Air Bag Secondary Warning Chime
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. 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 (IC) monitors the air bag warning indicator status internally and provides an air bag indication status report to the RCM. When a fault is present in the supplemental restraint system (SRS) with the RCM sending the instrument cluster (IC) an air bag warning indicator on request and a fault is detected in the air bag warning indicator, the RCM sends the instrument cluster (IC) a secondary request to sound the air bag warning chime.
The air bag secondary warning chime inputs are:
- Ignition switch RUN/START status.
- Air bag warning indicator request communicated by the RCM to the instrument cluster (IC).
- Air bag warning indicator chime request communicated by the RCM to the instrument cluster (IC).
