17. Disconnecting the connector to the sunroof opening position switch (SOPS) (limit switches) and shorting the sunroof limit switch vent signal circuit to the sunroof limit switch low reference circuit, will simulate that the glass is in a position other than closed or full open position. This will allow any request from the sunroof switch to supply an output to drive the sunroof motor/actuator.
18. Checking the sunroof motor/actuator open and close output circuits, when idle both should be at ground potential.
