POWER WINDOW SYSTEM
System Description
POWER WINDOW OPERATION
- Power window main switch can open/close all windows.
- Power window sub-switch can open/close the passenger side windows.
- Retained power operation can operate power window switch and power window sub-switch for 45 seconds after ignition switch is turned OFF.
- Power window lock function prohibits operation other than power window main switch when lock switch is pressed.
- Anti-pinch function lowers door glass a specific amount during power window AUTO UP operation when resistance is detected because of a trapped foreign object.
- Power window serial link transmits and receives signal between retractable hard top control unit and power window main switch or power window sub-switch.
- Power window system operation links with retractable hard top system to System Description, "RETRACTABLE HARD
TOP SYSTEM : System Description".
POWER WINDOW AUTO-OPERATION
- Driver and passenger power window motors operate AUTO UP/DOWN when power window main switch or power window sub-switch is operated in AUTO.
- Power window main switch and power window sub-switch read the changes of encoder signal and stop
AUTO operation when door glass is fully open or closed.(Anti-pinch function does not operate just before door glass is fully closed and before it is fully closed.)
- Even if encoder is malfunctioning, power window motors are operative (except during AUTO operation).
- For rear power window motor, only AUTO DOWN operation is operative.
POWER WINDOW SIMULTANEOUS OPERATION
All door glass moves upward (downward) when driver side front switch and passenger side front switch of power window main switch are simultaneously pulled (pressed) in AUTO position.
NOTE:
This function is adopted in consideration of convenience after all door glass is fully closed (open) when retractable hard top is operated.
POWER WINDOW SERIAL LINK
Power window main switch, power window sub-switch and retractable hard top control unit transmit and receive the signal by power window serial link.
The under mentioned signal is transmitted from retractable hard top control unit to power window main switch.
- Retractable hard top operation signal (front power window down signal,front power window up operation prohibition signal)
- Keyless power window down signal
The under mentioned signal is transmitted from retractable hard top control unit to power window sub-switch.
- Retractable hard top operation signal (front power window down signal, front power window up operation prohibition signal)
- Keyless power window down signal
The under mentioned signal is transmitted from power window main switch to power window sub-switch.
- Passenger side door window operation signal
- Power window control by key cylinder switch signal
- Retained power operation signal
- Power window lock signal
The under mentioned signal is transmitted from power window main switch to retractable hard top control.
- Rear power window operation signal
- Power window control by key cylinder switch signal
- Power window lock signal
RETAINED POWER OPERATION
- During 45 seconds after ignition switch is turned OFF, BCM controls timer and enables open and close operation of driver door glass, passenger door glass, and rear quarter glass.
NOTE:
Retained power operation is not operative when system initialization is not complete.
Retained power function cancel conditions
When BCM detects the following signal it cancels.
- Door CLOSE (door switch OFF) to OPEN (door switch ON).
- Ignition switch is ON.
- Timer time passes. (45 seconds)
POWER WINDOW LOCK FUNCTION
Window lock signal is sent to retractable hard top control and power window sub switch via serial link, and switch operation other than power window main switch is prohibited.
NOTE:
Power window operates when retractable hard top operated while power window lock switch is ON.
ANTI-PINCH FUNCTION
- Foreign material in the door glass during AUTO-UP operation the anti-pinch function that lowers the door glass 150 mm or 2 seconds when detected.
- Encoder continues detecting the movement of power window motor and transmits to power window switch as the encoder pulse signal while power window motor is operating.
- Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass.
- Power window switch controls to lower the window glass for 150 mm or 2 seconds after it detects encoder pulse signal frequency change.
OPERATION CONDITION
- When all 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.
KEY CYLINDER SWITCH OPERATION
Hold the door key cylinder the LOCK or UNLOCK direction for 1 second or more to OPEN or CLOSE all power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL when operating.
OPERATION CONDITION
- Ignition switch OFF.
- Hold door key cylinder LOCK position for 1 second or more to perform CLOSE operation of the door glass.
- Hold door key cylinder UNLOCK position for 1 second or more to perform OPEN operation of the door glass.
KEYLESS POWER WINDOW DOWN OPERATION
All power windows open when the unlock button on Intelligent Key is activated and kept 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 ignition switch is turned ON while the power window opening is operated.
- When the unlock button is released.
While retained power operation keyless power window down function cannot be operated.
Keyless power window down operation mode can be changed by "PW DOWN SET" mode in "WORK SUPPORT". CONSULT-III Function (BCM - Intelligent Key).
NOTE:
Use CONSULT-III to change settings.
MODE 1 (3 sec) / MODE 2 (OFF) / MODE 3 (5 sec)
AUTOMATIC WINDOW ADJUSTING FUNCTION
- When the driver's/passenger's door(s) is opened, the window of the opened door is lowered approx. 10 mm
(0.39 in).Door is closed, door glass returns to the fully closed and closing operability and door glass airtightness are improved by this function.
- This function is operative while power window is locked.
- Opening and closing state of door is judged according to door switch ON or OFF position.
- Automatic window adjusting function is operative regardless of retractable hard top system state.
Non-operation condition
- Before automatic window adjusting function starts to lower door glass, door glass is 10 mm (0.39 in) or more open from the fully closed position.
- Door is closed while automatic window adjusting function is lowering door glass.
