5 INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE)
(a) Inspect the power window regulator motor assy LH (Driver side) operation.
NOTICE:
Do not apply the battery voltage, because the pulse sensor and limit switch could be damaged
if the battery voltage is applied to terminals 2, 3 and 6 of the power window regulator motor con-
nector.
Be sure to reset the power window regulator motor (initial position setting of limit switch) when
the driver's side power window regulator motor is installed to the regulator.
(1) Check that the motor operates smoothly when the
battery positive voltage is applied to each terminal
of the connector.
Standard:
Measuring ConditionOperational Direction
Battery positive - Terminal 5
Battery negative - Terminal 4Clockwise
Battery positive - Terminal 4
Battery negative - Terminal 5Counterclockwise
(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 4 or 5.
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.

(i) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All the con-
nectors in the system are a standard yellow color. If the SRS wire harness becomes discon-
nected or the connector becomes broken, repair or replace it.
2. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (-) terminal cable beforehand to
prevent component and wire damage caused by
accidental short circuits.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal. Remove the battery cable from battery
post.
(3) Clock settings, radio settings, DTCs and other data
are erased when the battery cable is removed. Be-
fore removing the battery cable, record any neces-
sary data.
(4) When disconnecting the battery's negative (-) ter-
minal cable, re-initialize the following systems after
the completion of the operation.
(b) HANDLING OF ELECTRONIC PARTS
(1) Do not open the cover or case of the ECU unless
absolutely necessary. If the IC terminals are
touched, the IC may be rendered inoperative by
static electricity.
(2) To disconnect electronic connectors, pull the con-
nector itself, not the wires.
(3) Be careful not to drop electronic components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced.
(4) When cleaning the engine with steam, protect the
electronic components, air filter and emission-re-
lated components from water.
(5) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(6) When checking the continuity at the wire connector,
insert the tester probe carefully to prevent terminals
from bending.
