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.

Determination of Probable Causes
4Repair and Confirmation
Observe the symptom carefully. Check if there are also
other problems.
In determining the probable causes, it is necessary to
study the wiring diagram to understand the circuit as a
system. Knowledge of switches, relays and other parts is
necessary for accurate analysis. The causes of similar
problems in the past must be taken into account.
Troubleshooting is carried out by making step-by-step
checks until the cause is found.
After the problems are corrected, be sure to check that the
system operates correctly. Also check that new problems
have not been caused by the repair.
