HOW TO READ THE WIRING DIAGRAMS -Composition and Contents of Wiring DiagramsA-2
COMPOSITION AND CONTENTS OF WIRING DIAGRAMS
(1) This manual consists of wiring harness diagrams, installation locations of individual parts, circuits
diagrams and index.
(2) In each section, all specifications are listed, including optional specifications. Accordingly, some
specifications may not be applicable for individual vehicles.
SectionBasic contents
Wiring harness
configuration
diagramsConnector locations and harness wiring configurations on actual vehicles are illustrated.
Single part
installation positionLocations are shown for each point of relays, electronic control units, sensors, solenoids,
solenoid valves, diodes, inspection connectors, spare connectors, fusible links, fuses, etc. In the
part’s lists, parts are listed in alphabetical order.
Circuit diagramsCircuits from power supply to earth are shown completely, classified according to system. There
is a main division into power circuits, and circuits classified by system. The circuits classified by
system also include operation and troubleshooting hints.
DJunction block
The entire circuit for the junction block is described, because only the part of the junction
block needed is normally shown in each circuit diagram.
DJoint connectors
The internal circuits for all joint connectors are described, because only the part needed
is shown in each circuit diagram.
DPower supply circuits
Circuits from the battery to fusible link, dedicated fuses, ignition switch, general purpose
fuses, etc.
DCircuits classified by system
For each system, the circuits are shown from fuse to earth, excluding the power supply
sections.
DOperation
The standard operation of each system is briefly described, following the route of current
flow.
DTroubleshooting hints
This is a brief explanation of the inspection points that serve as hints when troubleshooting.
Explanations of the circuits controlled by the electronic control unit are omitted. Refer
to the related publications as required.
IndexAll components used are listed by connector number and component name.

HOW TO READ CIRCUIT DIAGRAMS
The circuit of each system from fuse (or fusible link) to earth is shown. The power supply is shown
at the top and the earth at the bottom to facilitate understanding of the current flow.
Indicates the power supply in the control
unit. If no voltage is displayed, this
indicates SYSTEM voltage.
Indicates power take out.
Indicates connector No. The same
No. as in the wiring harness diagram
is used.
Connector numbers enclosed by
frame are indicated with the
connector symbols at the lower part
of the page.
Connector numbers not enclosed by
a frame indicate components which
are integrated with the harness.
Indicates harness junction point No. for
another system. It corresponds to the
junction point No. indicated on the
destination system circuit diagram.
Indicates the circuit name to be
connected. The arrow indicates the
current flow direction.
An “X” at the end of a connector No.
indicates that the connector is connected
to a centralized junction that is shown
in the section “CENTRALIZED JUNC-
TION”.
Indicates the operating condi-
tions of the engine coolant
temperature switch, etc.
Indicates the connector symbol.
Connectors in the circuit diagram are
indicated in numerical order.
Indicates shield wire.
Indicates that terminal is connected via
a plate in the relay box.
Each circuit diagram consists of
block(s). The blocks are divided by
page number.
Indicates that the diagram continues
at
Awhich belongs to the block
in the same circuit.2
Indicate that the current flows
from down to up. Bi-directional
arrows indicate that the
direction of current flow
changes when communication
is in progress.
