WIRING DIAGRAM
Provides circuit diagrams showing the circuit connections.
HOW TO USE THIS MANUAL
This manual provides information on the electrical circuits installed on vehicles by
dividing them into each system circuit.
The actual wiring of each system circuit is shown from the point where the power source
is received from the battery as far as each ground point. (All circuit diagrams are shown
with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit where
the problem was detected (see System Circuit section), the power source supplying
power to that circuit (see Power Source section), and the ground points (see Ground
Points section). See the System Outline to understand the circuit operation.
When the circuit operation is understood, begin troubleshooting of the problem circuit
to isolate the cause. Use Relay Location and Electrical Wire Routing sections to find
each part, junction block and wiring harness connectors, wiring harness and wiring
harness connectors, and ground points of each system circuit. Internal wiring for each
junction block is also provided for better understanding of connection within a junction
block.
Wiring related to each system is indicated in each system circuit by arrows (from
, to ). When o verall connections a re required, see the O verall Wiring Diagram
at the end of this manual.

HOW TO USE THIS MANUAL
P
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 3 OF THE POWER WINDOW MASTER SW, TERMINAL 2 OF THE POWER WINDOW CONTROL RELAY
AND TERMINAL 8 OF THE POWER WINDOW SW THROUGH THE DOOR FUSE.
1. DRIVER’S WINDOW “MANUAL UP” OPERATION BY MASTER SW
HOLDING MANUAL SW (DRIVER’S) ON “UP” POSITION LOCATED IN POWER WINDOW MASTER SW, THE CURRENT FLOWS TO TERMINAL 5 OF THE POWER WINDOW
CONTROL RELAY THROUGH TERMINAL 3 OF THE MASTER SW TERMINAL 2 TO OPERATE A POWER WINDOW CONTROL RELAY. THUS THE CURRENT INSIDE THE RELAY
FLOWS FROM TERMINAL 2 OF THE RELAY TERMINAL 1 TERMINAL 2 OF THE POWER WINDOW MOTOR TERMINAL 1 TERMINAL 4 OF THE RELAY TERMINAL
3 TO GROUND. THE MOTOR TURNS TO RAISE THE WINDOW. RELEASING THIS SW, THE ROTATION OF MOTOR IS STOPPED AND THE WINDOWS STOP AT DESIRED
POINT.
(FOR THE “MANUAL DOWN” OPERATION, CURRENT FLOWS IN THE REVERSE DIRECTION BECAUSE THE TERMINALS WHERE IT FLOWS ARE CHANGED).
2. DRIVER’S WINDOW “AUTO DOWN” OPERATION BY MASTER SW
ONCE THE “AUTO DOWN” BUTTON OF THE MASTER SW IS PUSHED, THE CURRENT FLOWS TERMINAL 9 OF THE POWER WINDOW CONTROL RELA Y THROUGH TERMINAL
3 OF THE MASTER SW TERMINALS 8 AND 9 TO OPERATE THE RELAY. THUS THE CURRENT INSIDE THE POWER WINDOW CONTROL RELAY FLOWS FROM TERMINAL
2 OF THE RELAY TERMINAL 4 TERMINAL 1 OF THE POWER WINDOW MOTOR TERMINAL 2 TERMINAL 1 OF THE RELAY TERMINAL 3 TO GROUND.
THE MOTOR CONTINUES TO ROTATE, ENABLING THEWINDOW TO DESCEND.
WHEN THE WINDOW DESCENDS TO THE END POSITION, THE CURRENT IS CUT OFF TO RELEASE THE AUTO DOWN FUNCTION BASED ON THE INCREASING CURRENT
BETWEEN TERMINAL 2 OF THE RELAY AND TERMINAL 1 IN RELAY.
3. DRIVER’S WINDOW AUTO DOWN RELEASE OPERATION BY MASTER SW
BY HOLDING THE MANUAL SW (DRIVER’S) IN “UP” POSITION WHILE OPERATING AUTO DOWN. THE CURRENT FROM TERMINAL 3 OF THE MASTER SW PASSING THROUGH
TERMINAL 2 FLOWS TO TERMINAL 5 OF THE RELAY AND RELEASES THE AUTO DOWN FUNCTION IN THE POWER WINDOW CONTROL RELAY . RELEASING THE HAND FROM
SW, STOPS THE WINDOW AND CONTINUING TO TOUCH THE SW, SWITCHES THE FUNCTION TO MANUAL UP OPERATION.
4. PASSENGER’S WINDOW UP OPERATION (MASTER SW) AND WINDOW LOCK SW OPERATION
HOLDING PASSENGER’S WINDOW SW (MASTER SW) ON “UP”, THE CURRENT FLOWS FROM TERMINAL 3 OF THE MASTER SW THROUGH TERMINAL 6 TO TERMINAL 3 OF
THE POWER WINDOW SW (PASSENGER’S) TERMINAL 4 TERMINAL 2 OF THE MOTOR TERMINAL 1 TERMINAL 9 OF THE POWER WINDOW SW TERMINAL

HOW TO USE THIS MANUAL
The Power – Load section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits
current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained.
Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the
problem ground quickly. The relationship between ground points ( , , and shown below) can also be
checked this way.

TROUBLESHOOTING
VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the
check point.
Example:
– Ignition SW on
– Ignition SW and SW 1 on
– Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good
ground point or negative battery terminal, and the
positive lead to the connector or component terminal.
This check can be done with a test light instead of a
voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no
voltage between the check points.
(b) Contact the two leads of an ohmmeter to each of the
check points.
If the circuit has diodes, reverse the two leads and check
again.
When contacting the negative lead to the diode positive side
and the positive lead to the negative side, there should be
continuity.
When contacting the two leads in reverse, there should be no
continuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical circuit.
10
FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the
fuse.
(b) Connect a test light in place of the fuse.
(c) Establish conditions in which the test light comes on.
Example:
– Ignition SW on
– Ignition SW and SW 1 on
– Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while
watching the test light.
The short lies between the connector where the test
light stays lit and the connector where the light goes
out.
(e) Find the exact location of the short by lightly shaking
the problem wire along the body.
CAUTION:
Do not open the cover or the case of the ECU and
various computer unless absolutely necessary. (If the
IC terminals are touched, the IC may be destroyed by
static electricity.)
DISCONNECTION OF MALE AND FEMALE
CONNECTORS
To pull apart the connectors, pull on the connector itself, not the
wire harness.
HINT: Check to see what kind of connector you are disconnecting
before pulling apart.

TROUBLESHOOTING
HOW TO REPLACEMENT FOR TERMINAL
(with Terminal Retainer Type)
1. DISCONNECT CONNECTOR
2. DISCONNECT TERMINAL FROM CONNECTOR
(a) “for A type”
Raise the terminal retainer up to the temporally lock
position.
HINT: The needle insertion position varies according
to the connector ’s shape (number of terminals
etc.), so check the position before inserting it.
“for B type”
Open the terminal retainer.
(b) Release the locking lug from terminal and pull the
terminal out from rear.
3. INSTALL TERMINAL TO CONNECTOR
(a) Insert the terminal.
HINT:
1. Make sure the terminal is positioned correctly.
2. Insert the terminal until the locking lug locks firmly.
3. Insert the terminal with terminal retainer in the
temporally lock position.
(b) Push the terminal retainer in to the full lock position.

Above that potential, it passes the
excess voltage. This acts as a
simple voltage regulator.
DISTRIBUTOR, IIA

individual spark plugs.
FUSE
A thin metal strip which burns
through when too much current

high amperage circuits which
burns through on overloads,
thereby protecting the circuit.
FUEL
