The numbers below refer to the steps on the diagnostic table.
4. If the sunroof switch open signal circuit is jumpered first, this may cause the window to express open. Jumpering the sunroof switch close signal circuit will halt the express open feature. To close the sunroof glass the sunroof switch close signal circuit will need to be jumpered again, and maintained to continue to close the sunroof glass.
17. Disconnecting the connector to the sunroof opening position switch (SOPS), and shorting the SOPS vent signal circuit to the SOPS 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 motor for testing the status of the SOPS.
18. Checking the sunroof motor open and close output circuits, when idle both should be at ground potential.
