SYSTEM DESCRIPTION

  1. POWER WINDOW CONTROL SYSTEM DESCRIPTION The power window control system controls the power window UP/DOWN function by using regulator motors. This system is mainly controlled by the multiplex network master switch built into the driver's door and multiplex network switches built into the passenger's doors. Pressing any of these multiplex network switches or the driver side door window switch mounted on the master switch transmits an UP/DOWN signal to the regulator motor for the corresponding power window, which then operates the power window UP/DOWN. Pressing any switch for the power windows except the driver's power window mounted on the master switch transmits a remote UP/DOWN signal to the main body ECU RH via the BEAN line. Then the main body ECU RH transmits this remote signal to the regulator switch for the corresponding power window via the BEAN line and activates the motor to open/close the power window. The power window control system has the following functions: FUNCTION OUTLINE TABLE Function Outline Manual up-and-down function Function that causes window to go up while power window switch is being pulled halfway up and to go down while pushed halfway down. Window stops as soon as the switch is released. All door auto up-and-down function Function that enables window of all doors to be fully opened or closed by one press of power window switch. Jam protection function Function that automatically stops power window and moves it downward if a foreign object gets jammed in door window during auto-up operation. Remote control function Function that allows power window master switch to control AUTO and MANUAL up-and-down operations of front passenger door window and rear door windows. Key-off operation function Function that makes it possible to operate power window for approx. 45 seconds after engine switch is turned on (ACC) or off, if either front door is not opened. Key-linked up-and-down function Function that causes window to go up while driver's door key is turned to lock side for more than 1.5 seconds and to go down while turned to unlock side for more than 1.5 seconds. Window stops as soon as the key is returned to original position. Transmitter-linked down function Function that causes window to go down while unlock switch on transmitter is pressed for more than 2.5 seconds. Window stops as soon as the switch is released. Diagnosis Function that allows the power window switch to make a diagnosis for failed section when power window switch detects a malfunction in power window system. Power window switch light comes on or blinks to inform driver. Fail-safe A fail-safe function to disable a part of power window functions if pulse sensor in power window motor has a malfunction: All door auto up-and-down function and remote control function are disabled. Manual operation is possible by each power window switch.

  1. GENERAL The defogger system's thin heater wires are attached to the inside of the rear window and defog the window surface quickly. The indicator light illuminates while the system is operating. The system automatically turns off after approximately 15 minutes. HINT: The rear window defogger is linked with the mirror defogger.
  2. FUNCTION OF MAIN COMPONENT FUNCTION OF MAIN COMPONENT Component Outline DEFOG Relay Receives rear defogger activation request signals from A/C amplifier assembly (A/C ECU) and supplies power to rear window defogger. Rear Window Defogger Receives power from DEFOG relay and heats defogger wire.
  3. DESCRIPTION FUNCTION OUTLINE Function Outline Defogs the rear window surface Receives rear defogger activation request signals from A/C amplifier assembly (A/C ECU) and supplies power to rear window defogger. Receives power from DEFOG relay and heats defogger wire.

with Navigation System

When the rear window defogger switch, which is built into the multimedia module display assembly, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the DEFOG relay to operate the rear window defogger.

without Navigation System

When the rear window defogger switch, which is built into the integration control & panel, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the DEFOG relay to operate the rear window defogger.
