Outline

• An electric sunroof with tilt up mechanism has been adopted.
• A deflector has been added to reduce noise.
• A system control using pulse sensors (Hall effect switches) has been adopted for system simplification.
• A sunroof motor with an integrated CPU has been adopted.

Function


Tilt up/open/close

• When the sunroof switch (tilt position) is operated, the sunroof tilts up.
• When the sunroof switch (open position) is operated, the sunroof opens.
• When the sunroof switch (close position) is operated, the sunroof closes and tilts down.


Initial setting

• If the following operations have been performed, the initial setting is reset, and operation is disabled except for the tilt operation. Therefore, performing the initial setting is necessary.
― Negative battery terminal is disconnected
― Sunroof system power supply fuse is removed

Operation

• The glass panel opens/closes using tilting and sliding operations.
• When the ignition is switched ON (engine off or on), the sunroof operates by use of the sunroof switch.
• If the ignition is switched OFF or switched to ACC position while the sunroof is operating, it will stop.
• One-touch operation of the tilt or the slide open switch provides auto-operation.
• If any switch is operated during auto-operation, the sunroof stops.


Tilt up operation

1.When the sunroof switch is operated for tilt up operation, the CPU receives a tilt up signal (1).

2.When the CPU receives a tilt up signal, it turns on sunroof relay No.2 (2).

3.When sunroof relay No.2 is turned on, the sunroof motor starts tilt up operation (3).

4.When approx. 1 s. has elapsed after the sunroof motor was started, the timer control of the CPU turns off sunroof relay No.2 automatically to stop the tilt up operation.

Open operation

1.When the sunroof switch is operated for an open operation, the CPU receives an open signal (1).

2.When the CPU receives an open signal, it turns on sunroof relay No.1 (2).

3.When sunroof relay No.1 is turned on, the sunroof motor starts the open operation (3).

Close operation (glass panel open)

1.When the sunroof switch is operated for a close operation, the CPU receives a close signal (1).

2.When the CPU receives the close signal, it turns on sunroof relay No.2 (2).

3.When sunroof relay No.2 is turned on, the sunroof motor starts the close operation (3).

Close operation (glass panel tilt up)

1.When the sunroof switch is operated for a close operation, the CPU receives a close signal (1).

2.When the CPU receives the close signal, it turns on sunroof relay No.1 (2).

3.When sunroof relay No.1 is turned on, the sunroof motor starts the close operation (3).
