Glass Roof Sunshade Control Unit (Motor) Input Test

If the sunshade does not work in AUTO, or reverse frequently (pinch detection), do the sunshade calibration before proceeding with the input test.
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the 10P connector (A) from the sunshade control unit (B).
  1. 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 .
  1. 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, the control unit must be faulty; replace the control unit.
