Windows: Description and Operation

1. MANUAL DOWN OR UP OPERATION (DRIVER'S, FRONT PASSENGER'S WINDOW)
The signal is input to TERMINAL DWN1 of the power window motor and ECU front LH or RH while the power window master SW or the power window control SW front RH is kept pressed one step. This activates the power window motor and ECU front LH or RH to flow the current from into the power window motor to the power window motor and ECU front LH or RH to GROUND, to rotate the motor and open the window.
The signal is input to TERMINAL UP1 of the power window motor and ECU front LH or RH while the power window master SW or the power window control SW front RH is kept pulled one step. This activates the power window motor and ECU front LH or RH to flow the current from into the power window motor to the power window motor and ECU front LH or RH to GROUND, to reversely rotate the motor and close the window. When the window lock SW is pushed to the lock side, the ground circuit to the front passenger's window becomes open. As a result, even if Open/Close operation of the front passenger's window is tried, power window master SW is not grounded and the motor does not rotate, so the front passenger's window can not be operated and window lock occurs.

2. AUTO DOWN OR UP OPERATION (DRIVER'S, FRONT PASSENGER'S WINDOW)
The signals are input to TERMINALS DWN1 and AUTO of the power window motor and ECU front LH or RH when the power window master SW or the power window control SW front RH is pressed two steps. According to these signals, it is determined that the power window motor and ECU front LH or RH is in the auto mode. The current flows from into the power window motor to the power window motor and ECU front LH or RH to GROUND, to rotate the motor and automatically open the window.

3. POWER WINDOW OPERATION LINKED WITH DOOR KEY LOCK AND UNLOCK SW
When the ignition key is inserted into the door key cylinder on the driver or passenger side and kept turned to the lock or unlock position for approximately 1.5 sec. or longer, driver's and front passenger's door windows can be opened or closed.

Power window close operation
When the ignition key is inserted into the door key cylinder and kept turned to the lock position for 1.5 sec. or longer, the signal from the door key lock and unlock SW is input to TERMINAL A 18 of the integration relay to TERMINAL A 21 to TERMINAL UP2 of the power window ECU front LH and RH. The current flows from into the power window motor to the power window motor and ECU front LH and RH to GROUND, to close driver's and front passenger's door windows.

Power window open operation
When the ignition key is inserted into the door key cylinder and kept turned to the unlock position for 1.5 sec. or longer, the signal from the door key lock and unlock SW is input to TERMINAL A 19 or A 20 of the integration relay to TERMINAL A 23 to TERMINAL DWN2 of the power window motor and ECU front LH and RH. The current flows from power window motor and ECU front LH and RH into the power window motor to the power window motor and ECU front LH and RH to GROUND, to open driver's and front passenger 5 door windows.
If any of the following conditions is detected, the power window operation is stopped.

4. MANUAL OPERATION (REAR LH, RH WINDOW)
With the power window control SW rear LH or RH pulled to the up side, current flowing from TERMINAL 5 of the power window control SW flows to TERMINAL 2 of the power window control SW to TERMINAL 2 of the power window motor to TERMINAL 1 to TERMINAL 3 of the power window control SW to TERMINAL 1 to TERMINAL RLD or RRD of the master SW to TERMINAL 7 to GROUND and causes the power window motor rear LH or RH to rotate in the up direction. Up operation continues only while the power window control SW is pulled to the up side. When the window descends, the current flowing to the motor flows in the opposite direction, from TERMINAL 2 to TERMINAL 1, and the motor rotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit to the rear window becomes open. As a result, even if Open/Close operation of the rear window is tried, the current from TERMINAL 7 of the power window master SW is not grounded and the motor does not rotate, so the rear window can not be operated and window lock occurs.

5. CATCHING PREVENTION FUNCTION
If any foreign matter is caught in the window while it is rising, the pulse sensor installed in the power window motor detects changes in the number of motor rotations, forcibly lowers the door window 50 mm or if the door window opening amount is 200 mm or less, the window is lowered so that the opening amount is 200 mm.

6. KEY OFF POWER WINDOW OPERATION
With the ignition SW turned from ON to OFF, integration relay operates and current flows from DOOR fuse to TERMINAL A 1 of the relay to TERMINAL A 3 to TERMINAL 1 of power relay to TERMINAL 2 to GROUND, and TERMINAL A 3 of the relay to TERMINAL KOF of the power window motor and ECU front LH and RH for about 43 seconds. The same as normal operation, the current flows from POWER fuse to TERMINAL 5 of the power relay to TERMINAL 3 to TERMINAL 12 of the power window master SW and TERMINAL 3 of the power relay to TERMINAL 5 of the power window control SW rear LH, RH. As a result, for about 43 seconds after the ignition SW is turned OFF, the functioning of this relay makes it possible to raise and lower the power window. Also, by opening the front door (Door open detection SW ON) within about 43 seconds after turning the ignition SW to OFF, a signal is input to TERMINALS A 6 or 6 of the integration relay. As a result, the relay turns OFF and up and down movement of the power window stops.
