Test L: Driver-Side Air Bag Circuit Short To Battery (DTC B1916): Description
WARNING: This page is about a different car, the 2004 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) checks driver-side air bag module circuits for short to battery or ignition voltage by monitoring voltage at RCM harness connector terminals No. 1 (Gray/Orange wire, circuit No. 614) and No. 2 (Gray/White wire, circuit No. 615). If RCM detects short to battery or ignition voltage in either terminal, it will store Diagnostic Trouble Code (DTC) B1916 in memory and flash Code 15 on AIR BAG warning light.
