Test F: Driver Air Bag Circuit Short To Ground (DTC B1887): Description
WARNING: This page is about a different car, the 2002 Lincoln Navigator and 2002 Ford Expedition. 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 C2005, terminals No. 3 (Gray/Orange wire) and No. 4 (Gray/White wire). If RCM detects short to ground on either terminal, it will store Diagnostic Trouble Code (DTC) B1887 in memory and flash Code 15 on AIR BAG warning light.
