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
[A]: System Title
[B]: Indicates a Relay Block. No shading is used and
only the Relay Block No. is shown to distinguish it
from the J/B
Example : Indicates Relay Block No.1
[C]: ( ) is used to indicate different wiring and
connector, etc. when the vehicle model, engine
type, or specification is different.
[D]: Indicates related system.
[E]: Indicates the wiring harness and wiring harness
connector. The wiring harness with male terminal is
shown with arrows (
).
Outside numerals are pin numbers.
Female Male ( )
The first letter of the code for each wiring harness
and wiring harness connector(s) indicates the
component's location, e.g, ºEº for the Engine
Compartment, ºIº for the Instrument Panel and
Surrounding area, and ºBº 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.
[F]: Represents a part (all parts are shown in sky blue).
The code is the same as the code used in parts
position.
[G]: 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.
3C indicates
that it is inside
Junction Block
No.3 Example:

[H]: When 2 parts both use one connector in common,
the parts connector name used in the wire routing
section is shown in square brackets [ ].[I]: Indicates the wiring color.
Wire colors are indicated by an alphabetical code.
B = Black W = White BR = Brown
L = Blue V = Violet SB = Sky Blue
R = Red O = Orange LG = Light Green
P = Pink Y = Yellow GR = Gray
G = Green
The first letter indicates the basic wire color and the
second letter indicates the color of the stripe.
Example: L ± Y

(Blue)Y
(Yellow)
[J]: Indicates a wiring Splice Point (Codes are ºEº for the
Engine Room, ºIº for the Instrument Panel, and ºBº
for the Body).
The Location of splice Point I 5 is indicated by the
shaded section.
[K]: Indicates a shielded cable.
[L]: Indicates the pin number of the connector.
The numbering system is different for female and
male connectors.
Example :
Numbered in order
from upper left to
lower rightNumbered in order
from upper right to
lower left
Female Male
[M]: Indicates a ground point.
The first letter of the code for each ground point(s)
indicates the component's location, e.g, ºEº for the
Engine Compartment, ºIº for the Instrument Panel
and Surrounding area, and ºBº for the Body and
Surrounding area.
[N]: Page No.

Pins used in the system circuit.
Occupied positions, but not
applicable to the system circuit.
Unoccupied positions.
The pins shown are only for the highest grade, or only include those in the specification.
Junction Connector
Short Terminal Same ColorJunction connector (code: J1 to J40) in this manual include a short
terminal which is connected to a number of wire harnesses. Always
perform inspection with the short terminal installed. (When
installing the wire harnesses, the harnesses can be connected to
any position within the short terminal grouping. Accordingly, in
other vehicles, the same position in the short terminal may be
connected to a wire harness from a different part.)
Wire harness sharing the same short terminal grouping have the
same color.
HINT :
B
[O]: Explains the system outline.
[P]: Indicates values or explains the function for reference during troubleshooting.
[Q]: Indicates the reference page showing the position on the vehicle of the parts in the system circuit.
Example : Part ºL4º (Light Failure Sensor) is on page 36 of the manual.
*The letter in the code is from the first letter of the part, and the number indicates its order in parts
starting with that letter.
Example : L 4
Parts is 4th in order
Light Failure Sensor
[R]: Indicates the reference page showing the position on the vehicle of Relay Block Connectors in the system circuit.
Example : Connector º1º is described on page 18 of this manual and is installed on the left side of the instrument
panel.
[S]: Indicates the reference page showing the position on the vehicle of J/B and Wire Harness in the system circuit.
Example : Connector º3Cº connects the Instrument Panel Wire and J/B No.3. It is described on page 22 of this
manual, and is installed on the instrument panel left side.
[T]: Indicates the reference page describing the wiring harness and wiring harness connector (the female wiring
harness is shown first, followed by the male wiring harness).
Example : Connector ºIE1º connects the floor wire (female) and Instrument panel wire (male). It is described on
page 42 of this manual, and is installed on the left side kick panel.
[U]: Indicates the reference page showing the position of the ground points on the vehicle.
Example : Ground point ºBOº is described on page 50 of this manual and is installed on the back panel center.
[V]: Indicates the reference page showing the position of the splice points on the vehicle.
Example : Splice point ºI5º is on the Cowl Wire Harness and is described on page 44 of this manual.
[W]: Indicates connector to be connected to a part (the numeral indicates the pin No.) Explanation of pin use.
[X]: Connector Color
Connectors not indicated are milky white in color.
