SUNROOF

76-6-10 DESCRIPTION AND OPERATION

Rear sunroof rear switch

The rear sunroof rear switch is located in the roof console in front of the rear sunroof.  It controls the rear sunroof 
motor via the sunroof ECU.

The rear sunroof front switch supplies an earth signal through the rear sunroof isolation switch to the sunroof ECU.  
The pin at the ECU that receives the earth signal determines whether ECU causes the sunroof to open or close.

TestBook cannot monitor the state of the rear sunroof rear switch.

The following table lists the values which can be measured at the listed ECU pins when the conditions outlined are
