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

Normal Operation

The air bag Electronic Crash Sensor (ECS) module monitors the resistance of the passenger air bag ignitor by measuring the resistance between pins 14 and 28. If the ECS 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 damaged or inoperative ECS module.
