HOW TO USE THIS MANUAL
1.Before performing trouble diagnoses, read the “Preliminary Check”, the “Symptom Chart” or the
“Work Flow”.
2.After repairs, re-check that the problem has been completely eliminated.
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
●Letter designations next to test meter probe indicate harness
wire color.
●Connector numbers in a single circle (e.g. M33) indicate har-
ness connectors.
●Connector numbers in a double circle (e.g. F211) indicate com-
ponent connectors.

CONNECTOR SYMBOLS
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.
