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.

ACX02361

Indicates power source.

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

Each circuit diagram consists of
block(s). The blocks are divided
by page number.

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

Indicates connector number.
The same number as 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 mame 
to be connected. The arrow
indicatesthe current flow 
direction.

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

AB

Indicates shield wire.

Indicates that current 
flows upwards.

ACX02362AC

Indicates that the terminal is a
spare one if the device (sensor
in this case) is not provided.

Indicates representative vehicle 
body ground point. (Same 
number as that of ground point in 
GROUNDING LOCATION).

Indicates harness junction where
wire diameter or color changes.

In case two or more connectors
are connected to the same de-
vice, markings indicating the 
same connector are connected
by a broken line.

Indicates terminal number.

Indicates that the diagram comes
from        which belongs to the
       block in the same circuit.        

A broken line indicates that these
connectors are the same interm-
ediate connectors.

Indicates a wiring connector which
is inside the equipment and which
is not shown in the wiring harness
configuration diagram. 

Indicates intersections at
which the lead wires are
not connected.

Indicates intersections at
which the lead wires are
connected.

Indicates input/output 
to/from control unit 
(current flow direction).

Input Output

Input/
output

Indicates current flow downward
or upward as controlled by the 
control unit.

marking

1

The male and female terminals 
are indicated as shown. The 
connector with male terminal(s) 
is called as male connector and 
indicated by two connector 
contour lines, while the 
connector with female 
terminal(s) is called as female 
connector and indicated by 
single connector contour line.

The symbol indicates the 
connector is viewed as shown. 
At a device connection, the 
connector symbol on the device 
side is shown. For an 
intermediate connector, the 
male connector symbol is 
shown. For spare connectors 
and check connectors, no 
device is connected, and so the 
harness-side connector symbol 
is shown for these connectors. 
For the data link connector, its 
contents differ from the previous 
description. Refer to "scan tool 
operation instruction" in detail.
