Shift To Park Message Display

The IPC displays SHIFT TO PARK when the vehicle is turned off with the shifter out of the PARK (P) position on vehicles with IA. The IPC provides a reference voltage to the park detect switch through the park detect signal, or input circuit. The IPC provides the transaxle park status to the BCM.

When the selector lever is out of the PARK (P) position, the park detect switch remains open to ground leaving the reference voltage high to the IPC. The IPC sends a park status message to the BCM, indicating that the selector lever is not in PARK (P). The BCM monitors the ignition state and when the ignition is OFF with the selector lever out of PARK (P), the BCM sends the IPC an intelligent access system status message to display the SHIFT TO PARK message display.
