3. Disconnect the 14P connector (A) from the moonroof control unit (B).

4. Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

- If the terminals look OK, go to step 5.

5. With the connector still disconnected, make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.

- If all the input tests prove OK, go to step 6.





6. Reconnect the connector to the control unit, and make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.

- If all the input tests prove OK, go to step 7.





7. If all the input tests are OK and multiple failures are found, replace the moonroof control unit/motor assembly. If the problem is related to the key-off operation, go to the driver's MICU input test Keyless/Power Door Locks/Security System Control Unit Input Test, and passenger's MICU input test.
