M1901000100470

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.

AC106603

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 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 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.

AC106604

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.

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

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.

AB

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

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

Example  C-15-2

Indicates a connector
which is inside the 
equipment, numbered
in order starting from 1.

Indicates the connector number shown in 
the wiring harness configuration diagram.
