General Information

The sunroof module contains the logic for the opening and the closing of the sunroof based on the sunroof switch request inputs and the positions of the soft stop and vent limit switches. The sunroof actuator contains the sunroof actuator motor and the limit switches.

The sunroof module receives battery positive (B+) voltage when the ignition is in ACCY, RUN or when the Retained Assessory Power (RAP) relay is energized through the RETAINED ACCESSORY POWER circuit breaker. For more information on the RAP refer to Retained Accessory Power (RAP) Operation in Retained Accessory Power. The ground is applied constantly to the sunroof module.

The sunroof module controls sunroof motor direction by changing the polarity of the applied voltage. When the sunroof switch is placed in one of the requested positions then the sunroof module applies voltage to the sunroof actuator motor causing the sunroof to move to the proper position.
