## Sunroof Control Unit Input Test

## KK, KU and KT models

1. | Remove the headliner.

2. | Disconnect the 5P connector (A) from the sunroof control unit (B).

3. | 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, replace the sunroof control unit.
