Forward Collision Warning Chime

The forward collision warning chime warns that a forward collision potential has been detected or the CCM and/or IPMA detects a forward collision warning system concern. Once the forward collision system detects a possible forward collision, the IPMA sends the HUD module the heads up flash rate message to flash the forward collision warning and the forward collision warning message request through the GWM to sound a 0.25-second chime tone 12 times to the IPC.

The forward collision warning system and chime can be disabled or turned off using the message center. When MyKey® is in use, the driver cannot configure the forward collision warning system or chime off. When the driver disables the forward collision warning chime, the IPMA sends the IPC the forward collision chime request through the GWM to sound a 0.25-second chime tone 12 times at 50% volume. The forward collision warning chime and confirmation chime are both sounded through the front speakers.

The IPC receives the forward collision warning message request and the forward collision chime request from the GWM over the HS-CAN3.

The GWM receives the forward collision warning message request and the forward collision chime request from the IPMA over the HS-CAN2.

When a chime request is received, the IPC sends the IPC chime request message to the ACM or the audio DSP to sound the chime.
