Message Center - System Operation and Component Description

When the conditions require the Belt-Minder® chime, the IPC sends the IPC chime request message to the ACM and the audio DSP module over the HS-CAN3 to sound the chime.

Blind Spot Information System (BLIS®)/Cross Traffic Alert (CTA) Warning Chime

The Blind Spot Information System (BLIS®)/Cross Traffic Alert (CTA) warning chime sounds to alert the driver that a vehicle has been detected or that there is a system fault. The Blind Spot Information System (BLIS®)/Cross Traffic Alert (CTA) warning chime sounds a 0.25-second chime continuously through the rear speakers until the request is ended.

The IPC receives the Cross Traffic Alert (CTA) left status, Cross Traffic Alert (CTA) right status, side obstacle sensor status-left and the side obstacle sensor status-right request messages from the GWM over the HS-CAN3.

The GWM receives the Cross Traffic Alert (CTA) left status, the Cross Traffic Alert (CTA) the right status, side obstacle sensor status-left and the side obstacle sensor status-right request messages from the SODL and SODR over the MS-CAN.

When a chime request is received, the IPC sends the IPC chime request message to the ACM and DSP module over the HS-CAN3 to sound the chime.

Door Ajar Warning Chime

The door ajar warning chime warns that a door is ajar. When a door becomes ajar while the ignition is in RUN with vehicle speed greater than 5 km/h (3 mph), the IPC displays the appropriate door ajar warning message and sounds a single chime tone through the front speakers for each door opened. The door ajar chime only sounds once for each time the door is opened, and only repeats the chime if the door is closed then reopened.

The IPC receives the driver door ajar status and passenger door ajar status from the GWM over the HS-CAN3. The GWM receives the driver door ajar status and passenger door ajar status from the BCM over the HS-CAN1.

When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP module over the HS-CAN3 to sound the chime.

Forward Collision Warning Chime

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

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 disable the forward collision warning system. When the driver disables the forward collision warning chime, the CCM 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 CCM over the HS-CAN2.

When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP module over the HS-CAN3 to sound the chime.

Headlamps On Warning Chime

The headlamps on warning chime warns the headlamps are on when exiting the vehicle. When the driver exits the vehicle with the driver door ajar, the headlamp switch is in the PARK or HEADLAMP position and the ignition is OFF, the BCM sends the headlamp switch status message to the IPC through the GWM to sound a 1-second chime tone continuously through the front speakers.

The IPC receives the headlamp on warning chime message from the GWM over the HS-CAN3.

The GWM receives the headlamp on warning chime message from the BCM over the HS-CAN1.
