System Outline

When the ignition SW is turned on, current flows through the GAUGE fuse to TERMINAL 1 of the P/W relay and out TERMINAL 2 to GROUND. This activates the relay and the current flows through the POWER fuse to TERMINAL 5 of the relay, out TERMINAL 3 to TERMINAL B of the power window master SW and TERMINAL 4 of the power window control SW front RH and TERMINAL 3 of the power window control SW rear LH, RH.

  1. Manual Operation (Driver's Window) 

    If the ignition SW is in the ON position and the power window master SW (Front LH) is lifted and held up, the current flowing to TERMINAL B of the power window master SW flows to TERMINAL DU of the master SW to TERMINAL 4 of the power window motor and out TERMINAL 5 to TERMINAL DD of the master SW then out TERMINAL E to GROUND, and rotates the power window motor in the up direction. The window ascends only as long as the SW is being held up. When the switch is pushed slightly down, current flows in TERMINAL B of the power window master SW, out TERMINAL DD to TERMINAL 5 of the motor then out TERMINAL 4 to TERMINAL DU of the master SW and finally out TERMINAL E to GROUND, flowing in the opposite direction to the manual up operation and rotating the motor in reverse, thus opening the window.

  2. Auto Down Operation (Driver's Window) 

    When the front LH window control SW on the power window master SW is pushed fully down, current flows from TERMINAL B of the master SW then out TERMINAL DD to TERMINAL 5 of the power window motor and out TERMINAL 4 to TERMINAL DU of the master SW then finally out TERMINAL E 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 power window master SW is released. When the driver's window is fully opened, the hold circuit turns off and the relay on the down side turns off, and the auto down operation is considered to be completed.

  3. Stopping of Auto Down Operation (Driver's Window) 

    If the master SW (Front LH) is pulled up during auto down operation, a ground circuit opens in the master SW and current does stops flowing from TERMINAL DU of the master SW and out TERMINAL E, so the motor stops, causing the auto down operation to stop. If the master SW is pulled up and held, then the motor rotates in the up direction in a manual up operation.

  4. Manual Operation (Front RH Window) 

    When the power window control SW (Front RH) is pulled up and held, current flowing into TERMINAL 4 of the power window control SW flows out TERMINAL 3 to TERMINAL 4 of the power window motor then out TERMINAL 5 to TERMINAL 1 of the power window control SW and out TERMINAL 2 to TERMINAL PD of the master SW and finally out TERMINAL E to GROUND and rotates the power window motor (Front RH) in the up direction. The up operation continues only as long as the power window control SW is held up. When the window descends, the current flowing to the motor flows in the opposite direction, 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 opens. As a result, even if the passenger window open or close operations are attempted, the current from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so the passenger window can not be operated and the window is locked.

  5. Manual Operation (Rear LH, Rear RH Window) 

    When the power window control SW (Rear LH, rear RH) is pulled up and held, current flowing into TERMINAL 4 of the power window control SW flows out TERMINAL 3 to TERMINAL 5 of the power window motor then out TERMINAL 4 to TERMINAL 1 of the power window control SW and out TERMINAL 2 to TERMINAL RLD and RRD of the master SW and finally out TERMINAL E to GROUND and rotates the power window motor (Rear LH, rear RH) in the up direction. The up operation continues only as long as the power window control SW is held up. When the window descends, the current flowing to the motor flows in the opposite direction, 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 opens. As a result, even if the passenger window open or close operations are attempted, the current from TERMINAL E of the power window master SW is not grounded and the motor does not rotate, so the passenger window can not be operated and the window is locked.
