Sunroof Motor

The sunroof system has a bi-directional motor. When the sunroof motor is not operating both circuits are at ground potential. When the sunroof motor drives the sunroof glass in the direction from the vent to closed or closed to open position, the following occurs:
^ Voltage is supplied to the sunroof motor open control circuit.
^ Ground is maintained to the sunroof motor close control circuit.

When the motor drives the sunroof glass in the direction from the open to closed or closed to vent position, the following occurs:

The sunroof module is equipped with a timer circuit which stops the operation of the sunroof motor after 10 seconds.
