Air Bag Secondary Warning Chime

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The air bag secondary warning chime warns that the air bag warning indicator light does not work correctly. The instrument cluster monitors the air bag warning indicator status internally. When a fault is present in the air bag warning indicator and the instrument cluster receives an air bag warning indicator on request from the RCM, the air bag secondary warning chime sounds.

The air bag secondary warning chime inputs are:

Ignition switch RUN/START status.
Air bag warning indicator request data is communicated by the RCM to the instrument cluster.
