Power Sunroof Inoperative

POWER SUNROOF INOPERATIVE

DIAGNOSTIC AIDS
- The retained accessory power (RAP) relay supplies power to the SUNRF fuse. If the SUNRF fuse is open and the RAP system is operating properly, the fault could be a short to ground in either of the sunroof motor control circuits. A short to ground in either of these circuits would open the SUNRF fuse.
- If voltage is not measured on the sunroof switch open signal or sunroof switch open vent signal circuits, the fault could be in the accessory voltage or sunroof control module ground circuits. If the sunroof control module is not being powered, neither will the sunroof switch signal circuits.

TEST DESCRIPTION

Steps 1 - 10:

Steps 11 - 21:

Steps 22 - 26:

3. This step tests to determine if the RAP relay is providing power to the SUNRF fuse.
4. This step is used to determine the correct diagnostic path. The path depends on if the sunroof is inoperative and in the open position, or if the sunroof is inoperative and in the closed position.
5. This step tests the sunroof switch open switch.
6. This step tests the sunroof switch close switch.
11. This step tests the sunroof control module for an internal open.
13. This step tests the sunroof control module for an internal short to battery positive voltage.
14. This step tests the sunroof motor for an open.
