Warning Chime Characteristics
The warning chimes use volume, chime frequency, length of time the chime sounds, 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:
Active Park Assist Chime
The active park assist system uses informational and instructional messages displayed in the FCDIM 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 FCDIM messages. The active park assist chime sounds through the front speakers.
The IPC receives the parking aid chime request from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).
The GWM receives the parking aid chime request from the Parking Aid Module (PAM) over the High Speed Controller Area Network 1 (HS1-CAN).
The IPC then sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
Adaptive Cruise Control Warning Chime
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 (high priority chime) or cruise control status (low priority chime) message from the Cruise Control Module (C-CM).
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 status and the adaptive cruise control warning request messages from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).
The GWM receives the cruise control status message from the PCM over the High Speed Controller Area Network 1 (HS1-CAN).
The GWM receives the adaptive cruise control warning request message from the Cruise Control Module (C-CM) over the High Speed Controller Area Network 2 (HS2-CAN).
When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
Air Bag Secondary Warning Chime
The air bag secondary warning chime warns the air bag warning indicator LED is inoperative. The air bag secondary warning chime sounds through the front speakers. If the IPC detects a fault with the air bag warning indicator LED during the bulb prove out, the air bag secondary warning chime sounds. If the IPC detects a fault in the air bag warning indicator when a SRS fault condition exists and the RCM has sent the IPC the air bag indicator request, the air bag secondary warning chime sounds. The air bag chime is a 0.5-second chime that sounds 5 times.
When a fault condition is detected, the IPC sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
Belt-Minder® Feature
NOTE: Whenever the vehicle is operated using MyKey®, the IPC enables the Belt-Minder®.
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 safety belt warning function and is enabled after the current safety belt warning is complete. The Belt-Minder® reminds the driver the driver or front passenger safety belt is unbuckled by intermittently sounding a chime and simultaneously illuminating the safety belt warning indicator through the front speakers. The Belt-Minder® begins once the current safety belt warning has ended and the vehicle speed has exceeded 10 km/h (6 mph) with the driver or front passenger safety belt unbuckled. While activated, the Belt-Minder® chime provides a series of chimes/safety belt 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 safety belt 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 safety belts are fastened.
To control the Belt-Minder®, the IPC receives the vehicle speed, gear lever position, driver and passenger safety belt buckle status and front passenger detect status messages from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).
The GWM receives the vehicle speed and gear lever position messages from the PCM over the High Speed Controller Area Network 1 (HS1-CAN).
The IPC receives the driver and passenger safety belt status messages from the RCM over the High Speed Controller Area Network 2 (HS2-CAN).
When the conditions require the Belt-Minder® chime, the IPC sends the IPC chime request message to the ACM and the audio DSP 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 until the request is ended. The active park assist chime sounds through the rear speakers.
The IPC 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 GWM over the High Speed Controller Area Network 3 (HS3-CAN).
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 Medium Speed Controller Area Network (MS-CAN).
When a chime request is received, the IPC sends the IPC chime request message to the ACM and DSP to sound the chime.
Door Ajar Warning Chime
The door ajar warning chime warns that a door is ajar and sounds the chime through the front speakers. 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 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.
