Shift To Park Message Display

Refer to Component Description - PARK POSITION DETECT SWITCH .

The IPC displays a shift to park message when the vehicle is turned OFF with the shifter out of the PARK (P) position (with IA). The IPC monitors the park position detect switch input through the park detect signal, or input circuit. The IPC provides the transmission park status to the BCM. When the selector lever is out of the PARK (P) position, the park detect switch closes to ground and the IPC detects the reference voltage pulled low. The IPC sends a park status message to the BCM, indicating that the selector lever is not in PARK (P). The IPC monitors the ignition state and when the ignition is OFF with the selector lever out of PARK (P), the IPC displays the shift to park message.
