Test V: LFC 36/DTC B1994 - Driver Side Air Bag Circuit Resistance Hi

V1 - V2:

V2 - V3:

V4 - V5:

V6 - V7:

V8:

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 pins 2 and 3. If the resistance is greater than 3.6 ohms, the RCM will store Diagnostic Trouble Code (DTC) B1944 and flash Lamp Fault Code (LFC) 36.

Possible Causes
A high 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.
