Circuit Description
When the body control module (PZM) receives a serial data message from the powertrain control module (PCM) that the transaxle is in PARK, the PZM grounds the PARK relay control circuit. The PZM monitors this output and determines the actual voltage.
Conditions for Setting the DTC
The body control module (PZM) determines that the PARK relay control circuit voltage is approximately equal to ground.
Action Taken When the DTC Sets
The body control module (PZM) continues to command the requested state until the state is achieved or until the request changes.
Conditions for Clearing the DTC
The body control module (PZM) determines that the PARK relay control circuit voltage is greater than ground for one monitoring cycle.
