Ignition-Engine On Warning Chime

The ignition-engine on chime informs the driver they are exiting the vehicle when the ignition has been left on (engine off) or the engine is running. When the driver exits the vehicle with the ignition on or with the engine running, the ignition-engine on warning chime sounds five 1-second chime tones. The ignition-engine on warning chime sounds through the front speakers. The IPC  uses driver door ajar status, power pack status and transmission gear display messaged inputs to control the ignition-engine on warning chime.

The IPC  receives the driver door ajar status, power pack status and transmission gear display messages from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM  receives the driver door ajar status message from the BCM  over the High Speed Controller Area Network 1 (HS1-CAN).

The GWM  receives the power pack status and transmission gear display messages from the PCM  over the High Speed Controller Area Network 1 (HS1-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.
