Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the resistance of the driver air bag ignitor by measuring the resistance between pins 1 and 15. If the ECS detects low resistance between these pins, it will store a Diagnostic Trouble Code (DTC) B1934 in memory and flash a Lamp Fault Code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
Driver air bag low resistance could be caused by:

  • a short in the clockspring windings.
  • a short in the wiring harness.
  • a low resistance in the driver air bag module.
