System Outline

Current is applied at all times through PWR fuse to TERMINAL 12 of moon roof control relay. With the ignition SW turned ON, the current flows TERMINAL SIG of body ECU --> TERMINAL PWS --> TERMINAL 6 of moon roof control relay through GAUGE fuse.

1. SLIDE OPEN OPERATION
When the ignition SW is ON and the moon roof control SW is pushed to the open side for 0.5 seconds or more, a signal is output from TERMINAL 4 of the moon roof control SW to TERMINAL 1 of the moon roof control relay. (moon roof limit SW no.2 is ON at this time)

This activates the moon roof control relay, so current flows from the PWR fuse --> TERMINAL 12 of moon roof control relay --> TERMINAL 5 --> TERMINAL 2 of moon roof motor --> TERMINAL 1 --> TERMINAL 4 --> TERMINAL 11 --> 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 SW.

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 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 1 of 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 in) before fully closed position, a 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 continuous 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 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 12 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 12 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
When the ignition SW is turned from ON to OFF, the body ECU causes current from SEC HORN fuse to flow to TERMINAL BECU of the body ECU -->TERMINAL PWS -->TERMINAL 6. This permits the moon roof to be operated for about 45 seconds as with normal operation of the moon roof control relay. If the driver's door is opened during this period, a signal is input to TERMINAL MPX of the body ECU, current flow to TERMINAL PWS stops and the moon roof stops.
