Sunshade Control Unit (Motor) Input Test
NOTE: If the sunshade does not work in AUTO, or the auto reverse operation works frequently, do the sunshade calibration.
  1. Turn the ignition switch OFF.
  1. Remove the headliner.
  1. Disconnect the 10P connector (A) from the sunshade control unit/motor (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 sunshade control unit/motor.
