Sunroof / Moonroof: Description and Operation

SYSTEM OUTLINE

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 to TERMINAL 7 of the integration relay to TERMINAL (B) 23 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND, as a result, power relay is activated and the current to TERMINAL 5 of the power relay flows from TERMINAL 3 of the power relay to TERMINAL 3 of the moon roof ECU and motor.

1. SLIDE OPEN OPERATION
Only when the slide open switch is valid and actuated the moon roof motor continually will operate towards the open direction of the roof panel.
Releasing and again depressing the open switch, or depressing another operation switch shall cancel this express open function. The relay shall only operate the moon roof motor continually for approx. 20 seconds per actuation.

2. SLIDE CLOSE OPERATION
Only when the tilt up switch is valid and actuated the moon roof motor will operate towards the close direction of the roof panel.
When the moon roof reaches about 120 mm short of the fully closed position, the limit switch No.2 is turned from on to off. Thereby signaling the moon roof ECU to stop the motor. The motor can not continue to operate until the close switch is released and again depressed.

3. TILT UP OPERATION
Only when the tilt up switch is valid and actuated the moon roof motor will operate towards the closed direction of the roof panel.

4. TILT DOWN OPERATION
Only when the slide open switch is valid and actuated the moon roof motor will operate towards the open direction of the roof panel.

5. KEY OFF MOON ROOF OPERATION
With the ignition SW turned from on to off, the integration relay operates and current flows from the DOOR fuse to TERMINAL (B) 25 of the relay to TERMINAL (B) 23 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND for about 43 seconds. In the same way as normal operation, the current flows from the POWER fuse to TERMINAL 5 of the power relay to TERMINAL 3 to TERMINAL 3 of the moon roof ECU and motor. 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 open detection SW on) within about 43 seconds after turning the ignition SW to off, a signal is input to TERMINALS B or (B) 20 of the integration relay. As a result, the relay turns off and open close movement of the moon roof stops.
