Fasten Safety Belt Warning

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The radio activates the fasten safety belt audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the radio indicating the chime frequency and duration. The fasten safety belt warning sounds and the fasten safety belt indicator illuminates when the following occurs:

The ignition switch transitions to ON.
The BCM detects that the driver seat belt is not buckled. The radio receives a serial data message from the BCM indicating the driver seat belt status.

If the seat belt is buckled when the ignition is turned on, the chime does not sound. If the seat belt is buckled while the chime is sounding, the chime stops. If the seat belt is unbuckled after the initial transition to ON, the chime does not sound.
