If the sunshade does not work in AUTO, or reverse frequently (pinch detection),
do the sunshade calibration
before proceeding with the input test.
-
Turn the ignition switch to LOCK (0).
-
-
Disconnect the 10P connector (A) from the sunshade control unit (B).
-
Inspect the connector and socket terminals to be sure they are all making good contact.
-
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.
