Power Window
System Outline
When the ignition SW is turned on, the current flows through the GAUGE fuse to TERMINAL 1 of the P/W relay to
TERMINAL 2 to GROUND. This activates the relay and the current flows through the POWER fuse to TERMINAL 5 of the
relay to TERMINAL 3 to TERMINAL B of the power window master SW, TERMINAL 4 of the power window control SW.
1. Manual Operation (Driver’s Window)
With the ignition SW turned on and with the power window master SW (Front LH) in Up position, 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 to TERMINAL 5 to TERMINAL DD of the master SW to TERMINAL E to GROUND and rotates the power
window motor in the up direction. The window ascends only while the SW is being pulled. In down operation, the flows of
current from TERMINAL B of the power window master SW to TERMINAL DD to TERMINAL 5 of the motor to TERMINAL 4
to TERMINAL DU of the master SW to TERMINAL E to GROUND, flowing in the opposite direction to 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 in the power window master SW is pushed strongly on the down side, current flows
from TERMINAL B of the master SW to TERMINAL DD to TERMINAL 5 of the power window motor to TERMINAL 4 to
TERMINAL DU of the master SW to 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
auto down operation is completed.
3. Stopping of Auto Down Operation (Driver’s Window)
When the master SW (Front LH) 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 E, so the motor stops, causing auto
down operation to stop. If the master SW is pulled continuously, the motor rotates in the up direction in manual up operation.
4. Manual Operation (Front RH Window)
With the power window control SW (Front RH) pulled to the up side, current flowing from TERMINAL 4 of the power window
control SW flows to TERMINAL 3 to TERMINAL 4 of the power window motor to TERMINAL 5 to TERMINAL 1 of the power
window control SW to TERMINAL 2 to TERMINAL PD of the master SW to TERMINAL E to GROUND and rotates the power
window motor (Front RH) 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 4 to
TERMINAL 5, 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 attempted,
the current from TERMINAL E 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.
5. Manual Operation (Rear LH, Rear RH Window)
With the power window control SW (Rear LH, rear RH) pulled to the up side, current flowing from TERMINAL 4 of the power
window control SW flows to TERMINAL 3 to TERMINAL 5 of the power window motor to TERMINAL 4 to TERMINAL 1 of the
power window control SW to TERMINAL 2 to TERMINAL RLD, RRD of the master SW to TERMINAL E to GROUND and
rotates the power window motor (Rear LH, rear RH) 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 5 to TERMINAL 4, 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 attempted, the current from TERMINAL E 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.
