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 the power supply in the control
unit. If no voltage is displayed, this
indicates SYSTEM voltage.
Indicates power take out.
Indicates connector No. The same
No. as in the wiring harness diagram
is used.
Connector numbers enclosed by
frame are indicated with the
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 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.
An “X” at the end of a connector No.
indicates that the connector is connected
to a centralized junction that is shown
in the section “CENTRALIZED JUNC-
TION”.
Indicates the operating condi-
tions of the engine coolant
temperature switch, etc.
Indicates the connector symbol.
Connectors in the circuit diagram are
indicated in numerical order.
Indicates shield wire.
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 that the diagram continues
at
Awhich belongs to the block
in the same circuit.2
Indicate that the current flows
from down to up. Bi-directional
arrows indicate that the
direction of current flow
changes when communication
is in progress.

METER AND GAUGE (See P.B-148,152.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge is activated.
DWhen there is much fuel, the unit’s resistance
is small and the current flowing in the circuit
is great, so the gauge’s indicator indicates in
the “Full” area.
DWhen there is little fuel, the unit’s resistance
is high and the current flowing in the circuit
is small, so the gauge’s indicator indicates in
the “Empty” area.

DWhen the ignition switch is at the “ON” position,
the engine coolant temperature gauge is
activated.
DWhen the engine coolant temperature is high,
the unit’s resistance is low and there is a great
flow of current in the circuit, so the gauge’s
indicator indicates in the “H” area.
DWhen the engine coolant temperature is low,
the unit’s resistance is high and there is a small
flow of current in the circuit, so the gauge’s
indicator indicates in the “C” area.TROUBLESHOOTING HINTS
1. Fuel gauge does not operate, or registers
incorrectly.
(1) The fuel gauge indicates “F” when the fuel
gauge unit (sub) connector is disconnected
and the “1” terminal is earthed.
DCheck fuel gauge.
2. Engine coolant temperature gauge does not
operate, or registers incorrectly.
(1) When the engine coolant temperature
gauge is earthed with its connector
unplugged, it registers “H”.
DCheck engine coolant temperature
gauge unit.
