Pinpoint Test AT: LFC 32/DTC B1932 Driver Air Bag Circuit Resistance High

Normal Operation

The Restraints Control Module (RCM) monitors the resistance for the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM detects 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 high resistance can be caused by:
- a poor connection or corrosion in the driver air bag module circuits or the clockspring.
- an open circuit or high resistance in the clockspring windings.
- an open circuit or high resistance in the wiring harness.
- an open circuit or high resistance in the driver air bag module.
- an RCM internal concern.
