The power sunroof system consists of the following components:

The power sunroof will operate with the ignition switch turned to Accessory or RUN. Once the ignition switch is turned to OFF from the RUN position the sunroof system will continue to operate until any door is open or when the Retained Accessory Power (RAP) has timed out. For a description and operation of the RAP operation, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power.

Use the rocker type sunroof switch, located in the front center of the headliner, to command the sunroof glass to :

Pressing the sunroof switch rearward, the sunroof glass will slide from:

Pressing the sunroof switch forward, the sunroof glass will slide from:

To open the power sunroof glass to the vent position from the closed position press and hold the sunroof switch forward. This will apply the sunroof switch low reference to the sunroof switch close signal circuit (ignition voltage reference) input to drop to 0 volts. As long as the sunroof module sees a constant input request from the sunroof switch close signal circuit (0 volts), the sunroof module will continue to control the sunroof motor to raise the rear of the sunroof glass upward to the full vent position. The sunroof glass will stop (hard stop) at the full vent position. To stop the sunroof glass in a position other than the full vent position, release the sunroof switch when the sunroof glass reaches the desired vent position. The sunshade will have to manual slid open.

To close the power sunroof glass from the vent position, momentarily toggle or pull the sunroof switch rearward. This will apply the sunroof switch low reference circuit to the sunroof switch open signal circuit (ignition voltage reference) input to drop to 0 volts. This momentary input simulates an express open operation to the closed position. The sunroof module will control the sunroof motor to lower (express close) the rear of the glass (downward) to the closed position. The sunroof glass will stop (soft stop) at the closed position based on the input from the limit switch. The sunshade will have to be manually slid closed.

The express open will work only with the sunroof glass in between the closed and partially open positions. To express open the power sunroof, momentarily toggle or pull the sunroof switch rearward. This will apply the sunroof switch low reference circuit to the sunroof switch signal open signal circuit (ignition voltage reference) input to drop to 0 volts momentarily. The momentary 0 volts input to the sunroof module indicates an express open request. The sunroof module will control the sunroof motor to lower the rear of the glass slightly, then begin to automatically slide (express open) between the roof and headliner, allowing the wind deflector to raise upward. The sunroof glass will stop (hard stop) at the full open position. As the sunroof glass expresses open so will the sunshade. To stop the sunroof glass in a desired position other than to the express open position, press the sunroof switch again in either direction to stop the movement.

To close the power sunroof glass from the open position is the same as to opening the sunroof glass to the vent position. Press and hold the sunroof switch forward portion. This will apply the sunroof switch low reference circuit to the sunroof switch close signal circuit (ignition voltage reference) input to drop to 0 volts. As long as the sunroof module sees a constant input request from the sunroof switch close signal circuit (0 volts), the sunroof module will control the sunroof motor to slide the sunroof glass to the closed position. The sunroof glass will stop (soft stop) at the closed position based on the input from the limit switch. The sunshade will have to be manually slide closed.

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:

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.

The sunroof limit switch tracks when the sunroof glass reaches the flush closed position. Once the limit switch closes, the sunroof limit switch low reference circuit will be applied to the sunroof limit switch soft stop signal circuit (ignition voltage reference), pulling it to 0 volts. The sunroof module sensing this input will control and stop the voltage output to the sunroof motor, soft stopping at the flush closed position.
