PRNDL Not In Park Warning Chime

The IPC provides a PRNDL not in park warning chime that sounds along with the transmission not in park message center display to inform the driver the vehicle is not in PARK (P). The IPC displays the shift to park message and the PRNDL not in park warning chime sounds three 0.5-second chime tones through the front speakers if the selector lever is not in PARK (P), the ignition is OFF and the driver door is open or ajar. The IPC requires the transmission gear display mode, brake pedal applied, vehicle speed, driver door ajar and ignition status to control the PRNDL not in park warning chime.

The IPC receives all required messages from the GWM over the HS-CAN3.

The GWM receives the brake pedal applied, transmission gear display mode and vehicle speed messages from the PCM over the HS-CAN1.

The GWM receives the driver door ajar status and ignition status message from the BCM over the HS-CAN1.

When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP module to sound the chime.
