Pinpoint Test F: LFC 15/DTC B1916 - Driver Air Bag Circuit Short to Battery or Ignition

Normal Operation

The air bag Electronic Crash Sensor (ECS) module checks for driver air bag circuit shorts to battery or ignition by monitoring the voltage of circuit 614 (GY/OG) and 615 (GY/WH) at pins 1 and 15. If the ECS detects a short to battery or ignition on either of these pins, it will store a Diagnostic Trouble Code (DTC) B1916 in memory and flash a Lamp Fault Code (LFC) 15 (or higher priority code if one exists) on the air bag indicator.

Possible Causes

A driver air bag circuit short to battery or ignition can be caused by:
- a short to battery or ignition on circuit 614 (GY/OG).
- a short to battery or ignition on circuit 615 (GY/WH).
- a short to battery or ignition on the clockspring.
- a damaged or inoperative ECS module.
