HOW TO FOLLOW TROUBLE DIAGNOSES

Description

INFOID:0000000001691106

NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
• Before performing trouble diagnoses, read the “Work Flow” in each section.
• After repairs, re-check that the problem has been completely eliminated.
• Refer to Component Parts and Harness Connector Location for the Systems described in each section for

identification/location of components and harness connectors.

• When checking circuit continuity, ignition switch should be OFF.
• 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-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.

• Before checking voltage at connectors, check battery voltage.
• After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all

harness connectors are reconnected as they were.

How to Follow Test Groups in Trouble Diagnosis

INFOID:0000000001691107

1.

Test group number and test group title
• Test group number and test group title are shown in the upper portion of each test group.

2.

Work and diagnosis procedure
• Start to diagnose a problem using procedures indicated in enclosed test groups.

3.

Questions and results
• Questions and required results are indicated in test group.

4.

Action
• Next action for each test group is indicated based on result of each question.

Connector symbols

INFOID:0000000001691109

Most of connector symbols in wiring diagrams are shown from the terminal side.
• 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.

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:

Number

Item

Description

1

Power supply

• This means the power supply of fusible link or fuse.

2

Fusible link

• “X” means the fusible link.

3

Number of fusible link/
fuse

• This means the number of fusible link or fuse location.

4

Fuse

• “/” means the fuse.

5

Current rating of fus-
ible link/fuse

• This means the current rating of the fusible link or fuse.

6

Optional splice

• The open circle shows that the splice is optional depending on vehicle application.

7

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-59, "Elec-

trical Units Location"

, 

PG-31, "Harness Layout"

.

8

Splice

• The shaded circle “

” means the splice.

9

Page crossing

• This circuit continues to an adjacent page.

10

Option abbreviation

• This means the vehicle specifications which layouts the circuit between “

”.

11

Relay

• This shows an internal representation of the relay.

12

Option description

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

13

Switch

• This shows that continuity exists between terminals 1 and 2 when the switch is in the A
