HOW TO READ CIRCUIT DIAGRAMS

M1901000100919

The circuit of each system from the fuse (or fusible link) to ground is shown. The power supply is shown at
the top and the ground at the bottom to facilitate understanding of how the current flows. Some variations are
included in one circuit diagram. Accordingly, some diagrams may not be applicable for individual vehicles.The
circuit diagrams show the state when switches are operated.

AC106603

Indicates power source.

Indicates that terminal is conne-
cted via a plate in the relay box.

Each circuit diagram consists of
block(s).

Indicates splice point numbers.
These numbers are identical to
those described in "Splice Loca-
tions."

Indicates the circuit name to be
connected. The arrow indicates
the current flow direction.

Indicates the power supply in
the control unit. If no voltage is
displayed, this indicates battery
positive voltage.

An "X" at the end of a connector
number indicates that the conn-
ector is connected to a central-
ized junction that is shown in the
section "Centralized Junction."

Indicates the connector symbol.
Connectors in the circuit diagram
are indicated in numerical order.

Indicates connector number.
The same number is used in the
wiring harness diagram.
Connector and connector numbers
are shown at the lower part of the
page.
Connector numbers not enclosed
by frame indicate the device incor-
porated into wiring harness.

Indicates the circuit name
to be connected. The arrow
indicates the current flow
direction.

Indicates that the diagram contin-
ues at which belongs to the
block in the same circuit.

AG

One-directional arrow indicate
that current flows upwards.

Indicates shield wire.

Indicates the operating conditions
of the engine coolant switch, etc.
