8. Using a jumper wire to jump between the sunroof limit switch vent signal circuit and the sunroof limit switch low reference circuit, will simulate that the glass is in a position other than full vent or full open position. This will allow any request from the sunroof switch to supply an output to drive the sunroof motor for testing the status of the limit switches.
12. Checking the sunroof motor open and close output circuits, both should be at ground potential when idle.
