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 overall connections are required, see the Overall Wiring Diagram

at the end of this manual.

SYSTEM OUTLINE

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 ªMANUAL UPº OPERATION BY MASTER SW

HOLDING MANUAL SW (DRIVER'S) ON ªUPº 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 ªMANUAL DOWNº OPERATION, CURRENT FLOWS IN THE REVERSE DIRECTION BECAUSE THE TERMINALS WHERE IT FLOWS ARE CHANGED).

2.DRIVER'S WINDOW ªAUTO DOWNº OPERATION BY MASTER SW

ONCE THE ªAUTO DOWNº BUTTON OF THE MASTER SW IS PUSHED, THE CURRENT FLOWS TERMINAL 9 OF THE POWER WINDOW CONTROL RELAY 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 ªUPº POSITION WHILE OPERATING AUTO DOWN. THE CURRENT FROM TERMINAL 3 OF THE MASTER SW ASSINGP 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 ªUPº, 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 7 TERMINAL 1 OF THE MASTER SW TERMINAL 4 TO GROUND. THE MOTOR RUNS TO RAISE THE WINDOW. RELEASING THIS SW, THE ROTATION OF MOTOR IS STOPPED AND WINDOW STOPS AT THE DESIRED POINT.

SWITCHING THE WINDOW LOCK SW IN ªLOCKº POSITION, THE CIRCUIT IS OPENED AND STOPS THE MOTOR ROTATION.

(FOR THE DOWN OPERATION, CURRENT FLOWS IN THE REVERSE DIRECTION BECAUSE THE TERMINALS WHERE IT FLOWS ARE CHANGED).

5.PASSENGER'S WINDOW DOWN OPERATION (POWER WINDOW SW)

HOLDING POWER WINDOW SW ON ªDOWNº, THE CURRENT FLOWS FROM TERMINAL 8 OF THE POWER WINDOW SW TERMINAL 9 TERMINAL 1 OF THE MOTOR TERMINAL 2 TERMINAL 4 OF THE POWER WINDOW SW TERMINAL 3 TERMINAL 6 OF THE MASTER SW TERMINAL 4 TO GROUND. THE MOTOR RUNS TO LOWER THE WINDOW.

(FOR THE UP OPERATION, CURRENT FLOWS IN THE REVERSE DIRECTION BECAUSE THE TERMINALS WHERE IT FLOWS ARE CHANGED).

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.

POWER SOURCE (Power±Load, Reference)

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.

GROUND POINTS

9

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)ªfor A typeº

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.

ªfor B typeº

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.
