WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: INITIALIZATION (2008 Sequoia)

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 the different operation learned value of the door glass movement speed. 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 .

(a) Initialization procedures when replacing the power window regulator motor with 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 power window does not fully open.

(2) Fully close the power window by fully pulling the power window switch, and hold the switch up 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 the initialization is complete.

2. INITIALIZE BACK DOOR POWER WINDOW CONTROL SYSTEM (BACK DOOR POWER WINDOW REGULATOR MOTOR)

The back door power window motor must be reset (pulse sensor initialized) when the battery has been disconnected, when the back door ECU, the wire harness, the back door power window regulator, or the back door power window motor has been replaced or removed, and when the ECU-B1 fuse (7.5 A), the ECU-IG No. 2 fuse (7.5 A), or the POWER No. 5 fuse (20 A) has been replaced. Functions such as back door AUTO UP/DOWN, jam prevention, and remote UP/DOWN are disabled until the motor is initialized again.

(a) Push the DOWN switch (MANUAL DOWN or AUTO DOWN) to lower the back door power window until it is about one-quarter open.

Skip this step if the back door window has already been lowered to this position.

(b) Fully close the back door power window by pulling up the switch (AUTO UP) and then hold the switch up for an additional 1 second or more to reset the power window motor and complete the initialization.

(c) If the back door power window opens after the held switch is released, then the reset failed. Repeat the reset procedure again.

(d) If the reset procedure was attempted but the back door power window stops or opens when the switch is pulled up, then disconnect the negative (-) battery terminal for 10 seconds or more and repeat the reset procedure again.

(e) If the back door power window motor cannot be reset through the above steps, pull and hold the AUTO UP switch for 12 seconds after the back door power window has fully closed.

If the switch is operated for too long, the back door power window may be deactivated by the Positive Temperature Coefficient (PTC) resistor, and continued use of the switch may temporarily deactivate AUTO operation. In these cases, wait a while and perform the reset operation again.
