H: LFC 15/DTC B1916 - Driver Air Bag Circuit Short To Batt/Ign

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 Circuits 614 (GY/O) and 615 (GY/W) 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 could be caused by:
- a short to battery or ignition on Circuit 614 (GY/O).
- a short to battery or ignition on Circuit 615 (GY/W).
- a short to battery or ignition on the air bag sliding contact.
- a short to battery or ignition on the driver air bag module.
