WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: INITIALIZATION

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ALL DOORS)) (except TMC Made)

CAUTION:
When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized. Functions such as the auto up/down, jam protection, remote control and key-off operation do not operate if the initialization is not performed.

HINT
When the battery is replaced, it is not necessary to initialize the power window regulator motor assembly.

NOTICE:
* When the power window regulator motor assembly is replaced, DTC B2313 is output. Clear the DTC after the initialization.
* When performing initialization, do not perform any other procedures.
* When performing initialization, use the power window switch of each door to initialize each door window.
* After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used, due to detection of a value different from the operation learned value of the door glass movement speed. In such cases, the auto up function can be reinitialized by repeating the following operation at least 5 times:
(1) Open the power window by fully pushing down the power window regulator master switch assembly or power window regulator switch assembly.
(2) Close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly and holding it at the auto up position.
* If the initialization is not completed properly, the LIN communication system may have a malfunction Initial Inspection and Diagnostic Overview.

(a) Initialization procedure when replacing the power window regulator motor assembly with a new one:

(1) Connect the battery and turn the ignition switch to ON (at this time, the LED on the power window regulator master switch assembly or power window regulator switch assembly blinks to indicate that it is ready for initialization).

(2) Fully open the window by fully pushing down the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully opened.

(3) Fully close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position. The LED on the power window regulator master switch assembly or power window regulator switch assembly stops blinking and illuminates to indicate that the initialization is complete.

(b) Initialization procedure when removing/installing the power window regulator motor assembly:

(1) Connect the battery and turn the ignition switch to ON.

(2) Fully close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 6 seconds or more after the window is fully closed (if the power window does not move or stops halfway even when the switch is fully pulled, release the switch and fully pull it again).

(3) Fully open the window by pushing down the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully opened.

(4) Release the power window regulator master switch assembly or power window regulator switch assembly. Then fully push down and hold the switch for 4 seconds or more.

(5) Fully close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position and complete the initialization.

(c) Initialization procedure when the power window does not fully open:

(1) Connect the battery and turn the ignition switch to ON.

(2) Fully close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 6 seconds or more after the window is fully closed (if the power window does not move or stops halfway even when the switch is fully pulled, release the switch and fully pull it again).

(3) Fully open the window by pushing down the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully opened.

(4) Release the power window regulator master switch assembly or power window regulator switch assembly. Then fully push down and hold the switch for 4 seconds or more.

(5) Fully close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position and complete the initialization.

2. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ALL DOORS)) (for TMC Made)

NOTICE:
* If the power window motor or power window regulator motor 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.
* When performing initialization, use the power window switch of each door to initialize each door window.
* 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.
(1) Disconnect the power window regulator motor connector during power window operation. This will return the motor to the pre-initialized condition.

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 battery and turn the ignition switch to ON.

(b) The indicator on the power window regulator master switch assembly or power window regulator switch assembly will blink.

(c) Fully close the door glass by operating the power window regulator master switch assembly or power window regulator switch assembly. After the door glass stops, hold the power window regulator master switch assembly or power window regulator switch assembly in the AUTO UP position for 1 second or more.

(d) Check that the indicator on the power window regulator master switch assembly or power window regulator switch assembly 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 regulator master switch assembly or power window regulator switch assembly in the AUTO UP position for 1 second after the window closes fully.
