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 through 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 HS-CAN3.
The GWM receives the key-in-ignition status from the BCM over the HS-CAN1.
When a chime request is received, the IPC sends the IPC chime request message to the ACM or the audio DSP to sound the chime.
