Fasten Safety Belt Warning

The radio activates the fasten safety belt audible warning as requested by the BCM. The BCM sends a class 2 message to the radio indicating the chime frequency of a slow rate and an 8 second 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 inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is not buckled and or the signal is low. The SDM sends a class 2 message to the body control module (BCM) indicating the seat belt status. The IPC receives a class 2 message from the BCM indicating the driver's 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.
