The body control module (BCM) supplies the park enable signal circuit voltage when the vehicle transmission is in Park.
The system voltage is between 9-16 volts.
The BCM detects there is a short to ground for greater than 5 seconds.
The BCM will not supply voltage to the circuit.
• | The current DTC will clear when the malfunction is no longer present. |
• | A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction. |

⇒ | If there is an aftermarket component wire, test the circuit terminal for a short to ground. If the circuit tests normal, replace the BCM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
