Safety Belt Warning Chime

The safety belt warning chime warns that the safety belt is not fastened. The safety belt warning chime sounds through the front speakers a repetitive chime tone for 6 seconds when the driver safety belt is not fastened and the ignition is transitioned from OFF or ACC to ON or START. The safety belt warning chime stops sounding when the safety belt is fastened, when the ignition is transitioned from ON or START to OFF or ACC, or when the chime has sounded for 6 seconds. The IPC receives the driver and passenge safety belt status messages from the BCM over the MS-CAN. The BCM receives the safety belt status messages from the RCM over the HS-CAN.

When a chime request is received, the IPC sends the IPC chime request message to the ACM (without Sony audio system) and audio DSP (with Sony audio system) to sound the chime.
