CTA Warning Chime

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

The IPC receives the CTA left status, the CTA right status, side obstacle detect status-left and the side obstacle detect status-right request messages from the GWM over the HS-CAN3.

The GWM receives the CTA left status and the side obstacle detect status-left messages from the SODL over the MS-CAN.

The GWM receives the CTA right status and the side obstacle detect status-right request messages from the SODR over the MS-CAN.

If not equipped with the base AM/FM audio system and a chime request is received, the IPC sends the IPC chime request message to the ACM or DSP (Harmon audio system only) to sound the chime through the rear speakers.
