System Description
POWER WINDOW OPERATION
- Power window system is activated by power window switch operation when ignition switch turns ON, or during the retained power operation after ignition switch turns OFF.
- Power window main switch can open/close door glass.
- Front and rear power window switch can open/close the corresponding door glass.
- Power window lock switch can lock all power windows other than driver seat.
- All power windows open when pressing Intelligent Key unlock button for 3 seconds.
- If door glass receives resistance that is the specified value or more while power window of each seat is in
AUTO-UP operation, power window operates in the reverse direction.
- Power window serial link transmits the signals from power window main switch to each power window switch.
- AUTO UP/DOWN operation can be performed when front power window switch turns to AUTO.
POWER WINDOW AUTO-OPERATION
- AUTO UP/DOWN operation can be performed when each power window motor turns to AUTO.
- 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.
- 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 SERIAL LINK
Power window main switch, front power window switch (passenger side), rear power window switch and BCM
transmit and receive the signal by power window serial link.
The signal mentioned below is transmitted from BCM to power window main switch, front power window switch (passenger side) and rear power window switch.
- Keyless power window down signal
- Door switch signal
The signal mentioned below is transmitted from power window main switch to front power window switch (passenger side) and rear power window switch.
- Front passenger side door window and rear door window operation signal
- Power window control by door key cylinder switch signal
- Power window lock switch signal
- Retained power operation signal
RETAINED POWER OPERATION
- Retained power operation is an additional power supply function that enables power window system to operate during the 45 seconds even when ignition switch is turned OFF.
- Front door CLOSE (door switch OFF)->OPEN (door switch ON).
- When ignition switch is ON again.
- When timer time passes. (45 seconds)
POWER WINDOW LOCK FUNCTION
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 OPERATION
- Anti-pinch foreign lowers door glass 150 mm (5.9 in) when foreign material is pinched in door glass during
AUTO-UP operation.
- 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 door glass for 150 mm (5.9 in) 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.
DOOR KEY CYLINDER SWITCH OPERATION
Hold the door key cylinder to the LOCK or UNLOCK direction for 1.5 seconds 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 to LOCK position for 1.5 seconds or more to perform CLOSE operation of the door glass.
- Hold door key cylinder to UNLOCK position for 1.5 seconds or more to perform OPEN operation of the door glass.
KEYLESS POWER WINDOW DOWN FUNCTION
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 unlock button is kept pressed 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.
Keyless power window down operation mode can be changed by "PW DOWN SET" mode in "WORK SUPPORT". Intelligent Key.
NOTE:
Use CONSULT to change settings.
MODE 1 (3 sec) / MODE 2 (OFF) / MODE 3 (5 sec)
