SYSTEM DESCRIPTION

1. POWER WINDOW CONTROL SYSTEM
DESCRIPTION

(a) The power window control system controls the

power window operation using the power window
regulator motors. The main controls of this system
are the power window regulator master switch,
which is mounted on the driver side door, and the
power window regulator switches, which are
mounted on the passenger side door and rear
doors. Operating a window switch results in
electrical power being transmitted to the
corresponding power window regulator motor.

(b) The power window control system has the following

functions:

Function Outline

Function that causes window to go up while power window switch is

Manual up-and-down function

Driver's door auto up-and-down function *

Jam protection function

Remote control function

Key-off operation function

Key-linked up-and-down function

Diagnosis

Fail-safe

being pulled halfway up and to go down while pushed halfway down.
Window stops as soon as the switch is released.

Function that enables windows of driver's doors to be fully opened or
closed by one press of power window switch.

Function that automatically stops power window and moves it
downward if a foreign object gets jammed in door window during auto­up operation.

Function that allows power window master switch to control MANUAL
up-and-down operations of front passenger door window and rear
door windows.

Function that makes it possible to operate power window for approx.
45 seconds after ignition switch is turned on (ACC) or off, if either front
door is not opened.

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.

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.

A fail-safe function to disable a part of power window functions if pulse
sensor in power window motor has a malfunction:
Driver's door auto up-and-down function and remote control function
are disabled.

5. CHECK JAM PROTECTION FUNCTION

NOTICE:

• The jam protection function can activate when
either the AUTO UP function or MANUAL UP
function is used.

• Limbs, fingers or other body parts should not be
used to test the jam protection function. Do not
allow any body parts to get caught by the moving
window or regulator.

HINT:
The jam protection function can activate when either the
AUTO UP function or MANUAL UP function are used
with the ignition switch ON. The jam protection function
can also activate as long as the driver's door remains
closed, within 45 seconds after the ignition switch is
turned off.

WINDSHIELD / WINDOWGLASS – POWER WINDOW CONTROL SYSTEM

INITIALIZATION

1. INITIALIZE POWER WINDOW REGULATOR MOTOR
FRONT LH (WITH JAM PROTECTION)
NOTICE:

• If the power window motor or power window

regulator assembly is replaced, initialization is
required (initialization is not necessary when the
negative battery terminal is disconnected and
reconnected).

• No other electrical systems should be operated

during initialization. Initialization will be
interrupted if a voltage drop occurs in the power
being supplied to the power window motor.

• Replacing the door glass or door glass run may

cause a difference to exist between the current
door glass position and the position memorized
in the ECU. In this case, the jam protection
function may work improperly. Return the system
to the pre-initialized condition and reinitialize the
system.

HINT:

• The AUTO UP function will not work unless

initialization is completed.

• The indicator on the power window master switch will

blink when the ignition switch is ON, until initialization
has been completed. The indicator will remain on

after initialization is successfully completed.
(a) Connect the negative battery terminal.
(b) Turn the ignition switch on (IG). The ind icator on the

power window master switch will blink.

(c) Fully close the door glass by operating the power

window master switch. After the door glass stops,
hold the power window master switch in the AUTO
UP position for 1 second or more.

(d) Check that the indicator on the power window

master switch remains on.
HINT:
If the indicator does not remain on, this means that
initialization has not been completed successfully . In
this case, lower the door glass at least 50 mm (1.96
in.) and hold the power window master switch in the
AUTO UP position for 1 second after the window
closes fully.

2. TO RETURN THE SYSTEM TO THE PRE-INITIALIZES
CONDITION

Disconnect the power window regulator motor connector
during power window operation. This will return the
motor to the pre-initialized condition.

WINDSHIELD / WINDOWGLASS – POWER WINDOW CONTROL SYSTEM

DTC B2311 Driver Door Motor Malfunction

DESCRIPTION

The portion of the power window control system that is located in the driver door consists of a power
window master switch, regulator, and a motor with an integrated ECU. The driver door power window
regulator motor is controlled by the ECU when the power window master switch is operated (models with
jam protection).
DTC B2311 is set when the ECU for the driver door power window regulator motor assembly
malfunctions.

NOTICE:
The power window control system uses a serial communication protocol (LIN) to communicate
with the main body ECU. Inspect the communication function by following HOW TO PROCEED
WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that
the communication system is functioning properly.

HINT:

• Initialization is required only when the power window regulator motor is replaced. However, replacing
the motor may cause the motor gear to be engaged in a different position. This can cause a difference
to exist between the current door glass position and the position memorized in the ECU. In this case,
the jam protection function may work improperly. Return the system to the pre-initialized condition and
reinitialize the system.

• To return the system to the pre-initialized condition:
Disconnect the power window regulator motor connector during power window operation. This will
return the motor to the pre-initialized condition.

DTC No. DTC Detection Condition Trouble Area

B2311

When either condition below is met:

• The power window regulator motor (on
driver side) malfunctions

• When the ECU in the power widow
regulator motor (on driver side)
determines that the fully closed window
position has deviated approximately 20
mm (0.79 in.) or more from the normal
position

• Battery disconnection when the ignition
switch is on (IG)

• Power window regulator motor (on driver
side)

• Incorrect installation of power window
components

• Overheated power window regulator
motor (on driver side)
