• 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.

< HOW TO USE THIS MANUAL >

HOW TO USE THIS MANUAL

• 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.

HOW TO FOLLOW TROUBLE DIAGNOSES

Description

INFOID:0000000003938040

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.
