Sunroof / Moonroof: Description and Operation

Current is applied at all times through the power fuse to TERMINAL 5 of the power relay. With the ignition SW turned ON, the current flows through the GAUGE fuse --> TERMINAL 7 of the integration relay --> TERMINAL A-3 --> TERMINAL 1 of the power relay --> TERMINAL 2 --> GROUND.

As a result, power relay is activated and the current to TERMINAL 5 of the power relay flows from TERMINAL 1 of the power relay to --> TERMINAL 4 of the moon roof control SW and moon roof control relay.

1. SLIDE OPEN OPERATION
When turning the slide open SW 'ON' with the roof closed, the moon roof control SW and moon roof control relay will make the motor rotate to the 'open' direction until they become any of the following conditions such as the TERMINAL IG becomes 'OFF' or any of the SWs is turned 'ON' or the time limit (about 20 seconds) is up or the current goes up the upper limit (about 17 ampere).

2. SLIDE CLOSE OPERATION
When turning the slide close SW (tilt up) 'ON' with the roof open, the moon roof control SW and moon roof control relay will make the motor rotate to the 'close' direction until they become half position (LS1 SW turns from 'ON' to 'OFF'). under the condition with the roof half closed. When turning the slide close SW (tilt up) 'ON' again, they will make the motor rotate until the roof is completely closed.

3. TILT UP OPERATION
With the roof closed, when the tilt up switch is pushed ON, the moon roof control SW and moon roof control relay drives the motor in direction of up (LS1 SW OFF, LS2 SW OFF).

4. TILT DOWN OPERATION
When the roof up, when the tilt down switch (slide open) is pushed ON, the moon roof control SW and moon roof control relay drives the motor in direction of down, and the motor stops at fully down position (LS1 SW OFF to ON).

5. KEY OFF MOON ROOF OPERATION
With the ignition SW turned from ON to OFF, integration relay operates and current flows from the door fuse to TERMINAL A-1 of the relay --> TERMINAL A-3 --> TERMINAL 1 of the power relay --> TERMINAL 2 --> GROUND for about 43 seconds. The same as normal operation, the current flows from the power fuse to TERMINAL 5 of the power relay --> TERMINAL 3 --> TERMINAL 4 of the moon roof control SW and moon roof control relay. As a result, for about 43 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 43 seconds after turning the ignition SW to OFF, a signal is input to TERMINALS 6 or A-6 of the integration relay. As a result, the relay turns OFF and open close movement of the moon roof stops.
