Sunroof / Moonroof: Description and Operation

SLIDING ROOF: SLIDING ROOF SYSTEM: SYSTEM DIAGRAM

1. SYSTEM DIAGRAM





2. SYSTEM OUTLINE

In the system, the sliding roof control ECU detects changes in the motor rotation to allow opening/closing and tilting up/down of the sliding roof using one touch operation. Additionally, jam protection mechanism is provided.

Voltage is always applied from the S/ROOF fuse to TERMINAL 5 of the sliding roof control ECU. When the ignition switch is turned on (IG), voltage is applied from the ECU-IG No.1 fuse to TERMINAL 8 of the sliding roof control ECU.

(a) SLIDING OPEN OPERATION

(1) When the sliding roof control switch is pressed to the OPEN position, a signal is input from TERMINAL 6 of the sliding roof control switch to TERMINAL 9 of the sliding roof control ECU. This activates the sliding roof control ECU, which rotates the motor to open the sliding roof. The sliding roof control ECU determines that the sliding roof is opened (30 mm (1.18 in.) from the fully opened position), and stops the motor rotation. When the sliding roof control switch is pressed to the OPEN position again, it fully opens the sliding roof.

If order operation or open switches are operated while the sliding roof is being opened, the sliding roof control ECU activates to stop the sliding roof operation. While the sliding roof is tilted up, the slide open operation does not function.

(b) SLIDE CLOSE OPERATION

(1) When the sliding roof control switch is pressed to the CLOSE position, a signal is input from TERMINAL 5 of the sliding roof control switch to TERMINAL 10 of the sliding roof control ECU. This activates the sliding roof control ECU and rotates the motor which automatically closes the sliding roof. The sliding roof control ECU determines that the sliding roof is fully closed, and stops the motor rotation.

If other operation or close switches are operated while the sliding roof is being closed, the sliding roof control ECU activates to stop the sliding roof operation.

(c) TILT UP OPERATION

(1) When the sliding roof control switch is pressed to the TILT UP position, a signal is input from TERMINAL 5 of the sliding roof control switch to TERMINAL 10 of the sliding roof control ECU. This activates the sliding roof control ECU and rotates the motor, which automatically tilts up the sliding roof. The sliding roof control ECU determines that the sliding roof is fully tilted up and the motor has stopped, and stops the current flowing into the motor.

If other operation or tilt up switches are operated while the sliding roof is being tilted up, the sliding roof control ECU activates to stop the sliding roof operation. While the sliding roof is open, the tilt up operation does not function.

(d) TILT DOWN OPERATION

(1) When the sliding roof control switch is pressed to the TILT DOWN position, the signal is input from TERMINAL 6 of the sliding roof control switch to TERMINAL 9 of the sliding roof control ECU. This activates the sliding roof control ECU and rotates the motor, which automatically tilts down the sliding roof. The sliding roof control ECU determines that the sliding roof is fully closed and the motor has stopped, and stops the current flowing into the motor.

If other operation or tilt down switches are operated while the sliding roof is being tilted down, the sliding roof control ECU activates to stop the sliding roof operation.

(e) JAM PROTECTION FUNCTION

(1) If the sliding roof control ECU detects a caught object from changes in the motor rotation during slide close or tilt down operation, the operation is stopped and then the motor is rotated in the reverse direction.

Slide close operation:

The sliding roof is moved approximately 200 mm (7.78 in.) in the reverse direction (slide open) after a caught object has been detected. However, if the full open position is detected before moving approximately 200 mm (7.78 in.), the reverse movement is stopped.

Tilt down operation:

If a caught object is detected during tilt down operation, the sliding roof is fully tilted up.

(f) KEY OFF SLIDING ROOF OPERATION

(1) The sliding roof can also be operated for approximately 43 seconds after the ignition switch is turned from on (IG) to off with all doors closed. However, if the driver side door is opened during the operation, the operation is canceled.

(g) FAIL SAFE FUNCTION

(1) If the sliding roof is operated continuously in the same operating direction, the current flowing into the motor is cut off when the time shown below has elapsed after the motor operation is started.

Slide open/close operation with the sliding roof control switch: Approximately 20 seconds.

Tilt up/down operation with the sliding roof control switch: Approximately 3.5 seconds.

Slide open operation for reverse movement when activating the jam protection function: Approximately 20 seconds.

Tilt open operation for reverse movement when activating the jam protection function: Approximately 3.5 seconds.
