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, vehicle speed and transmission shift mode display messaged inputs to control the ignition-engine on warning chime.
The IPC receives the driver door ajar status, vehicle speed and transmission shift mode display messages from the GWM over the HS-CAN3.
The GWM receives the driver door ajar status message from the BCM over the HS-CAN1.
The GWM receives the vehicle speed and transmission gear display messages from the PCM over the HS-CAN1.
When a chime request is received, the IPC sends the IPC chime request message to the ACM or the DSP (with Revel audio system) to sound the chime.
