Component Function
BCM • Supplies power to power window switches.
• Controls retained power.
Front power window motor LH • Integrates the ENCODER POWER and WINDOW MOTOR.
• Starts operating with signals from main power window and door lock/unlock switch.
• Transmits power window motor rotation as a pulse signal to main power window and door lock/unlock switch.
Front power window motor RH Starts operating with signals from main power window and door lock/unlock switch &
power window and door lock/unlock switch RH.
Main power window and door lock/un-
lock switch • Directly controls all power window motor of all doors.
• Controls anti-pinch operation of front power window LH.
Power window and door lock/unlock
switch RH • Controls front power window motor RH.
Rear power window switch • Controls rear power window motors LH and RH.
Rear power window motor Starts operating with signals from main power window and door lock/unlock switch &
rear power window switch.
Front door switch LH or RH Detects door open/close condition and transmits to BCM.

POWER WINDOW OPERATION
• Power window system is activated by the power window
switch when the ignition switch is in the ON position
or during the retained power operation after ignition switch is turned OFF.
• Main power window and door lock/unlock switch can open/close all windows.
• Front & rear power window switches can open/close the corresponding windows.
• Power window lock switch can lock all power windows other than driver seat.
• If door glass receives resistance that is more than t he specified value and the power window is in the AUTO-
UP operation (Front LH), power window will move in the reverse direction (Anti-Pinch Function).

• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch turns to AUTO.
• Encoder continues detecting the movement of power window motor and transmits to main power window
and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Main power window and door lock/unlock switch reads the changes of encoder signal and stops AUTO oper-
ation when door glass is at fully opened/closed position.
• Power window motor is operable in case encoder is malfunctioning.
RETAINED POWER OPERATION
• Retained power operation is an additional power supply function that enables power window system to oper-
ate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions
• Front door CLOSE (door switch OFF) →OPEN (door switch ON).
• When ignition switch is ON.
• When timer time passes. (45 seconds)
• AUTO function does not operate if encoder is malfunctioning.
POWER WINDOW LOCK FUNCTION
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock
switch is ON. This inhibits power window switch operation except with the main power window and door lock/
unlock switch.
ANTI-PINCH OPERATION (FRONT LH)
• Pinch foreign material in the door glass during AUTO-U P operation, and it is the anti-pinch function that low-
ers the door glass 150mm. (5.9 in .) or 2 seconds when detected.
• Encoder continues detecting the movement of power window motor and transmits to main power window and door lock/unlock switch as the encoder pulse signal while power window motor is operating.
• Resistance is applied to the power window motor ro tation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
• Power window switch controls to lower the window gla ss for 150 mm. (5.9 in.) or 2 seconds after it detects
encoder pulse signal frequency change.
OPERATION CONDITION
• When door glass 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.
KEYLESS POWER WINDOW DOWN FUNCTION
All power windows open when the unlock button on Intelligent Key is activated and pressed for more than 3
seconds with the ignition switch OFF. The windows keep opening if the unlock button is continuously pressed.
The power window opening stops when the following operations are performed:
• When the unlock button is pressed for more than 15 seconds.
• When the ignition switch is turned ON while the power window opening is operated.
• When the unlock button is released.
While retained power operation activate, keyless power window down function cannot be operated.
Fail-safeINFOID:0000000009460823
FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is det ected in the encoder signal that detects UP/DOWN speed
and direction of door glass. Switches to fail-safe control when an error beyond the regulation value is detected
between the fully closed position and the actual position of the glass.
Malfunction Malfunction condition
Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
Both pulse sensors mal-
function When both pulse signals have not been detected for more than the specified value during glass
open/close operation.
Pulse direction malfunc-
tion When the pulse signal that is detected during glass open/close operation detects the opposite con-
dition of power window motor operating direction.

DIAGNOSIS SYSTEM (BCM)
COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009955247
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
CAN Diag Support Mntr The result of transmit/receive diagnosis of CAN communication is displayed.
