- 2Push out the switch from behind the instrument panel, then disconnect the 6-P connector to remove the switch.

- 3Check for continuity between the BLK terminal and body ground. If no continuity, check for poor ground (LHD: G301, 401 RHD: G201, 401).
- 4Check for continuity between the WHT/GRN terminal and body ground with the ignition switch OFF. There should be continuity when the sunroof is closed. There should be no continuity when the sunroof is opened.
- 5Check for voltage between the WHT/GRN terminal and the BLK terminal with the ignition switch ON. There should be battery voltage when the sunroof is opened.
- 6Check for voltage between the GRN terminal and BLK terminal with the ignition switch ON. There should be battery voltage when the sunroof closed.
