Front sunroof motor and microswitch

Front sunroof motor and microswitch

The front sunroof motor is located within the front sunroof assembly. The sunroof ECU controls the front sunroof motor.

The sunroof ECU determines the direction the sunroof motor runs. A battery signal to one side of the motor and an earth to the other side of the motor causes the motor to turn in one direction, reversing the polarity through the same pins causes the motor to turn in the opposite direction.

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

Signal values (connector connected)
