System Outline

Current is applied at all times through the POWER fuse to TERMINAL 5 of the power main relay and TERMINAL 12 of the moon roof control relay. With the ignition SW turned ON, current flows to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND through the GAUGE fuse.
As a result, power main relay is activated and current to TERMINAL 5 of the power main relay flows from TERMINAL 3 of the power main relay to TERMINAL 6 of the moon root control relay.

1. SLIDE OPEN OPERATION
When the ignition SW is turned on and the moon roof control SW is pushed to OPEN position, current flows from TERMINAL 1 of the moon roof control relay to TERMINAL 3 of the moon roof control SW to TERMINAL 8 to GROUND. the moon root limit SW No.1 or No.2 is on at this time.
When this occurs, the relay is activated and current to TERMINAL 12 of the moon roof control relay flows from TERMINAL 5 to TERMINAL 1 of the moon roof motor to TERMINAL 3 to TERMINAL 4 of the moon roof control relay to TERMINAL 11 to GROUND, rotating 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 and the moon roof limit SW No.1 and No.2 both on (The moon roof completely opening), when the moon roof control SW is pushed to CLOSE position, current flows from TERMINAL 2 of the moon root control relay to TERMINAL 4 of the moon roof control SW to TERMINAL 8 to GROUND.
When this occurs, the relay is activated and current to TERMINAL 12 of the moon roof control relay flows from TERMINAL 4 to TERMINAL 3 of the moon root motor to TERMINAL 1 to TERMINAL 5 of the moon roof control relay to TERMINAL 11 to GROUND, rotating 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 200 mm (7.874 in.) before fully at CLOSE position, signal is input from TERMINAL 1 of the limit SW No.1 to TERMINAL 8 of the moon root control relay. This signal activates the relay and stops continuous from TERMINAL 12 of the 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 the 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), current flows from TERMINAL 3 of the moon roof control relay to TERMINAL 5 of the moon roof control SW to TERMINAL 8 to GROUND. As a result, the relay is activated and current to TERMINAL 12 of the moon roof control relay flows from TERMINAL 4 of the relay to TERMINAL 3 of the moon roof motor to TERMINAL 1 to TERMINAL 5 of the moon roof control relay to TERMINAL 11 to GROUND and rotates the motor so that tilt up operation occurs as long as the moon root 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 tiled up (No.1 and No.2 moon roof limit SW are both OFF), current flows from TERMINAL 7 of the moon roof control relay to TERMINAL 6 of the moon roof control SW to TERMINAL 8 to GROUND.
As a result, the relay is activated and current to TERMINAL 12 of the moon roof control relay flows from TERMINAL 5 of the relay to TERMINAL 1 of the moon roof motor to TERMINAL 3 to TERMINAL 4 of the moon roof control relay to 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 door lock control relay operates and current flows from the DOOR fuse through TERMINAL 8 of the relay or from the GAUGE fuse through TERMINAL 1 of the door lock control relay to TERMINAL 15 to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND for about 60 seconds. The same as normal operation, current flows from the POWER fuse to TERMINAL 5 of the power main relay to TERMINAL 3 to TERMINAL 6 of the moon roof control relay. as a result, for about 60 seconds afier 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 tuning the ignition SW to OFF, a signal is input to TERMINALS 2 or 14 of the door lock control relay.
As a result, the ECU turns OFF and open and close movement of the moon roof stops.
