SYSTEM CIRCUITS

Electrical circuits of each system are shown from the power supply through

ground points. Wiring connections and their positions are shown and

classified by code according to the connection method. (Refer to the

section, “How to use this manual”).

The “System Outline” and “Service Hints” useful for troubleshooting are

also contained in this section.

GROUND POINTS

Shows ground positions of all the parts described in this manual.

OVERALL

ELECTRICAL

WIRING DIAGRAM

Provides circuit diagrams showing the circuit connections.

HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles

by dividing them into a circuit for each system.

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 Wiring Routing

sections to find each part, junction block and wiring harness connectors, wiring

harness and wiring harness connectors, splice points, 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 Electrical

Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL

* The system shown here is an EXAMPLE ONLY. It is different to the actual

circuit shown in the SYSTEM CIRCUITS SECTION.

A : System Title

J : Indicates the wiring color.

Wire colors are indicated by an alphabetical code.

B : Indicates a Relay Block. No shading is used and only the

Relay Block No. is shown to distinguish it from the J/B.

B = Black

BR = Brown

G = Green

GR = Gray

L = Black

LG = Light Green

O = Orange

P = Pink

R = Red

V = Violet

W = White

Y = Yellow

Example: 1 Indicates Relay Block No. 1.

C : Indicates the connector to be connected to a

part (the numeral indicates the pin No.)

Explanation of pin use.

The first letter indicates the basic wire color and the second

letter indicates the color of the stripe.

Example:

L - Y

(blue) (yellow)

K : Indicates a wiring Splice Point (Codes are “E” for

the Engine Room, “I” for the Instrument Panel,

and “B” for the Body).

The pins shown are only for the highest grade, or only

include those in the specification.

Example:

D : Connector Color Connectors not indicated are milky

white in color:

E : ( ) is used to indicate different wiring and connector, etc.

when the vehicle model, engine type, or specification is

different.

F : Indicates related system.

The Location of Splice Point I 5 is indicated by the shaded

section.

L : Page No.

G : Indicates the wiring harness and wiring harness

connector. The wiring harness with male terminal is

shown with arrows ( ).

M : Indicates a shielded cable.

N : Indicates a ground point.

The first letter of the code for each wiring harness and wiring

harness connector(s) indicates thecomponent’s location, e.g,

“E” for the Engine Compartment, “I” for the Instrument Panel

and Surrounding area, and “B” for the Body and Surrounding

area.

The first letter of the code for each ground point(s) indicates

the component’s location, e.g. “E” for the Engine

Compartment, “I” for the Instrument Panel and Surrounding

area, and “B” for the Body and Surrounding area.

When more than one code has the first and second letters in

common, followed by numbers (e.g, IH1, IH2), this indicates

the same type of wiring harness and wiring harness connector.

O : Indicates the pin number of the connector.

The numbering system is different for female and male

connectors.

H : Represents a part (all parts are shown in sky

blue). The code is the same as the code used in

parts position.

I : Junction Block (The number in the circle is the

J/B No. and the connector code is shown beside

it). Junction Blocks are shaded to clearly

separate them from other parts .

P : When 2 parts both use one connector in common, the parts

connector name used in the wire routing section is shown in

square brackets [ ].

Example:

3B indicates

that it is inside

Junction Block

No. 3.

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 CON-

TROL RELAY THROUGH TERMINAL 3 OF THE MASTER SW

WILL POINT.

(FOR THE “MANUAL DOWN” OPERATION, CURRENT FLOWS IN THE REVERSE DIRECTION BECAUSE THE TERMINALS WHERE IT FLOW 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 FLOW 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 2

TERMINAL 1 OF THE RELAY

TERMINAL 3

TO GROUND . THE

MOTOR CONTINUES THE ROTATION ENABLING TO DESCENT THE WINDOW.

THE WINDOW DESCENDS TO THE END POSITION. THE CURRENT WILL BE 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

HOLDING THE MANUAL SW (DRIVER’S) ON “UP” POSITION IN OPERATING AUTO DOWN. THE CURRENT FROM TERMINAL 3 OF THE MASTER SW PASSING TERMINAL 2

FLOWS TERMINAL 5 OF THE RELAY AND RELEASES THE AUTO DOWN FUNCTION IN THE POWER WINDOW CONTROL RELAY. RELEASING THE HAND FROM SW, WINDOW

STOPS AND CONTINUING ON TOUCHING SW. THE FUNCTION SWITCHES 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 PASSING TERMINAL 6 TO TERMINAL 3 OF THE

POWER WINDOW SW (PASSENGER’S)

TERMINAL 7

TERMINAL 4 TO GROUND . THE MOTOR RUNS TO ASCENT THE WINDOW. RELEASING THIS SW, THE ROTATION OF MOTOR IS

STOPPED AND WINDOW CAN STOP AT WILL PLACE. SWITCHING THE WINDOW LOCK SW IN “LOCK” POSITION, THE CIRCUIT IS OPENED AND STOPPED THE MOTOR ROTA-

TION.

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