Stop condition of the door windows: it is the same as that of power windows. In the 

stepping mode, once another switch is turned on, the operation (of lowering switch in 

raising operation/lowering switch/raising switch in raising operation) stops. 

 

2. Supplying circuit of power window (see theftproof computer)

 

3. Inspection of the circuit of the power window 

（

1）In this circuit, for the BCM computer (theftproof computer) controlled power 

window, the direction of the current through the power window motor is changed 

automatically to make the motor rotating clockwise or anticlockwise, so that the door 

window is raised or lowered. 

（

2）If the start-up switch turned on, the BCM computer (theftproof computer) actuates 

the power window by supplying operating signal to the power window switch. 

（

3）If the start-up switch turned off, the BCM computer (theftproof computer) actuate 

the power window relay within the operating delay of 30s, i.e. after the start-up switch 

turned off, all the door windows can be actuated within 30s. 

（

4）Push the power window switch upward or downward (over 0.3s), the BCM 

computer (theftproof computer) instructs with signal to supply forward or backward 

current, so as to rotate the power window motor clockwise or anticlockwise. 

（

5）With the start-up switch on, push the power window switch upward or downward, 

check if there is forward or backward current output on the terminals of the BCM 

computer (theftproof computer). If not, the switch is defective, if voltage is output 

thereon, but the power window wouldn’t rise or lower, then the power window motor is 

defective.

Inspection and Repair

 of Electric Components 

（

1）control device of the power window 

Check the conductance of the power window main switch as shown in the figure. If it 

does not conform to the figure, replace the power window main switch.

On the door interior panel of the drive side, an rear window secure switch button is 

provided. Push the button, the power windows switches of the by-driver side and the 

both rear door windows are deactivated. Then the corresponding window switches can 

only be controlled from the window switch on the driver side.   

Description of the switches 

Among all the four doors, the control switch for the other three doors, rearview mirror 

adjust switch and secure switch are only provided on the front left door. 

Note:  with the secure switch the switched on the rear doors can be locked. Only when 

the secure switch is pulled out, the rear windows can be opened and closed with these 

switches. 

（

3）Check the conductance of switches on the passenger door window, rear left door 

window and rear right window as shown in the figure. If it does not conform to the figure, 

replace the power window switch.

the figure; connect the terminals reversely, check if the motor rotates anticlockwise. If 

the result is not as mentioned, replace the front left power window motor.
