Normal Operation

WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The air bag warning indicator receives voltage through the instrument cluster when the ignition switch is in the START/RUN position. The instrument cluster illuminates the air bag warning indicator when it receives an open (no ground) from the restraint control module (RCM) on control circuit 608 (BK/YE). The instrument cluster turns off the air bag warning indicator if it receives a ground signal from the RCM on control circuit 608 (BK/YE).
