LFC 34 / DTC B1934 (Steps 5 - 7):




Normal Operation
The air bag diagnostic monitor monitors the resistance for the driver-side air bag ignitor by measuring the resistance between pins 3 and 4. If the air bag diagnostic monitor 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-side air bag low resistance could be caused by:
- A short in the air bag sliding contact windings.
- A short in the wiring harness.
- Low resistance in the driver air bag module.
- Air bag diagnostic monitor internal concern.
- A shorting bar or camming beam concern in the connector.
