B255D-DECKLID OPEN POSITION SENSOR CIRCUIT PERFORMANCE





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
With the Ignition Switch in the on position and the Power Top Control Module (PTCM) is awake.

- Set Condition:
This code will set when there is a timeout in the roof sequence because the Decklid Position Sensor is stuck active or shorted to battery for 500 ms.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase all PTCM DTC's.
Try to operate the Power Top Switch.
Wait 30 seconds.
With the scan tool, read all PTCM DTC's.
Does the scan tool display this DTC as active?

Yes

- Go to 2

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

2. (Q975) DECKLID POSITION SIGNAL CIRCUIT SHORTED TO VOLTAGE




Turn the ignition off.
Disconnect the PTCM C1 harness connector.
Disconnect the Decklid Position Sensor harness connector.
Turn the ignition on.
Measure the voltage of the (Q975) Decklid Position Signal circuit in the Decklid Position Sensor harness connector.
Is there any voltage present?

Yes

- Repair the (Q975) Decklid Position Signal circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go to 3

3. (Q975) DECKLID POSITION SIGNAL CIRCUIT OPEN




Turn the ignition off.
Measure the resistance of the (Q975) Decklid Position Signal circuit between the PTCM C1 harness connector and the Decklid Position Sensor harness connector.
Does the ohm meter read open circuit?

Yes

- Repair the (Q975) Decklid Position Signal circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go to 4

4. (Q969) DECKLID POSITION RETURN CIRCUIT SHORTED TO VOLTAGE




Turn the ignition on.
Measure the voltage of the (Q969) Decklid Position Return circuit in the Decklid Position Sensor harness connector.
Is there any voltage present?

Yes

- Repair the (Q969) Decklid Position Return circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go to 5

5. (Q969) DECKLID POSITION RETURN CIRCUIT OPEN




Turn the ignition off.
Measure the resistance of the (Q969) Decklid Position Return circuit between the PTCM C1 harness connector and the Decklid Position Sensor harness connector.
Does the ohm meter read open circuit?

Yes

- Repair the (Q969) Decklid Position Return circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Replace the Power Top Control Module (PTCM).
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test
