Toyota Tundra Service Manual: Initialization

INITIALIZATION

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR [for DRIVER AND FRONT PASSENGER SIDE DOORS])

NOTICE:

When the power window regulator motor is reinstalled or replaced, the power window control system must be initialized. Functions such as the AUTO UP/DOWN, jam protection and key-off 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.

NOTICE:

• When performing initialization, do not perform any other procedures.
• 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 door glass movement speed that differs from the speed indicated by the operation learned value. In such cases, the AUTO UP function can be resumed by repeating the following operation at least 5 times:

  (a) Open the power window by fully pushing down the power window switch.

  (b) Close the power window by fully pulling up the power window switch and holding it at the AUTO UP position.

• If the initialization is not completed properly, the LIN communication system may have a malfunction (See page ).

(a) Initialization procedures when replacing the power window regulator motor with a new one.

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

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

(3) Fully close the power window by fully pulling the power window switch, 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 switch changes from blinking to illuminated to indicate that the initialization is complete.

(b) Initialization procedures when removing/installing the power window regulator motor or 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 the power window switch, 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 switch, and hold the switch down for 1 second or more after the window is fully opened.

(4) Release the power window switch. Then fully push and hold the switch 4 seconds or more.

(5) Fully close the power window by fully pulling the power window switch, and hold the switch 1 second or more after the window is fully closed to reset the glass position. This completes the initialization.
