Warning Chimes And Chime Characteristics

With Base AM/FM Audio System

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 chimes are all sounded through the IPC since the ACM is not on the CAN .

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 uses the following messages to control the warning chimes:

• Engine rpm data
• Driver door ajar status
• Passenger door ajar status
• Left rear door ajar status
• Right rear door ajar status
• Hood ajar status
• Liftgate ajar status
• Accessory delay
• Ignition status

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 through the GWM over the HS-CAN3 .

Without Base AM/FM Audio System

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 uses the following messages to control the warning chimes:

• Engine rpm data
• Driver door ajar status
• Passenger door ajar status
• Left rear door ajar status
• Right rear door ajar status
• Hood ajar status
• Liftgate ajar status
• Accessory delay
• Ignition status
• Audio chime status

The IPC sends the following messages to the ACM or DSP module (Harmon audio system only) control the warning chimes:

• IPC chime request
• Chime source
• Chime module power up
• Chime controls

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 through the GWM over the HS-CAN3 . 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 module power up and chime controls messages to the ACM or DSP module (Harmon audio system only) to control the chimes.

Airbag Warning Chime

The airbag secondary warning chime warns the driver that the airbag warning indicator LED is inoperative. If the IPC detects a fault with the airbag warning indicator LED during the bulb prove out, the airbag secondary warning chime sounds. If the IPC detects a fault in the airbag warning indicator when a SRS fault condition exists and the RCM has sent the IPC the airbag indicator request, the airbag secondary warning chime sounds. The airbag chime is a 0.5-second chime that sounds 5 times.

If not equipped with the base AM/FM audio system and a fault condition is detected, the IPC sends the IPC chime request message to the ACM and the DSP (Harmon audio system only) to sound the chime. The airbag secondary warning chime sounds through the front speakers.

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 in all markets.
Refer to: Seatbelt Minder Deactivating/Activating (413-01 Instrumentation, Message Center and Warning Chimes, General Procedures).

The Belt-Minder® feature is controlled by the IPC supplementing 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. The Belt-Minder® begins once the current seatbelt warning has ended and the vehicle speed has exceeded 20 km/h (12 mph) (South America) or 10 km/h (6 mph) (except South America) 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 10 km/h (6 mph) (South America) or 5 km/h (3 mph) (except South America) 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.

The Belt-Minder® turns off when the ignition is transitioned to OFF, ACC or START, or after 4.5 minutes (270 seconds) has elapsed since the first Belt-Minder® warning occurred. Whenever the vehicle is placed in REVERSE (R), the Belt-Minder® is suspended but reactivates if the driver or passenger seatbelt(s) are unbuckled and vehicle speed exceeds 10 km/h (6 mph).

For all markets except South America, an additional feature of the Belt-Minder® is the toll booth feature. The toll booth feature allows the driver or passenger to unbuckle the seatbelt for 60 seconds (10 seconds when MyKey® is in use) then re-buckle before the Belt-Minder® chime reactivates.

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 .
