Test L: Driver-Side Air Bag Circuit Short To Ground (DTC B1887): Description
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. 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 ground by monitoring voltage at RCM harness connector terminals No. 3 (Gray/Orange wire) and No. 4 (Gray/White wire). If RCM detects short to ground in either terminal, it will store Diagnostic Trouble Code (DTC) B1887 in memory and flash Code 15 on AIR BAG warning light.
