BLIS ®/ CTA Chime

The BLIS ®/ CTA warning chime sounds to alert the driver that a vehicle has been detected or there is a system fault. The BLIS ®/ CTA warning chime sounds a 0.25-second chime continuously until the request is ended. The BLIS ®/ CTA chime sounds through the rear speakers.

The IPC receives the BLIS ® status from the BCM over the MS-CAN. The BCM receives the BLIS ® status from the SODL and SODR over the Extended MS-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.
