Pinpoint Test AW: LFC 35/DTC B1935 - Passenger Air Bag Circuit Resistance Low

Normal Operation

The Restraints Control Module (RCM) monitors the resistance of the passenger air bag ignitor by measuring the resistance between pins 6 and 7. If the RCM detects low resistance between these pins, it will store a Diagnostic Trouble Code (DTC) B1935 in memory and flash a Lamp Fault Code (LFC) 35 (or higher priority code if one exists) on the air bag indicator.

Possible Causes

Passenger air bag low resistance can be caused by:
- a short in the wiring harness.
- a low resistance in the passenger air bag module.
- a closed shorting bar.
- a damaged camming beam.
- an RCM internal concern.
