BHOW TO USE THIS
MANUALInstructions on how to use this manual.
CTROUBLE±
SHOOTINGDescribes the basic inspection procedures for electrical circuits.
DABBREVIATIONSDefines the abbreviations used in this manual.
E
GLOSSARY OF
TERMS AND
SYMBOLS
Defines the symbols and functions of major parts.
FRELAY LOCATIONSShows position of the Electronic Control Unit, Relays, Relay Block, etc.
This section is closely related to the system circuit.
GELECTRICAL
WIRING ROUTINGDescribes position of Parts Connectors, Splice points, Ground points, etc.
This section is closely related to the system circuit.
INDEXIndex of the system circuits.
H
SYSTEM CIRCUITS
Electrical circuits of each system are shown from the power supply through ground
points. Wiring connections and their positions are shown and classified by code
according to the connection method. (Refer to the section, ºHow to use this manualº).
The ºSystem Outlineº and ºService Hintsº useful for troubleshooting are also contained
in this section.
IGROUND POINTSShows ground positions of all parts described in this manual.
J
OVERALL
ELECTRICAL
WIRING DIAGRAM
Provides circuit diagrams showing the circuit connections.
KPOWER SOURCE
(Current Flow Chart)Describes power distribution from the power supply to various electrical loads.
LPART NUMBER OF
CONNECTORSIndicates the part number of the connectors used in this manual.

B
The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
