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.
