Sunroof / Moonroof: Description and Operation

System Outline

Current is always applied from the S/ROOF fuse to TERMINAL 5 of the sliding roof control ECU. With the ignition SW turned on, the current from the ECU-IG fuse flows to TERMINAL 8 of the sliding roof control ECU.

1. Sliding Roof Open/Close Operation
For sliding roof operation, there are sliding roof control switches: "Slide open/tilt up"; and "Slide close/tilt down." 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 43 seconds elapse after the ignition SW is turned from ON to OFF or until the driver's or passenger's door is opened, 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 sliding roof control ECU detects jamming of the sliding roof by foreign material, if occurred, from abnormal motor speed signal and reverses the sliding roof operation.

- When the battery terminal or fuse is disconnected, the roof position has to be reset to its initial position by the sliding roof control SW in accordance with the following procedure:

1. Reconnect the battery terminal or fuse.
2. Turn ON the ignition switch.
3. Operate the sliding roof control SW to open the roof halfway or more.
4. Then operate the sliding roof control SW to fully close the roof.
Do not release the switch for at least 2 seconds after the roof is fully closed.
