TOYOTA LAND CRUISER 1998 Factory Repair Manual

2004 LAND CRUISER (EWD548U)
254Power Window
1. Manual Down or Up Operation
When the power window master SW is pressed one step, the current flows from the power window master SW TERMINAL
DN to the power window motor front LH to the power window master SW TERMINAL UP to GROUND, and rotates the motor
to open the window.
When the power window master SW is pulled one step, the current flows from the power window master SW TERMINAL UP
to the power window motor front LH to the power window master SW TERMINAL DN to GROUND, and rotates the motor to
close the window.
For the other windows, as the power window master SW and the power window SW is operated, the relevant door window is
opened or closed.
2. Auto Down or Up Operation
When the power window master SW is pushed two steps, the power window master SW determines it is in auto mode and
the current flows from the power window master SW TERMINAL DN to the power window motor front LH to the power
window master SW TERMINAL UP to GROUND, and rotates the motor to open the window automatically.
When the power window master SW is pulled two steps, the power window master SW determines it is in auto mode and the
current flows from the power window master SW TERMINAL UP to the power window motor front LH to the power window
master SW TERMINAL DN to GROUND, and rotates the motor to close the window automatically.
Accordingly, when each window switch of the power window control SW is operated, the relevant door window is
automatically opened/closed.
3. Catching Prevention Function
When any foreign matter is caught in the window during power window up operation, the pulse sensor in the power window
motor detects the changes in the number of motor rotations and forcibly opens the door window 50 mm, or when the window
opening is less than 200 mm, it opens the window until the opening is 200 mm.
4. Key Off Power Window Operation
It is possible to operate the power window for approx. 43 seconds after the ignition SW is turned from on to off. However,
when the door is opened while the window is being operated, the power window operation is stopped even though 43
seconds have not elapsed.

In this system, the HALL IC in the moon roof control ECU detects the changes in motor rotation, and allows opening/closing,
tilting up/down of the moon roof by one touch operation.
In addition, catching prevention function during moon roof operation is also provided.
Voltage is constantly applied from the SUN ROOF fuse to the moon roof control ECU TERMINAL 5 of the moon roof control
ECU.
When the ignition SW is turned on, the current flows from the ECU-IG1 fuse to TERMINAL 8 of the moon roof control ECU.
1. Slide Open Operation
When the moon roof control SW is kept pressed to OPEN position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit
SW No.2 on), a signal is input from the moon roof control SW TERMINAL 5 to the moon roof control ECU TERMINAL 9. This
activates the moon roof control ECU and rotates the motor to open the moon roof automatically. However, in case of
pressing the moon roof control SW for 0.3 seconds or less, the moon roof can be operated manually. Then, when the limit
SW No.1 is turned on and then turned off again, the pulse signal sent from the HALL IC activates the moon roof control ECU,
and determines that the moon roof is fully open, and stops the motor. If other operation SW or the open SW is operated while
the moon roof is being opened, the moon roof control ECU is activated to stop the moon roof operation. In addition, when the
moon roof is tilted up, the slide open operation does not function.
2. Slide Close Operation
When the moon roof control SW is kept pressed to CLOSE position for approx. 0.3 seconds or longer (Limit SW No.1 off,
limit SW No.2 off), a signal is input from the moon roof control SW TERMINAL 4 to the moon roof control ECU TERMINAL
10. This activates the moon roof control ECU and rotates the motor to close the moon roof automatically. However, in case of
pressing the moon roof control SW for 0.3 seconds or less, the moon roof can be operated manually. Then, when the limit
SW No.2 is turned on, the pulse signal sent from the HALL IC activates the moon roof control ECU, and determines that the
moon roof is closed fully, and stops the motor. If other operation SW or the close SW is operated while the moon roof is
being closed, the moon roof control ECU is activated to stop the moon roof operation.
3. Tilt Up Operation
When the moon roof control SW is kept pressed to UP position for approx. 0.3 seconds or longer (Limit SW No.1 off, limit SW
No.2 on), a signal is input from the moon roof control SW TERMINAL 1 to the moon roof control ECU TERMINAL 4. This
activates the moon roof control ECU and rotates the motor to tilt up the moon roof automatically. If the pulse signal is not
input from the HALL IC for 0.5 seconds or longer, it determines that the moon roof is fully tilted up, and stops the motor. If
other operation SW or the tilt up SW is operated while the moon roof is being tilted up, the moon roof control ECU is
activated to stop the moon roof operation. In addition, when the moon roof is opened, the tilt up operation does not function.
4. Tilt Down Operation
When the moon roof control SW is kept pressed to DOWN position for approx. 0.3 seconds or longer (Limit SW No.1 on, limit
SW No.2 on), a signal is input from the moon roof control SW TERMINAL 2 to the moon roof control ECU TERMINAL 3. This
activates the moon roof control ECU and rotates the motor to tilt down the moon roof automatically.
Then, when the limit SW No.1 is turned off, the pulse signal sent from the HALL IC activated the moon roof control ECU, and
determines that the moon roof is closed fully, and stops the motor.
If other operation SW or the tilt down SW is operated while the moon roof is being tilted down, the moon roof control ECU is
activated to stop the moon roof operation.
5. Catching Prevention Function
During slide close or tilt down operation, if the moon roof control ECU detects a catching load from the changes in the
rotation of the motor, the operation is stopped, and the motor is rotated in the reverse direction.
*Slide close operation
The moon roof is moved approx. 200 mm in the reverse direction (Slide open) after a catching load has been detected.
However, if the full open position is detected before moving approx. 200 mm, the reverse movement is stopped.
*Tilt down operation
If a catching load is detected, the moon roof is moved in the reverse direction until fully tilted up.
6. Key Off Moon Roof Operation
Within approx. 43 seconds after the ignition SW is turned from on to off, the moon roof can be operated. However, if the
driver or front passenger door is opened during this period of time, the moon roof operation is stopped even though 43
seconds have not elapsed.
7. Fail-Safe Function
If the moon roof is operated continuously in the same direction, the current flowing to the motor is cut off when the time
shown below has elapsed after the motor operation has been started.
*Slide open/close operation by the moon roof SW approx. 20 seconds
*Tilt up/down operation by the moon roof SW approx. 2 second
*Slide open operation for reverse movement in case of catching prevention function approx. 20 seconds
*Tilt up operation for reverse movement in case of catching prevention function approx. 2 seconds
