Splice

The shaded circle shows that the splice is always on the vehicle.

9

Page crossing

This arrow shows that the circuit continues to an adjacent page.

The A will match with the A on the preceding or next page.

10

Common connector

The dotted lines between terminals show that these terminals are part of the same connector.

11

Option abbreviation

This shows that the circuit is optional depending on vehicle application.

12

Relay

This shows an internal representation of the relay. For details, refer to 

PG-7, "STANDARD-

IZED RELAY"

 .

13

Connectors

This shows that the connector is connected to the body or a terminal with bolt or nut.

14

Wire color

This shows a code for the color of the wire.

B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light Green

BR = Brown
OR = Orange
P = Pink
PU = Purple
GY = Gray
SB = Sky Blue
CH = Dark Brown
DG = Dark Green

When the wire color is striped, the base color is given first, followed by the stripe color as shown 
below:
Example: L/W = Blue with White Stripe

15

Option description

This shows a description of the option abbreviation used on the page.

16

Switch

This shows that continuity exists between terminals 1 and 2 when the switch is in the A posi-
tion. Continuity exists between terminals 1 and 3 when the switch is in the B position.

17

Assembly parts

Connector terminal in component shows that it is a harness incorporated assembly.

18

Cell code

This identifies each page of the wiring diagram by section, system and wiring diagram page 
number.

19

Current flow arrow

Arrow indicates electric current flow, especially where the direction of standard flow (vertically 
downward or horizontally from left to right) is difficult to follow.

A double arrow “ 

 ” shows that current can flow in either direction depending on circuit 

operation.

20

System branch

This shows that the system branches to another system identified by cell code (section and 
system).

21

Page crossing

This arrow shows that the circuit continues to another page identified by cell code.

The C will match with the C on another page within the system other than the next or preced-
ing pages.

22

Shielded line

The line enclosed by broken line circle shows shield wire.

Switch Positions

Switches are shown in wiring diagrams as if the vehicle is in the “nor-
mal” condition.
A vehicle is in the “normal” condition when:

Ignition switch is OFF.

Doors, hood and trunk lid/back door are closed.

Pedals are not depressed.

Parking brake is released.

23

Component box in 
wave line

This shows that another part of the component is also shown on another page (indicated by 
wave line) within the system.

24

Component name

This shows the name of a component.

25

Connector number

This shows the connector number.

The letter shows which harness the connector is located in.

Example: M : main harness. For detail and to locate the connector, refer to 

PG-33, "HAR-

NESS LAYOUT"

 . A coordinate grid is included for complex harnesses to aid in locating con-

nectors.

26

Ground (GND)

The line spliced and grounded under wire color shows that ground line is spliced at the 
grounded connector.

27

Ground (GND)

This shows the ground connection. For detailed ground distribution information, refer to 

PG-

17, "GROUND"

 .

28

Connector views

This area shows the connector faces of the components in the wiring diagram on the page.

29

Common component

Connectors enclosed in broken line show that these connectors belong to the same compo-
nent.

30

Connector color

This shows a code for the color of the connector. For code meaning, refer to wire color codes, 
Number 14 of this chart.

31

Fusible link and fuse 
box

This shows the arrangement of fusible link(s) and fuse(s), used for connector views of the 
power supply routing. Refer to 

PG-9, "POWER SUPPLY ROUTING"

 .

The open square shows current flow in, and the shaded square shows current flow out.

32

Reference area

This shows that more information on the SMJ (Super Multiple Junction), Electrical Units, etc. 
exists on the at the end of the manual. Refer to "Reference Area" for details.

HOW TO USE THIS MANUAL

Detectable Lines and Non-detectable Lines

In some wiring diagrams, two kinds of lines, representing wires, with
different weight are used.

A line with regular weight (wider line) represents a “detectable
line for DTC (Diagnostic Trouble Code)”. A “detectable line for
DTC” is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.

A line with less weight (thinner line) represents a “non-detect-
able line for DTC”. A “non-detectable line for DTC” is a circuit in
which ECM cannot detect its malfunctions with the on board
diagnostic system.
