HOW TO USE THIS MANUAL
3.Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4.Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.
5.When checking circuit continuity, ignition switch should be OFF.
6.Before checking voltage at connectors, check battery voltage.
7.After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES
1.Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in enclosed test groups.
2.Questions and required results
Questions and required results are indicated in bold type in test group.
The meaning of are as follows:
3.Symbol used in illustration
Symbols included in illustrations refer to measurements or procedures. Before diagnosing a problem,
familiarize yourself with each symbol. Refer to "Connector Symbols" in GI Section and "KEY TO SYM-
BOLS SIGNIFYING MEASUREMENTS OR PROCEDURES" below.
4.Action items
Next action for each test group is indicated based on result of each question. Test group number is shown
in the left upper portion of each test group.
HARNESS WIRE COLOR AND CONNECTOR NUMBER INDICATION
There are two types of harness wire color and connector number indication.
TYPE 1: Harness Wire Color and Connector Number are Shown in Illustration
SAIA0256E
a. Battery voltage → 11 - 14V or approximately 12V
b. Voltage : Approximately 0V → Less than 1V

CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from the terminal side.
SAIA0751E

GI-14
< SERVICE INFORMATION >
HOW TO USE THIS MANUAL
• Connector symbols shown from the terminal side are enclosed by
a single line and followed by the direction mark.
• Connector symbols shown from the harness side are enclosed by
a double line and followed by the direction mark.
• Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connector.
For description and how to disconnect, refer to PG section,
“Description”, “HARNESS CONNECTOR”.
• Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

Harness Indication
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 GreenBR = Brown
OR or O = Orange
P = Pink
PU or V (Violet) = Purple
GY or GR = 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 preceding
pages.
22 Shielded line • The line enclosed by broken line circle shows shield wire.
23Component 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 section "Main
Harness", “Harness Layout”. A coordinate grid is included for complex harnesses to aid in lo-
cating connectors.
26 Ground (GND)• The line spliced and grounded under wire color shows that ground line is spliced at the ground-
ed connector.
27 Ground (GND)• This shows the ground connection. For detailed ground distribution information, refer to
"Ground Distribution" in PG section.
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.
31Fusible link and fuse
box• This shows the arrangement of fusible link(s) and fuse(s), used for connector views of "POW-
ER SUPPLY ROUTING" in PG section.
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 Super Multiple Junction (SMJ) and Joint Connectors
(J/C) exists on the PG section. Refer to "Reference Area" for details. Num-
berItem Description

GI-18
< SERVICE INFORMATION >
HOW TO USE THIS MANUAL
• Letter designations next to test meter probe indicate harness (con-
nector) wire color.
• Connector numbers in a single circle M33 indicate harness con-
nectors.
Component Indication
Connector numbers in a double circle F211 indicate component connectors.
Switch Positions
Switches are shown in wiring diagrams as if the vehicle is in the “normal” 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, and
• parking brake is released.
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-detectable
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.
Multiple Switch
The continuity of multiple switch is described in two ways as shown below.
• The switch chart is used in schematic diagrams.
• The switch diagram is used in wiring diagrams.
