CIRCUIT DIAGRAMSB-147
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.

CIRCUIT DIAGRAMSB-155
FUEL WARNING LAMP (See P.B-156.)
OIL PRESSURE WARNING LAMP (See P.B-157.)
BRAKE WARNING LAMP (See P.B-157.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge unit resistance is small when
the fuel level is high, and the fuel gauge unit
resistance is large when the fuel level is low.
When this resistance rises above a specified
value, the fuel warning lamp illuminates to notify
the driver that the fuel level is low.

DWhen the lubrication system fails after engine
starting, resulting in the oil pressure failing to
build up, the oil pressure switch turns on
causing the oil pressure warning lamp to
illuminate.

DWhen the brake fluid level goes down below
a predetermined level with the ignition switch
in the “ON” position, the brake fluid level switch
is activated or the parking brake switch is turned
on, causing the brake warning lamp to
illuminate.TROUBLESHOOTING HINTS
1. No warning lamps illuminate.
DCheck multi-purpose fuse No.(2).
2. Some warning lamps do not illuminate.
DCheck lamp valve.
DCheck the switches and the gauge unit.

HOW TO USE THIS MANUAL
SCOPE OF MAINTENANCE, REPAIR
AND SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Note, however,
that for engine and transmission-related component
parts, this manual covers only on-vehicle
inspections, adjustments, and the removal and
installation procedures for major components.
For detailed information concerning the inspection,
checking, adjustment, disassembly and reassembly
of the engine, transmission and major components
after they have been removed from the vehicle,
please refer to separate manuals covering the
engine and the transmission.
ON-VEHICLE SERVICE
“On-vehicle Service” is procedures for performing
inspections and adjustments of particularly
important locations with regard to the construction
and for maintenance and servicing, but other
inspection (for looseness, play, cracking, damage,
etc.) must also be performed.
INSPECTION
Under this title are presented inspection and
checking procedures to be performed by using
special tools and measuring instruments and by
feeling, but, for actual maintenance and servicing
procedures, visual inspections should always be
performed as well.
INDICATION OF DESTINATION
General Export and GCC are used for convenience
to indicate destination.
NOTE
(1) “General Export” means territories other than
Europe, GCC, Australia, New Zealand, the
U.S.A. and Canada.
(2) “GCC” indicates countries that are members
of the (Persian) Gulf Cooperation Council of
nations.
(3) In some instances, vehicles with other
specifications may be shipped to some
countries.
DEFINITION OF TERMS
STANDARD VALUE
Indicates the value used as the standard for judging
the quality of a part or assembly on inspection
or the value to which the part or assembly is
corrected and adjusted. It is given by tolerance.
LIMIT
Shows the standard for judging the quality of a
part or assembly on inspection and means the
maximum or minimum value within which the part
or assembly must be kept functionally or in strength.
It is a value established outside the range of
standard value.
REFERENCE VALUE
Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be
completed in a shorter time).
CAUTION
Indicates the presentation of information particularly
vital to the worker during the performance of
maintenance and servicing procedures in order to
avoid the possibility of injury to the worker, or
damage to component parts, or a reduction of
component or vehicle function or performance, etc.
INDICATION OF TIGHTENING TORQUE
Tightening torques (units: N·m) are set to take into
account the central value and the allowable
tolerance. The central value is the target value,
and the allowable tolerance provides the checking
range for tightening torques. If bolts and nuts are
not provided with tightening torques, refer to
P.00-28.
