Test H: LFC 15/DTC B1916 - Driver Air Bag CKT Short to Batt or Ign

H1 - H2:

H3 - H4:

H5 - H6:

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/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 air bag sliding contact.
^ a short to battery or ignition on the driver air bag module.
