General Information

The sunroof control module determines the direction of the sunroof actuator based on inputs received from the sunroof switch. Voltage is applied to the sunroof control module under one of the following conditions:
^ The ignition switch is in RUN.
^ The ignition switch is in ACCY.
^ The Retained Accessory Power (RAP) is active. The voltage applied to the sunroof control module enables power sunroof operation. The direction of the sunroof actuator changes by reversing the polarity of the voltage going to the actuator. The sunroof control module remembers the sunroof position when the ignition is turned to OFF.

The contacts on the sunroof actuator limit switch must close before the following actions occur:
^ The sunroof vents.
^ The sunroof slides.
^ The sunroof opens.

The limit switch signals to the sunroof control module that the glass is parallel to the sheet metal.

The 4-way sunroof switch provides the input voltages to the sunroof control module. The following table provides the sunroof control module input terminal conditions for each switch selection.
