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.
