Sunroof / Moonroof: Description and Operation

System Outline

Current is always applied from the POWER fuse to TERMINAL 10 of the moonroof control ECU and motor. With the ignition SW turned on, the current flows to TERMINAL 9 of the moonroof control ECU and motor.

1. Moonroof Open/Close Operation
For moonroof operation, there are moonroof control switches: "Slide open/tilt down "; and "Slide close/tilt up". When a switch is pressed and held down for a certain period of time, one touch automatic operation takes place in accordance with the function of the switch.

2. Key-Off Operation
Roof remains operable - until about 45 seconds elapse after the ignition SW is turned from ON to OFF or until the driver's seat door is opened and closed, whichever first occurs.

However, if an overload reverse operation was going on at that time, the key off operation continues until it comes to an end.

3. Overload Reverse Operation
The moonroof control ECU and motor detects jamming of the moonroof by foreign material, if occurred, from abnormal motor speed signal and reverses the moonroof operation.

4. Deflector Control Function
When the roof is slid fully open, the moonroof control ECU and motor automatically adjusts the height of deflector in accordance with the vehicle cruising speed.

- When the battery terminal or fuse is disconnected, the roof position has to be reset to its initial position by the moonroof control SW in accordance with the following procedure:
1. Reconnect the battery terminal or fuse.
2. Turn ON the ignition switch.
3. Operate the moonroof control SW to open the roof halfway or more.
4. Then operate the moonroof control SW to fully close the roof.
Do not release the switch for at least one second after the roof is fully closed.
