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.
