- SLIDING ROOF SYSTEM DESCRIPTION
- The sliding roof system controls the sliding roof operation using the sliding roof ECU (sliding roof drive gear assembly). Operating the sliding roof switch (roof console box sub-assembly) results in electrical power being transmitted to the sliding roof ECU (sliding roof drive gear assembly).
- FUNCTION OF MAIN COMPONENT
The sliding roof system consists of the following components:
Component Outline Sliding roof ECU (Sliding roof drive gear assembly) Controls the rotational direction of the motor, which tilts or slides the sliding roof. Sliding roof switch (Roof console box sub-assembly) Outputs operation signals to the sliding roof ECU (sliding roof drive gear assembly). - SYSTEM FUNCTION
The sliding roof system has the following functions:
Function Outline Manual slide open and close function This function causes the sliding roof to open (or close) when the OPEN switch (or CLOSE switch) is pressed for a maximum of 0.3 seconds. The sliding roof stops as soon as the switch is released. Auto slide open and close function This function causes the sliding roof to reach the comfort stop position or fully open (or fully close) when the OPEN switch (or CLOSE switch) is pressed for a minimum of 0.3 seconds. Manual tilt up and down function This function causes the sliding roof to tilt up (or tilt down) when the UP switch (or DOWN switch) is pressed for a maximum of 0.3 seconds. The sliding roof stops as soon as switch is released. Auto tilt up and down function This function causes the sliding roof to fully tilt up (or tilt down) when the UP switch (or DOWN switch) is pressed for a minimum of 0.3 seconds. Jam protection function The jam protection function automatically stops the sliding roof and moves it open halfway (or fully tilt up) if foreign matter gets jammed in the sliding roof during close or tilt down operation. Key-off operation function The key-off operation function makes it possible to operate the sliding roof for approximately 45 seconds after the power switch is turned from on (IG) to off, if both the driver door and front passenger door are not opened. Key-linked function* - When the electrical key transmitter sub-assembly is not in the vehicle, the driver door is unlocked, and the driver door key cylinder is turned and held in the unlock position for 2.5 seconds or more, the sliding roof ECU (sliding roof drive gear assembly) activates the sliding roof motor to open the sliding roof while the key cylinder is turned.
- When the electrical key transmitter sub-assembly is not in the vehicle, the driver door is locked, and the driver door key cylinder is turned and held in the lock position for 2.5 seconds or more, the sliding roof ECU (sliding roof drive gear assembly) activates the sliding roof motor to close the sliding roof while the key cylinder is turned.
Wireless transmitter-linked function* When the main body ECU (multiplex network body ECU) receives an unlock signal from the electrical key transmitter sub-assembly continuously for longer than 4 seconds, the sliding roof ECU (sliding roof drive gear assembly) activates the sliding roof motor to open the sliding roof while the switch of the electrical key transmitter sub-assembly is being pressed.
HINT:
This function is linked with the power window wireless transmitter-linked function.Sliding roof open warning function When the power switch is turned from on (IG) and the driver door is opened with the sliding roof open, the buzzer in the combination meter assembly sounds once and a warning message is displayed on the multi-information display. - *: This function is set through the customize setting, as it is off by default.
