All Power Windows do not Operate with Driver Side Door Key Cylinder or Wireless Transmitter

DESCRIPTION

Wireless Transmitter-linked Function

When a key switch is pushed: 1) the door control receiver receives the wireless door lock signal; 2) the door control receiver sends a signal to the main body ECU (multiplex network body ECU) through the certification ECU (smart key ECU assembly); 3) the main body ECU (multiplex network body ECU) sends the operation permission signal to the power window regulator motor assemblies; and 4) the power window regulator motor assemblies are activated.

Key-linked Function

When the driver door key cylinder (key linked switch) is turned and held: 1) the door lock motor receives the signal; 2) the main body ECU (multiplex network body ECU) sends the signal to the power window regulator motor assemblies; and 3) the power window regulator motor assemblies are activated.

CAUTION / NOTICE / HINT

NOTICE:

These functions are set through customize settings, as they are off by default.
The power window control system uses the LIN communication system and CAN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting.

System Description

SYSTEM DESCRIPTION

POWER WINDOW CONTROL SYSTEM DESCRIPTION

(a) The power window control system controls the power window operation using the power window regulator motor assemblies. The main controls of this system are the multiplex network master switch assembly (mounted on the driver door), power window regulator switch assembly (mounted on the front passenger door) and rear power window regulator switch assemblies (mounted on the rear doors). Operating a window switch results in electrical power being transmitted to the corresponding power window regulator motor.

FUNCTION OF MAIN COMPONENTS

The power window control system consists of the following components:

Component	Outline
Multiplex Network Master Switch Assembly	Controls power window operation for all windows. Can be used to operate all of the power windows when the lock switch is on (pushed in)
Power Window Regulator Switch Assembly	Located on the front passenger door. Controls the front passenger power window operation.
Rear Power Window Regulator Switch Assembly LH Door RH Door	Located on the rear doors. Controls the power window operation of its respective window.
Power Window Regulator Motor Assembly	Receives switch signals and changes signals into motor activation. As a result, the power window position changes. Uses the Hall-ICs built into the regulator motor and the power window ECUs to detect the power window position and jamming.

SYSTEM FUNCTION

The power window control system has the following functions:

Function	Outline
Manual up and down function	Function that causes the power window to go up while the power window switch is being pulled halfway up and to go down while it is being pushed halfway down. The power window stops as soon as the switch is released.
Auto up and down function	Function that enables the power window of each door to be fully opened or closed by one full pull or push of the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly.
Window lock function	Function that disables the power window regulator switch assembly and rear power window regulator switch assembly operations when the window lock switch is on (pushed in). The power window regulator switch assembly and rear power window regulator switch assembly can be operated when the window lock switch is off (not pushed in).
Jam protection function	Function that automatically stops the power window and moves it downward if a foreign object gets jammed between the door and door glass during auto up or manual up operation.
Catch protection function	Function that automatically stops the power window if something gets caught between the door and door glass during auto down or manual down operation.
Remote control function	Function that allows the multiplex network master switch assembly to control manual and auto up and down operations of the front passenger door power window and rear door power windows.
Key-off operation function	Function that makes it possible to operate all power windows for approximately 45 seconds after the power switch is turned off when the driver door or front passenger door has not been opened. When 45 seconds have elapsed, or the driver door or front passenger door is opened after the power switch is turned off, the key-off operation function will be disabled. HINT: If a power window is being operated by auto operation while the key-off operation function is on, and the driver door or passenger door is opened, the power window will stop operating.
Key-linked function*	When the key is not inside the vehicle, the driver door is locked, and the driver door key cylinder is turned and held in the lock position for 1.5 seconds or more, the main body ECU (multiplex network body ECU) activates the power window regulator motor assemblies to close all of the power windows while the key cylinder is being turned. Similarly, when the driver door is unlocked, turning and holding the driver door key cylinder in the unlock position for 1.5 seconds or more will cause all of the power windows to open.
Wireless transmitter-linked function*	When the main body ECU (multiplex network body ECU) receives an UNLOCK signal from the key for 3 seconds or more, the main body ECU (multiplex network body ECU) sends an operation request signal to the power window ECU in each power window regulator motor assembly. As a result, the power window regulator motor assembly open all of the power windows.
Window open warning function (when approaching a tunnel)	Displays a message on the multi-information display if any window is open when the vehicle is approaching a tunnel.
Window open warning function	When the power switch is turned from on (IG) to off and the driver door is opened with the power window open, the buzzer in the combination meter assembly sounds once and a warning message is displayed on the multi-information display.
Diagnosis	Function that allows diagnosis of the power window control system if any of the power window ECUs (built into each power window regulator motor assembly) detects a malfunction in the system.
Fail-safe	Function to disable part of power window control system functions if the pulse sensor in the power window regulator motor assembly has a malfunction. Auto up and down function and remote control function are disabled.

*: This function is set through a customize setting, as it is off by default.
