4. INSPECT POWER WINDOW REGULATOR MOTOR
(a) Inspect the regulator motor operation.
HINT:
Driver’s side and rear RH regulator motors should be in-
spected in the same procedure.
Passenger’s side and rear LH regulator motors should be
inspected in the same procedure.
(1) Check that the motor operates smoothly when the
battery positive voltage is applied to each terminal
of the connector.
Standard [Driver ’s side and rear RH side]:
Measuring condition Operational direction
Battery positive (+) Terminal – 4
Battery negative (–) Terminal – 5
Battery positive (+) Terminal – 5
Battery negative (–) Terminal – 4
Clockwise toward driving axis
Counterclockwise toward driving axis
Standard [Front passenger’s side and rear LH side]:
Measuring condition Operational direction
Battery positive (+) Terminal – 5
Battery negative (–) Terminal – 4
Battery positive (+) Terminal – 4
Battery negative (–) Terminal – 5
Clockwise toward driving axis
Counterclockwise toward driving axis
If the result is not as specified, replace the motor.
Fully Closed Position
(b) Inspect the PTC operation inside the 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 T OYOTA electrical tes-
45
ter in the wire harness of terminal 4 or 5.
NOTICE:
Match the arrow mark of the probe with the current direc-
B59333
tion.
(2) Set the door glass in the fully closed position.
(3) When 60 seconds have elapsed after the door
glass is fully closed, check how long it takes for the
current to change 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 af-
ter the inspection of the current cut–off, check that
the door glass goes down when the power window
regulator switch is turned DOWN.
If the result is not as specified, replace the motor.

5. INSPECT RELAY (Making: P/W)
(a) Remove the power window relay from the instrument pan-
el J/B.
(b) Inspect the power window relay.
Condition Terminal No. Specified condition
Constant 1 ⇔ 2 Continuity
B16200
Apply B+ between
Terminals 1 and 2
If the result is not as specified, replace the relay.
