Sunroof / Moonroof Module: Testing and Inspection
Moonroof Control Unit Input Test
Before troubleshooting the moonroof circuit, troubleshoot the multiplex integrated control system using B-CAN System Diagnosis Test Mode A.
If the moonroof works OK manually, but will not work in AUTO, or reverse frequently (pinch detection), do the moonroof calibration before proceeding
with the input test.
1. Turn the ignition switch OFF.
2. Remove the headliner.
3. Disconnect the 10P 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 control unit 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, the control unit must be faulty; replace the control unit.
