Lane Keeping Alert Warning Chime

The lane keeping alert warning chime alerts the driver the driver's hands are no longer on the steering wheel. The IPC receives the lane keeping system hands off display message from the BCM over the MS-CAN. The BCM receives the lane keeping system hands off display message from the IPMA 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.
