Fasten Safety Belt Warning

The IPC activates the fasten safety belt audible warning as requested by the BCM. The BCM sends a serial data message to the IPC 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 inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is not buckled. The IPC receives a serial data message from the SDM indicating the drivers seat belt status.

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