Air Bag Warning Chime

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The air bag warning chime warns the driver that the air bag warning indicator lamp is not working and a fault has occurred by sounding a chime when the ignition switch is in the RUN position for more than 20 seconds. When these conditions exist, the restraint control module (RCM) sends a chime request through communication network to the instrument cluster. The instrument cluster then activates the warning chime. The warning consists of 5 sets of 5 1-second tone bursts. Each set is separated by 5 seconds of silence. The warning is repeated every 30 minutes.
