Sunroof / Moonroof Switch: Description and Operation
SUNROOF OPENING POSITION SWITCH/SUNROOF LIMIT SWITCHES
The sunroof limit switches within the sunroof opening position switch, track the position of the glass through 2 limit switches:
^
Soft Stop limit
^
Vent Stop limit
The sunroof control module monitors the limit switches and based on the inputs determines the position of the sunroof glass. As a limit switch closes, the
5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module understands the position of the sunroof glass based on the different input combinations from the sunroof limit switch range
switch circuit and the sunroof limit switch soft stop signal circuit inputs.
