Normal Operation

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The restraints control module (RCM) checks for driver air bag circuit shorts to ground by monitoring the voltage of circuits 614 (GY/OG) and 615 (GY/WH) at pins 1 and 2. If the RCM detects a short to ground on either of these pins, it will store a diagnostic trouble code (DTC) B1936 in memory and flash lamp fault code (LFC) 19 (or higher priority code if one exists) on the air bag indicator.
