(b) Inspect operation of the PTC inside the power window regulator motor.
NOTICE:
The work must be performed with the power window regu-
lator and door glass installed in the vehicle. (1) Set a electrical tester DC 400 A probe to the wireharness of terminal 4 or 6.
NOTICE:
Match the arrow mark of the probe with the current direc-
tion. (2) Fully close the door glass by operating the powerwindow switch and keep the door glass there for
approximately 60 seconds.
(3) Try to operate the power window past the fully
closed position using the power window switch and
measure the time until the electrical current
changes into 1 A from 16 to 34 A (Inspection of cur-
rent shut±off).
Standard: Less than 1 second
(4) Check that the door glass goes down when the power window regulator switch is pushed DOWN.
If the result is not as specified, replace the regulator sub±assy.
