Test Z: LFC 36/DTC B1995 - Driver Side Air Bag Circuit Resistance Low

Z1 - Z2:






Z3:






Z4 - Z6:






Normal Operation
The Restraints 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 30S-JA37 (RD/GN).
^ damaged wiring on circuit 31S-JA37 (BK/GN).
^ damaged driver side air bag module.
