Windows: Description and Operation

When the ignition SW is turned ON, current flows through the ECU-IG fuse to TERMINAL 15 of the integration relay to TERMINAL 14 to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND. This activates the relay and the current flowing to TERMINAL 5 of the power relay from PWR fuse flows to TERMINAL 3 of the power relay to TERMINAL IG of the power window master SW, TERMINAL 4 (Front passenger's side), 3 (Rear LH, RH) of the power window SW.

1. MANUAL OPERATION (DRIVER'S WINDOW)
With the ignition SW turned ON and with the power window master SW in UP position, the current flowing to TERMINALS IG and +B of the master SW flows to TERMINAL DU of the master SW to TERMINAL 1 (4-door) or 4 (2-door) of the power window motor to TERMINAL 4 (4-door) or 1 (2-door) to TERMINAL DD of the master SW to TERMINAL GND (4-door) or E (2-door) to GROUND and causes the power window motor to rotate in the up direction. The window ascends only while the master SW is being pushed. In down operation, the current flowing from to TERMINALS IG and +B of the master SW to TERMINAL DD of the master SW causes the current flowing from TERMINAL 4 (4-door) or 1 (2-door) of the motor to flow to TERMINAL 1 (4-door) or 4 (2-door) to TERMINAL DU of the master SW to TERMINAL GND (4-door) or E (2-door) to GROUND, flowing in the opposite direction to manual up operation and causing the motor to rotate in reverse, lowering the window.

2. AUTO DOWN OPERATION (DRIVER'S WINDOW)
With the ignition SW ON and auto SW of the power window master SW in down side, current flows from TERMINALS IG and +B of the master SW to TERMINAL DD to TERMINAL 4 (4-door) or 1 (2-door) of the power window motor to TERMINAL 1 (4-door) or 4 (2-door) to TERMINAL DU of the master SW to TERMINAL GND (4-door) or E (2-door) to GROUND. Because the hold circuit inside the master SW keeps the relay on the down side activated, the power window motor continues operating even if the master SW is released. When the driver's window is fully lowered, the hold circuit turns OFF and the relay on the down side turns OFF, so auto down operation stops.

3. AUTO UP OPERATION (DRIVER'S WINDOW)
With the ignition SW ON and auto SW of the power window master SW in up side, current flowing to TERMINALS IG and +B of the master SW flows to TERMINAL DU to TERMINAL 1 (4-door) or 4 (2-door) of the power window motor to TERMINAL 4 (4-door) or 1 (2-door) to TERMINAL DD of the master SW to TERMINAL GND (4-door) or E (2-door) to GROUND, causing the power window motor to rotate towards the up side. Then the hold circuit in the master SW is activated and it locks the auto SW being pulled, causing the motor to continue to rotate in auto up operation.
When the window has completely ascended, the current flowing between TERMINAL DD of the master SW and TERMINAL GND (4-door) or E (2-door) increases. As a result, the hold circuit stops operating, the auto SW turns OFF and the flowing from TERMINALS IG and +B of the master SW to TERMINAL DU is cut OFF, stopping the motor so that auto stop occurs.

4. STOPPING OF AUTO DOWN OPERATION (DRIVER'S WINDOW)
When the power window master SW is pulled to the up side during auto down operation, a ground circuit opens in the master SW and current does not flow from TERMINAL DU of the master SW to TERMINAL GND (4-door) or E (2-door), so the motor stops, causing auto down operation to stop. If the master SW is pulled continuous, the motor rotates in the up direction in manual up operation.

5. STOPPING OF AUTO UP OPERATION (DRIVER'S WINDOW)
When the power window master SW is pushed to down side during auto up operation, a ground circuit opens in the master SW and current does not flow from TERMINAL DD of the master SW to TERMINAL GND (4-door) or E (2-door), so the motor stops, causing auto up operation to stop. If the master SW is pulled continuous, the motor rotates in the down direction in down operation.

6. MANUAL OPERATION (FRONT RH WINDOW)
With the power window SW (Front passenger's side) pulled to the up side, current flowing from TERMINAL 4 of the power window SW flows to TERMINAL 3 to TERMINAL 1 (4-door) or 2 (2-door) of the power window motor to TERMINAL 2 (4-door) or 1 (2-door) to TERMINAL 1 of the power window SW to TERMINAL 2 to TERMINAL PD of the master SW to TERMINAL GND (4-door) or E (2-door) to GROUND and causes the power window motor (Front passenger's side) to rotate in the up direction. Up operation continues only while the power window 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 (4-door) or 1 (2-door) to TERMINAL 1 (4-door) or 2 (2-door), and the motor rotates in reverse. When the window lock SW is pushed to the lock side, the ground circuit to the passenger's window becomes open. As a result, even if open/close operation of the passenger's window is tried, the current from TERMINAL GND (4-door) or E (2-door) of the power window master SW is not grounded and the motor does not rotate, so the passenger's window can not be operated and window lock occurs. Furthermore rear LH, RH window is operated operate the same as the above circuit.

7. CAUGHT PREVENTION OPERATION (DRIVER'S WINDOW)
At the time of one-touch automatic up operation, if foreign object is caught between a window frame and a glass, the glass rise will stop and reverse to descend.

8. KEY OFF POWER WINDOW OPERATION
With ignition SW turned from on to OFF, the integration relay operates and current flows from PWR fuse to TERMINAL 6 of the integration relay to TERMINAL 14 to TERMINAL 1 of power relay to TERMINAL 2 to GROUND for about 60 seconds. The same as normal operation, the current flows from PWR fuse to TERMINAL 5 of the power relay to TERMINAL 3 to TERMINAL IG of the power window master SW and through TERMINAL 3 of the power relay to TERMINAL 4 (Front passenger's side), 3 (Rear LH, RH) of the power window SW. As a result, for about 60 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 courtesy SW ON) within about 60 seconds after turning the ignition SW to OFF, a signal is input to integration relay. As a result, the relay turns OFF, and up and down movement of the power window stops.
