Key-In-Ignition Warning Chime (Without Passive Key)

The key-in-ignition warning chime warns the key is still in the ignition lock cylinder or the ignition is in ACC when the driver door is ajar. The key-in-ignition warning chime sounds repetitive 0.5-second chime tones from the front speakers until either the key is removed from the lock cylinder, the ignition is in RUN or the driver door is closed.

The IPC  receives the key-in-ignition status from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM  receives the key-in-ignition status from the BCM  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.
