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.
