Air Bag Secondary Warning Chime
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. 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 IPC 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 IPC an air bag warning indicator on request and a fault is detected in the air bag warning indicator, the RCM sends the IPC 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 IPC.
- Air bag warning indicator chime request communicated by the RCM to the IPC.
