System Outline

Current is applied at all times through PWR fuse to TERMINAL 3 of power main relay, With the Ignition SW turned ON, current flows through the ECU-IG fuse --> TERMINAL A-7 of the theft deterrent ECU -> TERMINAL A-6 --> TERMINAL 1 of the power main relay -> TERMINAL 2 --> to GROUND. As a result, power main relay is activated and the current to TERMINAL 3 of power main relay flows from TERMINAL 5 of relay to -> TERMINAL 6, 12 of Moon Roof Control relay.

1. SLIDE OPEN OPERATION
When the Ignition SW is turned ON and the Moon Roof Control SW is pushed to the OPEN position, a signal is input from TERMINAL 4 of Moon Roof Control SW to TERMINAL 1 of Moon Roof Control relay. Moon Roof limit SW No.1 or No.2 is ON at this time.
This activates moon roof control relay, so current flows from the PWR fuse --> TERMINAL 6 of the moon roof control relay --> TERMINAL 5 --> TERMINAL 2 of the moon roof motor --> TERMINAL 1 --> TERMINAL 4 of the moon roof control relay --> TERMINAL 11 --> to GROUND. This causes the moon roof motor to rotate to the open side, so the moon roof opens. The moon roof can be stopped before it is fully open by pressing a switch other than the open SW of the moon roof control relay

2. SLIDE CLOSE OPERATION
With the Ignition SW turned ON, the Moon Roof completely open and Moon Roof limit SW No.1 and No.2 both ON, when the Moon Roof Control SW is pushed to the close position a signal is input from TERMINAL 2 of Moon Roof Control relay.
When this occurs, the relay is activated and the current to TERMINAL 6 of Moon Roof Control relay flows from TERMINAL 4 --> TERMINAL 1of Moon Roof Motor -> TERMINAL 2 --> TERMINAL 5 of Moon Roof Control relay --> TERMINAL 11 to GROUND and rotates the Motor to close the Moon Roof while the SW is being pushed to close position.
Moon Roof limit SW No.1 turns OFF (limit SW No.2 is ON) and at 200 mm (7.9 inch) before fully CLOSED position, signal is input from TERMINAL 5 of limit SW No.1 to TERMINAL 8 of Moon Roof Control relay. This signal activates the relay and stops continuity from TERMINAL 6 of Moon Roof Control relay to TERMINAL 11. As a relay, the Moon Roof stops at this position.
To close the Moon Roof completely, pushing the Moon Roof Control SW again to the close side causes a signal to be input again to TERMINAL 2 of Moon Roof Control relay. This activates the relay and the Moon Roof will close as long as the Moon Roof Control SW is being pushed, allowing the Moon Roof to fully close.

3. TILT UP OPERATION
When the Moon Roof Control SW is pushed to TILT UP position, with the Ignition SW turned ON and the Moon Roof completely closed (Moon Roof limit SW No.2 is OFF), a signal is input from TERMINAL 6 of Moon Roof Control SW to TERMINAL 3 of Moon Roof Control relay. As a result, the relay is activated and the current to TERMINAL 6 of relay flows from TERMINAL 4 of relay --> TERMINAL 1 of Moon Roof Motor -> TERMINAL 2 --> TERMINAL 5 of relay --> TERMINAL 11 to GROUND and rotates the Motor so that Tilt up operation occurs as long as the Moon Roof Control SW is pushed ON the Tilt up side.

4. TILT DOWN OPERATION
When the Moon Roof Control SW is pushed to TILT DOWN position, with the Ignition SW turned ON and the Moon Roof tilted up (No.1 and No.2 Moon Roof limit switches are both OFF), a signal is input from TERMINAL 5 of Moon Roof Control SW to TERMINAL 7 of Moon Roof Control relay.
As a result, the relay is activated and the current to TERMINAL 6 of relay flows from TERMINAL 5 of relay -> TERMINAL 2 of Moon Roof Motor -> TERMINAL 1 --> TERMINAL 4 of relay --> TERMINAL 11 to Ground and rotates the Motor so that Tilt down operation occurs as long as the Moon Roof Control SW is pushed ON the Tilt down side. (during Tilt down, limit SW No.1 is changed from OFF to ON.)

5. KEY OFF MOON ROOF OPERATION
With the Ignition SW turned from ON to OFF, the Theft Deterrent ECU operates and current flows from POWER fuse to TERMINAL A-9 of the ECU or DOME fuse to TERMINAL B-1 of the ECU TERMINAL A-6 --> TERMINAL 1 of power main relay -> TERMINAL 2 --> to GROUNDfor about 60 Seconds. The same as normal operation, the current flows from power fuse --> TERMINAL 3 of the power main relay --> TERMINAL 5 --> TERMINAL 6 of the Moon Roof Control relay. As a result, for about 60 Seconds after the Ignition SW is turned OFF, the functioning of this relay makes it possible to open and close the Moon Roof. Also, by opening the front Door (Door Courtesy SW ON) within about 60 Seconds after turning the Ignition SW to OFF, a signal is input to TERMINAL B-3 of Theft Deterrent ECU. As a result, the ECU turns OFF and open and close movement of the Moon Roof stops.
