Ito front power window switch RH terminal 11.
The subsequent operation is the same as the front power window switch RH operation.
FRONT POWER WINDOW SWITCH RH OPERATION
Power is supplied
Ithrough front power window switch RH (5, 4)
Ito front power window regulator RH (1, 3).
Ground is supplied
Ito front power window regulator RH (3, 1)
Ithrough front power window switch RH (4, 5)
Ito front power window switch RH terminal 12
Ithrough front power window main switch terminal 1.
Then, the motor raises or lowers the window until the switch is released.
Rear Door LHNBEL0102S0104Ground is supplied
Ito front power window main switch terminal 5
Ithrough body grounds the M77 and M111.
NOTE:
Numbers in parentheses are terminal numbers, when the power window switch is pressed in the UP and
DOWN positions.
FRONT POWER WINDOW MAIN SWITCH OPERATION
Power is supplied
Ithrough front power window main switch terminal (13, 12)
Ito rear power window switch LH terminal (3, 4)
The subsequent operation is the same as the rear power window switch LH operation.
REAR POWER WINDOW SWITCH LH
Power is supplied
Ithrough rear power window switch LH (1, 2)
Ito rear power window regulator LH (1, 2)
Ground is supplied
Ito rear power window regulator LH (2, 1)
Ithrough rear power window switch LH (2, 1)
Ito rear power window switch LH terminal (4, 3)
Ithrough front power window main switch terminal (12, 13)
Then, the motor raises or lowers the window until the switch is released.
Rear Door RHNBEL0102S0105Rear door RH windows will rise and lower in the same manner as the rear door LH window.
AUTO OPERATIONNBEL0102S02The power window AUTO feature enables the driver or front passenger to open or close the driver's and front
passenger's window without holding the window switch in the up or down position.
The AUTO feature only operates on the driver's and front passenger's window upward and downward move-
ment.
POWER WINDOW LOCKNBEL0102S03The power window lock is designed to lock operation of all windows except for driver's door window.
When the lock switch is pressed to lock position, the ground of the front and rear power window switches, in
the power window main switch, is disconnected. This prevents the power window motors from operating.
RETAINED POWER OPERATIONNBEL0102S04When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds
Ito power window relay terminal 2
Ifrom smart entrance control unit terminal 5.
Ground is always supplied

Ito power window relay terminal 1
Ithrough body grounds.
When power and ground are supplied, the power window relay continues to be energized, and the power win-
dow can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.
INTERRUPTION DETECTION FUNCTIONNBEL0102S05Front power window main switch and front power window switch RH monitor the power window regulator motor
operation and the power window position (full closed or other) for driver's and passenger's power window by
the signals from encoder and limit switch in front power window regulator LH or RH.
When front power window main switch or front power window switch RH detects interruption during the fol-
lowing close operation in the driver's or front passenger's side door,
Iautomatic close operation when ignition switch is in the ªONº position
Iautomatic close operation during retained power operation
front power window main switch or front power window switch RH controls driver's or front passenger's power
window regulator motor for open and the power window will be lowered about 150 mm (5.91 in).
