Park enable signal circuit  | B0005  | 1  | 1  | --  | 
1. Will cause symptom related to SEO device.  | ||||
The park enable signal circuit is a voltage output from the body control module (BCM) only when the vehicle is not in the PARK position. This circuit is for the control of SEO devices.
| • | The system voltage is between 9-16 volts. | 
| • | The DTC can only set when the output is actively being requested by the module. | 
The DTC will set only when the module requests the output and there is a short to ground.
The module output driver will be shut down and not supply voltage to the circuit.
| • | The current DTC will clear when the module request for the output is removed or 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 the test lamp does illuminate, 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. | 
Important: Always perform the Diagnostic Repair Verification after completing the diagnostic procedure.
