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

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


W1-W3:






W3-W4:






W5-W6:






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 could be caused by:
- wiring, terminals, or connectors.
- a low resistance in the passenger air bag module.
- a faulted RCM.
