Park/Neutral Position Switch

RANGE PARK/REVERSE/NEUTRAL/OVERDRIVE/DRIVE 3/DRIVE 2/LOW/INVALID:
The scan tool displays the decoded position of the Park/Neutral Position switch PRNDL inputs. This information is then sent by Class 2 serial data to the Instrument Panel Cluster (IPC) to be displayed to the operator on the IPC. If a valid combination of inputs is not seen by the PCM, Invalid will be displayed.
