Warning Chimes
Warning Chimes And Chime Characteristics
The IPC uses multiple network messages to control the overall warning chime arbitrator. The IPC arbitrates and controls all chimes regardless if they are sounded through the audio system or the IPC. The warning chimes all sound through the audio system except for the turn signal tick-tock chime, which is sounded through the IPC. In the event of an audio system fault, the IPC sounds all chimes. The audio system has the ability to sound up to 2 chimes at a time while the IPC can only sound a single chime at a time.
The warning chimes use volume, chime frequency, length of time the chime sounds, length of off time between chime tones, decay of the chime tone and the number of chime tones to identify which chime is sounding. Most warning chimes have unique characteristics, however, there are chimes that do sound the same. The chime characteristics are defined by the different chime types:
- Information
- Soft-warning
- Hard-warning
- Tick-tock (on-off)
The IPC receives the engine rpm data from the PCM and all door, hood and liftgate ajar status, accessory delay and ignition status messages from the BCM over the HS-CAN1. The IPC receives the audio chime status message from the ACM over the HS-CAN3.
The IPC sends the IPC chime request, chime source, chime power up and chime controls messages to the DSP module to control the chimes.
Warning Chimes
Active Park Assist
The active park assist system uses informational and instructional messages displayed in the FDIM to direct the driver's interaction with the system. The active park assist system chimes alert or to draw the driver's attention to the requested actions as displayed in the FDIM messages. The active park assist chime sounds through the front speakers.
The IPC receives the active park assist message display message from the GWM over the HS-CAN3.
The GWM receives the active park assist message display message from the PAM over the HS-CAN1.
The IPC then sends the IPC chime request message to the DSP module to sound the chime.
Adaptive Cruise Control Warning
The adaptive cruise control warning chime supplements the message center displays to draw the driver's attention to the need to intervene and take control of the vehicle. There are 2 levels of chime output (high priority and low priority) based upon the nature and urgency of the warning. The adaptive cruise control warning chime sounds through the front speakers. The audio system sounds the appropriate warning chime when it receives the adaptive cruise control warning request message from the CCM.
The low priority adaptive cruise control warning chime is a single-tone, 1-second chime that sounds to alert the driver the adaptive cruise control system has shut itself off due to low vehicle speed (approximately 32 km/h [20 mph]) and the driver needs to intervene if further braking is required or to resume the adaptive cruise control operation.
The high priority adaptive cruise control warning chime is a 0.25-second chime that sounds 12 times. The chime alerts the driver the vehicle is approaching the vehicle ahead at a faster rate than the adaptive cruise control system can brake the vehicle and the driver needs to apply the brakes to slow the vehicle down.
The IPC receives the cruise control and adaptive cruise control warning request messages from the GWM over the HS-CAN3.
The GWM receives the adaptive cruise control warning request message from the CCM through a private CAN to the IPMA over the HS-CAN2.
The GWM receives the cruise control status message from the PCM over the HS-CAN1.
When a chime request is received, the IPC sends the IPC chime request message to the DSP module to sound the chime.
Backup Warning (Except North America)
The reverse warning chime warns the vehicle is in reverse. When the transmission is in reverse, the PCM sends the gear lever position message to the GWM over the HS-CAN1. The GWM sends the gear lever position status message to the IPC over the HS-CAN3 to sound a 1-second chime tone continuously through the front speakers.
Belt-Minder® Feature
The Belt-Minder® is configurable on or off. Refer to: Seatbelt Minder Deactivating/Activating .(413-01 Instrumentation, Message Center and Warning Chimes, General Procedures).
The Belt-Minder® feature supplements the current seatbelt warning function and is enabled after the current seatbelt warning is complete. The Belt-Minder® reminds the driver that the driver or front passenger seatbelt is unbuckled by intermittently sounding a chime and simultaneously illuminating the seatbelt warning indicator through the front speakers. The Belt-Minder® begins once the current seatbelt warning has ended and the vehicle speed has exceeded 10 km/h (6 mph) with the driver or front passenger seatbelt unbuckled. While activated, the Belt-Minder® chime provides a series of chimes/seatbelt warning indicator flash sequences.
If the vehicle speed drops below 5 km/h (3 mph) once the Belt-Minder® chime has activated, the chime turns off and the seatbelt warning indicator remains on. When the vehicle speed exceeds 10 km/h (6 mph) again, the Belt-Minder® chime resumes.
When MyKey® is in use, the driver cannot configure the Belt-Minder® off. Once the Belt-Minder® is activated, the Belt-Minder® continues to chime periodically (does not time out after 5 minutes) and the audio system is muted until the driver and passenger seatbelts are fastened.
To control the Belt-Minder®, the IPC receives the vehicle speed, gear lever position, driver and passenger seatbelt buckle status and front passenger detect status messages from the GWM over the HS-CAN3.
The GWM receives the vehicle speed and gear lever position messages from the PCM over the HS-CAN1.

CTA Warning
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 active park assist chime sounds through the rear speakers.
The IPC receives the CTA left status, the 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 CTA left status and the side obstacle sensor status-left messages from the SODL over the MS-CAN.
The GWM receives the CTA right status and the side obstacle sensor status-right request messages from the SODR over the MS-CAN.
When a chime request is received, the IPC sends the IPC chime request message to the DSP module to sound the chime.
Door Ajar Warning
The door ajar warning chime warns that a door, hood or liftgate is ajar and sounds the chime through the front speakers. When a door, hood or liftgate 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 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, passenger door ajar status, left rear door ajar status, right rear door ajar status, hood ajar status or liftgate ajar status message from the GWM over the HS-CAN3.

When a chime request is received, the IPC sends the IPC chime request message to the DSP module to sound the chime.
Forward Collision Warning
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 IPC and the HUD module the forward collision warning visible alert request to flash the forward collision warning, and the forward collision chime 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 configure the forward collision warning system or chime off. 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.
