DRIVER SIDE
• Integrates the encoder and power window motor (driver side).
• Front power window motor (driver side) starts operation according
to signals from power window main switch.
• Transmits front power window motor (driver side) rotation as a
pulse signal to power window main switch.
PASSENGER SIDE
• Front power window motor (passenger side) starts operation
according to signals from power window main switch or front
power window switch (passenger side).
Rear Power Window Motor
INFOID:0000000010339807
• Starts operation according to signals from power window main
switch or each power window switches.

SYSTEM DIAGRAM
POWER WINDOW OPERATION
• BCM controls the power window relay, and controls the ignition ON power source supplied to each power
window switch.
• Power window system is activated by power window switch when ignition switch turns ON.
• Power window main switch opens/closes all door glass.
• Front and rear power window switch opens/closes the corresponding door glass.
• AUTO UP/DOWN operation can be performed when power window main switch turns to AUTO.
• Power window lock switch can lock all power windows other than driver seat.
• If door glass receives resistance that is the specified value or more while power window of driver seat is in
AUTO-UP operation, power window of driver seat operates in the reverse direction.
POWER WINDOW AUTO-OPERATION (FRONT DRIVER SIDE)
• AUTO UP/DOWN operation can be performed when power window main switch turns to AUTO.
• Encoder continues detecting the movement of power window motor and transmits to power window switch
as the encoder signal while power window motor is operating.
• Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at
fully opened/closed position.
• Power window motor is operable in case encoder is malfunctioning.
POWER WINDOW LOCK
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window main switch.
ANTI-PINCH SYSTEM (FRONT DRIVER SIDE)
• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low-
ers the door glass 120 – 150 mm (4.7 – 5.9 in) when detected.
• Encoder continues detecting the movement of front power window motor (driver side) and transmits to
power window main switch as the encoder signal while front power window motor (driver side) is operating.
• Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of
encoder signal if foreign material is trapped in the door glass.

• Power window main switch controls to lower the window glass for 120 – 150 mm (4.7 – 5.9 in) after it detects
encoder signal frequency change.
OPERATION CONDITION
• When front door glass (driver side) AUTO-UP operation is performed (anti-pinch function does not operate
just before the door glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower.
Fail Safe
INFOID:0000000010286481
FAIL-SAFE CONTROL
Power window main switch to fail-safe control when malfunction is detected in encoder signal that detects up/
down speed and direction of door glass. Power window main switch to fail-safe control when error beyond reg-
ulation value is detected between the fully closed position and the actual position of the glass.
It changes to condition before initialization and the following functions do not operate when power window
main switch to fail-safe control.
• Auto-up operation
• Anti-pinch function
Perform initial operation to recover when power window main switch to fail-safe mode. However, it power win-
dow main switch back to fail-safe control when malfunction is found in power window main switch or front
power window motor (driver side).
Error
Error condition
Pulse sensor malfunction
When only one side of pulse signal is detected for more than the specified time during glass open/
close operation
Both pulse sensors mal-
function
When both pulse signals are not detected for more than the specified time during glass open/close
operation.
Pulse direction malfunc-
tion
When the pulse signal detected during glass open/close operation continues in the condition that the
drive direction of power window motor is operating in the opposite direction for the specified time or
longer
Glass recognition position
malfunction
When it detects the error between glass fully closed position in power window main switch memory
and actual fully closed position during glass open/close operation is more than the specified value.
