Y: LFC 36/DTC B1995 - Driver Side Air Bag Ckt Resistance Low

Normal Operation
The Restrains Control Module (RCM) monitors the resistance of the driver side air bag circuit loop and the air bag module igniter at RCM C1 pin 2 and 3. If the resistance is less than 1.4 ohms, the RCM will store Diagnostic Trouble Code (DTC) B1995 and flash Lamp Fault Code (LFC) 36.

Possible Causes
A low resistance on the driver side air bag circuit can be caused by:
- damaged wiring on circuit 1257 (WH/LB).
- damaged wiring on circuit 1258 (BN/LB)
- damaged driver side air bag module.
- damaged RCM.
- worn or damaged shorting bar or camming beam in C233 or C313.
