PINPOINT TEST N: LFC 32/DTC B1932 - AIR BAG DRIVER CIRCUIT OPEN


N1-N3:






N3-N4:






N5-N7:






Normal Operation
The restraints control module (RCM) monitors the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM detects an open or high resistance between these pins, it will store a diagnostic trouble code (DTC) B1932 in memory and flash a lamp fault code (LFC) 32 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
Driver air bag circuit open/high resistance can be caused by:
- wiring, terminals or connectors.
- a faulted clockspring.
- a faulted driver air bag module.
- a faulted RCM.
