Component Tests and General Diagnostics

Moonroof Control Unit Input Test

NOTE:

- SRS components are located in this area. Review the SRS component locations Locations, and precautions and procedures Service Precautions before doing repairs or servicing.
- If the moonroof works OK manually, but will not work in AUTO, or reverses frequently (obstacle detection), reset the moonroof before proceeding with the input test.

1. Turn the ignition switch to LOCK (0).

2. Remove the headliner.

3. Disconnect the 14P connector (A) from the moonroof control unit/motor (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, do the following input tests:

- 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 do the following input tests:

- 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. If the problem is related to the key-off operation, go to the driver's MICU input test.
