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 fifteen 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 closed. If the ignition is OFF, the selector lever is not in PARK (P) and the driver door is open or ajar the PRNDL not in park warning chime sounds continuous 0.5-second chime tones through the front speakers. The IPC requires the transmission gear display, 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 vehicle speed message from the PCM over the HS-CAN1.

The GWM receives the transmission gear display mode message from the PCM (gas engine) or TCM (diesel engine) over the HS-CAN1.

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

The IPC also uses the park position detect input to determine whether the vehicle is in PARK (P) along with the transmission gear display mode message.

See Park Position Detect Switch component description. Refer to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

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.
