Transmission Not In Park (Shift To Park)

The message center provides a shift to park message to inform the driver the vehicle is not in P under 2 sets of conditions. First, the IPC displays the shift to park message if the selector lever is not in P, the ignition is OFF and the driver door is open or ajar. Second, the message center displays the shift to park message if the selector lever is not in P, the ignition is ON or in ACC, the driver door is open or ajar and the brake pedal is not applied with vehicle speed less than 5 km/h (3 mph). The IPC uses multiple messages to control the shift to park message.

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

The GWM receives the transmission gear display and vehicle speed messages from the PCM 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 P along with the transmission gear display message.
