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 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 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.
Indicates the power supply in the control
unit. If no voltage is displayed, this
indicates SYSTEM voltage.
An "X" at the end of a connector No.
indicates that the connector isconnected
to a centralized junction that is shown
in the section "CENTRALIZED JUNC-
TION".
Indicates that the diagram continues
at which belongs to the

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

How to Read Circuit Diagrams
Indicates connector No. The same
No. as in the wiring harness diagram
is used.
Connector numbers enclosed by
frame are
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 shield wire. Indicate that the current flows
from down to up. Bi-directional
