System Outline

Current is applied always through PWR Fuse to TERMINAL 5 of Power Main Relay and TERMINAL 12 of Moon Roof control relay. With the Ignition SW turned ON, current flows through TERMINAL 1 of Power Main Relay --> TERMINAL 2 --> GROUND through ECU-IG Fuse.

As a result, Power Main Relay is activated and the current flows to TERMINAL 5 of Power Main Relay flows from TERMINAL 3 of the Power Main relay to --> TERMINAL 6 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 OPEN position, a signal is input from TERMINAL 3 of Moon Roof control SW to TERMINAL 1 of Moon Roof control relay. The Moon Roof limit SW No.1 or No.2 is ON at this time.

When this occurs, the relay is activated and the current to TERMINAL 12 of Moon Roof control relay flows from TERMINAL 5 --> TERMINAL 1 of Moon Roof motor --> TERMINAL 3 --> TERMINAL 4 of the Moon Roof Control Relay --> TERMINAL 11 --> GROUND, and rotates the motor to open the Moon Roof while the SW is being pushed to OPEN position.

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 6 of Moon Roof control SW to TERMINAL 2 of Moon Roof control relay.

When this occurs, the relay is activated and the current to TERMINAL 12 of Moon Roof control relay flows from TERMINAL 4 --> TERMINAL 3 of Moon Roof motor --> TERMINAL 1 --> TERMINAL 5 of the Moon Roof Control relay --> TERMINAL 11 --> GROUND and rotates the motor to close the Moon Roof while the SW is being pushed to CLOSE position.

The Moon Roof limit SW No.1 turns OFF (limit SW No.2 is ON) and at 100 mm (3.9 in) before fully at CLOSED position, signal is input from TERMINAL 1 of limit SW No.1 into TERMINAL 8 of Moon Roof control relay. This signal activates the relay and stops continuity from TERMINAL 12 of Moon Roof control relay to TERMINAL 11. As a result, 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 5 of Moon Roof control SW into TERMINAL 3 of Moon Roof control relay. As a result, the relay is activated and the current to TERMINAL 12 of the Moon Roof Control relay flows from TERMINAL 4 of relay --> TERMINAL 3 of Moon Roof motor --> TERMINAL 1 --> TERMINAL 5 of Moon Roof Control relay --> TERMINAL 11 --> 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 2 of the Moon Roof control SW into TERMINAL 7 of the Moon Roof control relay.

As a result, the relay is activated and the current to TERMINAL 12 of the Moon Roof Control relay flows from TERMINAL 5 of the relay --> TERMINAL 1 of Moon Roof motor --> TERMINAL 3 --> TERMINAL 4 of Moon Roof Control relay --> TERMINAL 11 --> GROUND rotating the motors 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 OFF to ON.)

5. KEY OFF MOON ROOF OPERATION
(W/ theft deterrent)
With the ignition SW turned from ON to OFF, the theft deterrent and door lock control ECU operates and current flows from the DOOR fuse to TERMINAL B-9 of the ECU and the DOME fuse to TERMINAL A-1 of the ECU --> TERMINAL B-6 --> TERMINAL 1 of the power main relay --> TERMINAL 2 --> GROUND for about 60 seconds. The same as normal operation, the current flows from the PWR fuse --> TERMINAL 5 of the power main relay --> TERMINAL 3 --> 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 open detection SW ON) within about 60 seconds after turning the ignition SW to OFF, a signal is input to TERMINALS A-7 or A-19 of the theft deterrent and door lock control ECU. As a result, the ECU turns OFF and open and close movement of the moon roof stops.

(W/o theft deterrent)
With key ignition SW turned from ON to OFF, the door lock control relay operates and current flows from the door fuse to TERMINAL C-8 of the relay --> TERMINAL C-15 --> TERMINAL 1 of the power main relay --> TERMINAL 2 --> GROUND for about 60 seconds. The same as normal operation, the current flows from the PWR fuse --> TERMINAL 5 of the power main relay --> TERMINAL 3 --> 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 open detection SW ON)
Within about 60 seconds after turning the ignition SW to OFF, a signal is input to TERMINAL C-2 or C-14 of the door lock control relay. As a result, the relay turns OFF and open close movement of the moon roof stops.
