POWER WINDOW OPERATION
- Power window system is activated by the power window switches when the push-button ignition switch is in the ON position or during the retained power operation after push-button ignition switch places OFF.
- Main power window and door lock/unlock switch can open/close door glass.
- Front and rear power window switches can open/close the corresponding door glass.
- Power window lock switch can lock all power windows other than driver front.
- Front power windows open when pressing Intelligent Key unlock button for 3 seconds.
- If door glass receives resistance that is more than the specified value and the power window is in the AUTO-UP operation, power window will move in the reverse direction (anti-pinch function).
REAR POWER SLIDE GLASS OPERATION (IF EQUIPPED)
- Rear power slide glass system is operable during the retained power operation timer after placing push-button ignition switch ON and OFF.
- Rear power slide glass switch can open/close the rear power slide glass.
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 outputs the encoder pulse signal to power window switch 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 open/closed position.
- Power window motor is operable in case encoder is malfunctioning.
- AUTO function does not operate if encoder is malfunctioning.
POWER WINDOW SERIAL LINK
Main power window and door lock/unlock switch, power window and door lock/unlock switch RH and BCM transmit and receive the signal by power window serial link. The signals mentioned below are transmitted from BCM to main power window and door lock/unlock switch and power window and door lock/unlock switch RH.
- Keyless power window down signal.
- Door switch signal. The signals mentioned below are transmitted from power window main switch to front power window switch (passenger side).
- Front passenger side door window operation signal.
- Retained power operation signal.
RETAINED POWER OPERATION
- Retained power operation is an additional power supply function that enables the power window system to operate for 45 seconds even after the push-button ignition switch is placed OFF.
Retained Power Function Cancel Conditions:
- Front door CLOSED (door switch OFF) →OPEN (door switch ON).
- When push-button ignition switch is ON again.
- When timer time passes (45 seconds).
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
- Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that lowers the door glass 150 mm (5.9 in) or 2 seconds when detected.
- Encoder continues detecting the movement of power window motor and transmits to the 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 lowers the door glass for 150 mm (5.9 in) or 2 seconds after it detects encoder pulse signal frequency change.
Operation Condition
When front door glass AUTO-UP operation is performed, anti-pinch function does not operate just before the door glass closes and is fully closed.
