System Outline

Current is applied at all times through the PWR fuse to TERMINAL 5 of the power main relay and also to TERMINAL 12 of the moon roof control relay. With the ignition SW turned ON, the current flows to TERMINAL (B) 7 of the theft deterrent and door lock ECU to TERMINAL (B) 6 to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND through the ECU-IG fuse.

As a result, power main relay is activated and the current to TERMINAL 5 of the power main relay flows from TERMINAL 3 of the power main relay to TERMINAL 6 of the 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 5 of the moon roof control SW to TERMINAL 1 of the moon roof control relay. 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 6 of the moon roof control relay flows from TERMINAL 5 to TERMINAL 3 of the moon roof motor to TERMINAL 1 to TERMINAL 4 of the moon roof control relay to TERMINAL 11 to 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 2 of the moon roof control SW to TERMINAL 2 of the moon roof control relay.

When this occurs, the relay is activated and the current to TERMINAL 6 of the moon roof control relay flows from TERMINAL 4 to TERMINAL 1 of the moon roof motor to TERMINAL 3 to TERMINAL 5 of the moon roof control relay to 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 100 mm (3.9 in) before fully CLOSED position, signal is input from TERMINAL 2 of the limit SW No. 1 to TERMINAL 8 of the moon roof control relay. This signal activates the relay and stops continuity from TERMINAL 6 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 light SW No. 2 is OFF), a signal is input from TERMINAL 1 of the moon roof control SW to TERMINAL 3 of the moon roof control relay. As a result, the relay is activated and the current to TERMINAL 6 of the moon roof control relay flows from TERMINAL 4 of the relay to TERMINAL 1 of the moon roof motor to TERMINAL 3 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 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 SW are both OFF), a signal is input from TERMINAL 3 of the moon roof control SW to TERMINAL 7 of the moon roof control relay.

As a result, the relay is activated and the current to TERMINAL 6 of the moon roof control relay flows from TERMINAL 5 of the relay to TERMINAL 3 of the moon roof motor to TERMINAL 1 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 theft deterrent and door lock ECU operates and current flows from the DOOR fuse to TERMINAL (B) 9 of the ECU and also the DOME fuse to TERMINAL (A) 1 of the ECU to TERMINAL (B) 6 to TERMINAL 1 of the power main relay to TERMINAL 2 to GROUND for about 60 seconds. The same as normal operation. the current flows from PWR 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 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 door LH, RH (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 theft deterrent and door lock ECU. As a result, the ECU turns OFF and open and close movement of the moon roof stops.
