side air bag module circuit can be caused by:
^ damaged wiring on circuit 1259 (WH/YE).
^ damaged wiring on circuit 1260 (BN/YE).
^ damaged passenger seat side air bag module.
^ worn or damaged shorting bar or camming beam in C2041b or C312.
^ a faulted RCM.
