EACH SEAT
CIRCUIT DESCRIPTION
With the ignition switch ON and the window lock switch at NORMAL (except driver side), each regulator
switch drives each power window motor.
NOTICE:
The power window system has a function with a large-scale body multiplex communications. First
of all, inspect the communication function depending on the ºhow to proceed with troubleshootingº,
and check that there is no abnormality in the communication system. Then finally proceed with the
troubleshooting.

(b) Inspect the PTC operation inside the power window regulator motor.
NOTICE:
The inspection should be performed with the power window regulator and door glass installed to the
vehicle.
(1) Set a DC 400 A probe of the electrical tester in the wire harness of terminal 1 or 2.
NOTICE:
Match the arrow mark of the probe with the current direction.
(2) Set the door glass in the fully closed position.
(3) When 60 seconds have elapsed after the door glass is fully closed, check now long the current
takes to charge, from approximately 16 - 34 A into 1 A or less, when the power window switch
is turned UP once again.
Standard: Approximately 4 - 90 seconds
(4) When approximately 60 seconds have elapsed after the inspection of the current cut-off, check
that the door glass goes down when the power window regulator switch is turned DOWN.
