Test M: LFC 34/DTC B1934 - Air Bag Driver Inflator Circuit Resistance Low on Squib

PINPOINT TEST M: LFC 34/DTC B1934 - AIR BAG DRIVER INFLATOR CIRCUIT RESISTANCE LOW ON SQUIB

M1-M3:

M4-M6:

M7-M8:

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 can be caused by:
- wiring, terminals or connectors.
- a faulted clockspring.
- low resistance in the driver air bag module.
- a faulted RCM.
