Conditions for Setting the DTC
The DTC will set when the module requests the output and there is a short to ground.
Action Taken When the DTC Sets
The module output driver will be shut down and not supply voltage to the circuit.
Conditions for Clearing the DTC
* The current DTC will go to history when a malfunction is no longer present.
* The BCM clears the history DTC when a current DTC is not detected in 50 ignition cycles.

Circuit/System Testing
1. Ignition OFF, disconnect the park enable PCB relay.
2. Connect a test lamp between the park enable signal circuit and battery positive voltage.
3. Ignition ON, transmission in PARK, verify the test lamp does not illuminate.
锟斤拷 If the test lamp illuminates, test for a short to ground on the park enable signal circuit. If the circuit tests normal and the DTC is current,
replace the BCM.
4. If the circuit tests normal and the DTC is current, test or replace the park enable PCB relay.
