PINPOINT TEST W: LFC 35/DTC B1935 - PASSENGER AIR BAG CIRCUIT RESISTANCE LOW

Test W1-W2:

Test W2-W3:

Test W4-W5:

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 faulted RCM.
- a worn or damaged electrical connector shorting bar.
- a worn or damaged electrical connector camming beam.
