Test R

PINPOINT TEST R: LFC 36/DTC B1994 - DRIVER SIDE AIR BAG CIRCUIT RESISTANCE HIGH

Test R1:

Test R2-R3:

Test R4-R6:

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) B1994 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.
