NOTE: The initial condition that the customizing function is not chosen by the LEXUS hand-held tester is shown. 
  1. CHECK BASIC FUNCTION (MANUAL OPERATION FUNCTION) 
    1. Turn the ignition switch ON.
    2. Check that the door glass moves up when the power window regulator master switch is pulled UP halfway and moves down when the switch is pushed DOWN halfway.
    3. Check that the door glass moves up when the power window regulator switch is pulled UP halfway and moves down when the switch is pushed DOWN halfway.
    4. Check that the passenger side door glass does not operate when the window lock switch is turned to LOCK.
  2. CHECK AUTOMATIC OPERATION FUNCTION 
    1. Turn the ignition switch ON.
    2. Check that the AUTO UP function operates to fully close the door glass when the power window regulator master switch is pulled UP fully.
    3. Check that the AUTO DOWN function operates to fully open the door glass when the power window regulator master switch is pushed DOWN fully.
    4. Check that the AUTO UP function operates to fully close the door glass when the power window regulator switch is pulled UP fully.
    5. Check that the AUTO DOWN function operates to fully open the door glass when the power window regulator switch is pushed DOWN fully.
    6. Check that the door glass stops when the applicable window switch is pulled UP during AUTO DOWN operation. (However, if the switch is held in the UP position, it will change to manual operation.)
    7. Check that the door glass stops when the applicable window switch is pushed DOWN during AUTO UP operation. (However, if the switch is held in the DOWN position, it will change to manual operation.)
  3. CHECK OPERATION FUNCTION AFTER KEY-OFF 
    1. After turning the ignition switch from ON to OFF, check that each door glass can be operated via the power window regulator master switch. Also, check that operation is disabled after the driver side door is opened then closed once.
    2. When approximately 45 seconds have elapsed after the ignition switch is turned from ON to OFF, check that the power window regulator master switch is unable to operate the door glass.
    3. After turning the ignition switch from ON to OFF with the driver side door open, check that the AUTO UP or AUTO DOWN function keeps operating until the door is fully open or fully closed even when the door is closed in the middle of operation. Also, check that power window operation is disabled after operation has ended.
  4. CHECK WIRELESS OPERATION 
    1. With all the doors closed, have no key inserted in the ignition key cylinder.
    2. Check that each door glass moves down when the UNLOCK switch of the transmitter is kept pressed, for 2.5 seconds or more. Also, check that the door glass stops when the UNLOCK switch is released.
  5. CHECK OPERATION FUNCTION BY DRIVER SIDE DOOR KEY OPERATION (OPERATION INTERLOCKED WITH KEY) 
    1. Check that each door glass moves down when the door lock cylinder is held in the UNLOCK position for 2 seconds or more by key operation. Also, check that the door glass stops when the door lock cylinder is turned back to the original position.
    2. Check that each door glass moves up when the door lock cylinder is held in the LOCK position for 2 seconds or more by key operation. Also, check that the door glass stops when the door lock cylinder is turned back to the original position.
  6. CHECK JAM PROTECTION FUNCTION 
NOTE:
  • Do not check this function using a part of your body such as a hand. Also, pay thorough attention that nothing gets caught by accident in this process. 
  • If the power window regulator motor assembly has just been reset, raise and lower the door glass several times using AUTO operation before performing check. 

HINT:

The jam protection function works during the following UP operations; AUTO UP, UP after key OFF, AUTO UP after key OFF and UP interlocked with key.

  1. Fully open the door glass.
  2. Insert the handle of the hammer when the door glass is almost in the fully closed position.

  3. Try to fully close the door glass with AUTO UP operation, and check that the door glass moves down about 200 mm (7.87 in.) and stops there, so that the hammer handle is not caught.

    HINT:

    The door glass goes down by about 50 mm or for 1 second. However, when the opening between the glass and body is less than 200 mm, the door glass goes down by 200 mm or keeps going down for 5 seconds, and then stops.
