System Outline

Current is applied at all times from the POWER fuse to TERMINAL 10 of the moon roof control ECU and motor. When the ignition SW is turned on, current flows to TERMINAL 9 of the moon roof control ECU and motor.

1. Moon Roof Open/Close Operation 

   The moon roof can be operated via the moon roof 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, the one touch automatic operation takes over according to the function of the switch.

2. Key-Off Operation 

   After the ignition SW has been turned from ON to OFF the roof remains operable for about 45 seconds or until the driver door is opened and closed, whichever occurs first.

   However, if an overload reverse operation was going on at that time, the key-off operation will continue until it completes.

3. Overload Reverse Operation 

   The moon roof control ECU and motor uses abnormal motor speed signals to detect if any foreign matter is jamming the moon roof and it will then reverse the moon roof operation.

4. Deflector Control Function 

   When the roof is fully open, the moon roof control ECU and motor automatically adjusts the height of deflector in accordance with the vehicle cruising speed.

   * If the battery terminal or fuse is disconnected, the roof position has to be reset to its initial position using the moon roof control SW and the following procedure:

   1. Reconnect the battery terminal or fuse.
   2. Turn ON the ignition switch.
   3. Operate the moon roof control SW to open the roof halfway or more.
   4. Then operate the moon roof control SW to fully close the roof.

   Do not release the switch for at least one second after the roof is fully closed.
