Test V

PINPOINT TEST V: LFC 34/DTC B1934 - DRIVER AIR BAG CIRCUIT RESISTANCE LOW

Test V1-V3:

Test V3-V5:

Test V5-V7:

Normal Operation
The restraints control module (RCM) monitors the resistance of the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM detects low resistance between these pins, it will store a diagnostic trouble code (DTC) B1934 in memory and flash a lamp fault code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
Driver air bag low resistance could be caused by:
- a short in the clockspring windings.
- wiring, terminals, or connectors.
- a low resistance in the driver air bag module.
- a faulted RCM.
