Windshield/window Glass: Overview Toyota Avalon XX30 рестайлинг

SYSTEM DESCRIPTION

1. POWER WINDOW CONTROL SYSTEM DESCRIPTION The power window control system controls the power windows' UP/DOWN function using regulator motors. The main controls of this system are: the multiplex network master switch assembly, which is built into the driver side door, and the power window regulator switches, which are built into the passenger side door and rear doors. Pressing each regulator switch on the multiplex network master switch assembly transmits a remote UP/DOWN signal to each power window regulator switch.
2. FUNCTION OF MAIN COMPONENT FUNCTION OF MAIN COMPONENT Component Outline Multiplex Network Master Switch Assembly Control window operations for all windows. Also, when window lock switch is set to lock position, window operation will only be possible for driver side power window. Multiplex Network Switch Assembly Located on passenger side door. Regulator switch assembly controls window operations for its respective window. Power Window Regulator Switch (Rear LH, RH) Located on rear door. Regulator switch assembly controls window operations for its respective window. Power Window Regulator Motor Assembly Receives switch signals and changes signals into motor activation. As a result, window position changes. Also, regulator motor assembly uses pulse sensor(s) to detect window position.
3. SYSTEM FUNCTION The power window control system has the following functions: POWER WINDOW CONTROL SYSTEM FUNCTION Function Outline Manual UP/DOWN function Function that raises window while power window switch is pulled halfway up and lowers window while switch is pushed halfway down. Window stops as soon as the switch is released. Auto UP/DOWN function Function that enables window to be fully opened or fully closed by one full push or pull of power window switch. Jam protection function Function that automatically stops power window and moves it downward if object is jammed in all power windows during AUTO UP operation. During key-off operation function, jam protection function works for manual UP and AUTO UP operation. Jam protection is available for front doors. Remote control function Function that allows multiplex network master switch assembly to control manual and AUTO UP/DOWN operations of passenger door power window and rear door power window. Key-off operation function Function that makes it possible to operate power window for approximately 43 seconds after ignition switch is turned to ACC or LOCK position and both front doors are closed. Window lock function Function where passenger door power window and rear door power windows' operations are disabled when window lock switch of the multiplex network master switch assembly is pressed. Passenger door power window and rear door power window can be operated when window lock switch is pressed again. Diagnosis Function where power window switch can detect malfunctions in power window system and make diagnoses. Power window switch light starts blinking to inform driver. Fail-safe Function that disables power window AUTO UP/DOWN function if pulse sensor (Hall IC) or limit sensor in power window regulator motor malfunction. Manual operation is possible through power window switches.

1. The defogger system and rear view mirror system use heater wires to defog the rear windshield and rear view mirror, respectively. The defogger switch is installed on the vehicles equipped with the rear window defogger system and rear view mirror system. The defogger switch operates both the defogger system and the rear view heater system. Both systems are part of the same circuit.
2. This system is activated when the ignition switch is turned on (IG) and the rear window defogger switch is pushed. This switch is provided with a timer function to keep the defogger and mirror heater on for approximately. 15 minutes.
