P1d8d DescriptionThe purpose of the diagnostic is to monitor the park sense circuit from the Radio Frequency (RF) Hub. The RF Hub supplies B (+) on the park circuit to the Transmission Control Module (TCM).

If the TCM detects an open or short to ground on the park circuit, a Diagnostic Trouble Code (DTC) will set.
