5. Using a 12-volt test light, connect one end to the (A959) Fused B(+) circuit and the other to the (Z908) Ground in the PSD Module 6 way connector.

NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test tight illuminate brightly?

Yes

- Go To 5

No

- Repair the open in the (A959) Fused B(+) circuit or the (Z908) Ground circuit.

5. CHECK THE SLIDING DOOR POSITION SENSOR 1 SIGNAL







1. Re-connect the PSD Module C1 harness connector to the module.
2. Turn the ignition on.
3. With the scan tool, monitor the Position Sensor 1 state.
4. Connect a jumper wire to the Door Position Sensor 1 Signal terminal in the PSDM C2 (component side) connection.
5. Momentarily touch and release the other side of the jumper to the Door Position Sensor Return terminal in the PSDM C2 (component side) connection several times and observe the Position Sensor 1 states on the scan tool.

Does the state of the position sensor change each time the jumper is connected and then released?

Yes

- Go To 6

No

- Replace the Power Sliding Door Module in accordance with the Service Information.
- Perform the Power Sliding Door Learn Cycle procedure. Programming and Relearning
- Perform the BODY VERIFICATION TEST. Body Verification Test
