Power Window Control (Diagnostics - Introduction): Other Lexus LX J200

PRECAUTION

1. POWER WINDOW CONTROL SYSTEM PRECAUTIONS WARNING: The power window control system prohibits the auto up/down function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no trouble codes are output. When a power window regulator or a power window regulator motor assembly is replaced, the power window control system must be initialized. 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. In such cases, the auto up function can be resumed by repeating the following operation at least 5 times: Close the power window by fully pulling up the power window switch and holding it at the auto up position. Open the power window by fully pushing down the power window switch. The jam protection function may operate unexpectedly even when the power window control system is normal, due to detection of a value different from the operation learned value when the door glass moving speed changes sharply under any of the following conditions: A power window is being opened or closed while the vehicle is driving on a rough road. A power window is being opened or closed while the door is being opened or closed. A sharp voltage change. NOTE: Do not disconnect the cable from the negative (-) battery terminal while the engine switch is on (IG). Otherwise, DTC B2311 will be output.

INITIALIZATION

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR (ALL DOORS)) WARNING: 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. NOTE: When the power window regulator motor is replaced, DTC B2313 is output. Clear the DTC after the initialization. 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 value different from the 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: Open the power window by fully pushing down the power window switch. 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. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-385260-S41337605402011021400000) . Initialization procedures when replacing the power window regulator motor with a new one: Connect the battery and turn the engine switch on (IG) (at this time, the LED on the power window switch blinks to indicate that it is ready for initialization). 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. 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 stops blinking and illuminates to indicate that the initialization is complete. Initialization procedures when removing/installing the power window regulator motor: Connect the battery and turn the engine switch on (IG). 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). Fully open the window by pushing down the power window switch, and hold the switch for 1 second or more after the window is fully opened. Release the power window switch. Then fully push and hold the switch for 4 seconds or more. 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 and complete the initialization. Initialization procedures when the power window does not fully open: Connect the battery and turn the engine switch on (IG). 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). Fully open the window by pushing down the power window switch, and hold the switch for 1 second or more after the window is fully opened. Release the power window switch. Then fully push and hold the switch for 4 seconds or more. 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 and complete the initialization.
