HOW TO RESET POWER WINDOW MOTOR (LIMIT SWITCH)
NOTICE:
If the jam protection function is not functioning properly, perform the following procedures.
HINT:
It is necessary to reset the power window motor (in initial position for the limit switch) when separating the
window regulator from the power window motor or operating the window regulator with the door glass not
installed.
(a) Remove the power window motor.
HINT:
Place matchmarks on the power window motor and window regulator gear.
(b) Connect the power window motor and power window switch to the wire harness of the vehicle.
(c) Turn the ignition switch ON.
(d) Press the power window UP switch until the motor completes 6 to 10 rotations (4 seconds of rotation
or more).
(e) Assemble the power window motor and regulator.
HINT:
Install the motor when the regulator arm is below the middle point.
Align the matchmarks on the power window motor and window regulator gear when installing the pow-
er window motor.
(f) Assemble the power window regulator and door glass.
HINT:
Never rotate the motor downward until the completion of the window glass installation.
(g) Connect the power window switch to the wire harness and turn the ignition switch ON.
(h) Repeat UP and DOWN operation several times manually.
(i) Check that AUTO UP " AUTO DOWN automatic operation is normal.
NOTICE:
The jam protection function does not operate immediately after performing reset.
If the jam protection function is triggered and the window lowers after the window has been fully
closed by AUTO UP operation (step i), reset the power window motor again.
(j) Check the power window function.

1 and the negative (±) lead to terminal 4 and check that
the motor turns clockwise.
(b) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to terminal 1 and check that
the motor turns counterclockwise.
If operation is not as specified, replace the back door power
window motor.

(a) Remove the back door ECU with the connectors still con-
nected.
(b) Connect the oscilloscope to terminals A±16 and A±17
and body ground.
(c) Operate the back door power window switch.
(d) Check the signal waveform according to the condition (s)
in the table below.

5. INSPECT JAM PROTECTION FUNCTION
NOTICE:
Be careful not to get any part of your body caught when
checking.
HINT:
When performing resetting of the limit switch, do checking after
repeating up and down of the glass with automatic operation.
(a) Confirmation of AUTO up operation:
Confirm that the window will close fully with AUTO up op-
eration.
(b) Checking operation of the jam protection function:
(1) Raise the window with AUTO up operation and
check that the window goes down when it touches
the inserted handle of the hammer.
(2) Confirm that the window will then stop going down
after about 200 mm (7.87 in).
HINT:
When removing the glass, glass guide, regulator, etc. be sure
to perform a check of the jam protection function.
If the jam protection is not functioning properly, adjust the power
window motor switch and pulse switch.

ADJUSTMENT
1. RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR
NOTICE:
Resetting the power window regulator motor (initializing the pulse sensor) is necessary if: 1) the bat-
tery terminal cable is disconnected; 2) the back door ECU, wire harness, power window regulator
switch, power window regulator assembly and power window regulator motor are replaced or re-
moved/installed; or 3) the P/W fuse is replaced or removed. If resetting is not performed, the master
switch assembly will not be able to operate the AUTO operation function, jam protection function and
remote operation function.
(a) Turn the ignition switch ON.
(b) Open the power window halfway by pressing the power window switch.
(c) Fully pull up on the switch until the power window is fully closed and continue to hold the switch for
at least 1 second.
(d) Check that the AUTO UP/DOWN function operates normally.
If the AUTO UP/DOWN function operates normally, reset operations are complete. If abnormal, follow the
steps (e) to (g) below.
(e) Disconnect the negative battery terminal cable for 10 seconds.
(f) Connect the battery terminal cable.
(g) Perform the steps (a) to (d) again.
