HOW TO READ THE WIRING DIAGRAMS -Composition and Contents of Wiring DiagramsA-2
COMPOSITION AND CONTENTS OF WIRING DIAGRAMS
(1) This manual consists of wiring harness diagrams, installation locations of individual parts, circuits
diagrams and index.
(2) In each section, all specifications are listed, including optional specifications. Accordingly, some
specifications may not be applicable for individual vehicles.
SectionBasic contents
Wiring harness
configuration
diagramsConnector locations and harness wiring configurations on actual vehicles are illustrated.
Single part
installation positionLocations are shown for each point of relays, electronic control units, sensors, solenoids,
solenoid valves, diodes, inspection connectors, spare connectors, fusible links, fuses, etc. In the
part’s lists, parts are listed in alphabetical order.
Circuit diagramsCircuits from power supply to earth are shown completely, classified according to system. There
is a main division into power circuits, and circuits classified by system. The circuits classified by
system also include operation and troubleshooting hints.
DJunction block
The entire circuit for the junction block is described, because only the part of the junction
block needed is normally shown in each circuit diagram.
DJoint connectors
The internal circuits for all joint connectors are described, because only the part needed
is shown in each circuit diagram.
DPower supply circuits
Circuits from the battery to fusible link, dedicated fuses, ignition switch, general purpose
fuses, etc.
DCircuits classified by system
For each system, the circuits are shown from fuse to earth, excluding the power supply
sections.
DOperation
The standard operation of each system is briefly described, following the route of current
flow.
DTroubleshooting hints
This is a brief explanation of the inspection points that serve as hints when troubleshooting.
Explanations of the circuits controlled by the electronic control unit are omitted. Refer
to the related publications as required.
IndexAll components used are listed by connector number and component name.

CIRCUIT DIAGRAMSB-80
STARTING SYSTEM (See P.B-79.)
OPERATION
When the ignition switch is turned to the ST position,
the starter contacts (magnet switch) turns ON and
the starter motor starts turning over.TROUBLESHOOTING HINTS
1. Starter motor does not turn over at all.
DCheck starter (coil).
DCheck battery terminals for proper contact.
2. Starter motor does not stop rotating.
DCheck starter (magnet switch).

CIRCUIT DIAGRAMSB-85
CHARGING SYSTEM (See P.B-84.)
OPERATION
When engine is stationary
DWhen the ignition switch is turned to the ON
position, current flows the alternator L terminal
and, at the same time, the charge warning lamp
illuminates.
When engine is started and after engine has
started
DWhen the engine is started, the charge warning
lamp goes out because of the charging voltage
begin applied to the alternator L terminal.
DThe battery voltage being applied to the
alternator S terminal is monitored by the voltage
regulator. Therefore, the amount of electricity
produced by the alternator is controlled by
allowing and cutting off the current flowing to
the field coil.
DThe alternator B terminal supplies power to
each load.TROUBLESHOOTING HINTS
1. Charging indicator lamp does not illuminate
when the ignition switch is turned to ON
position, before the engine starts.
DCheck multi-purpose fuse No.(2).
DCheck the bulb.
2. Charging indicator lamp fails to switch off once
the engine starts.
DCheck voltage regulator of alternator.
3. Discharged or overcharged battery.
DCheck voltage regulator of alternator.
4. Charge warning lamp illuminates dimly.
DCheck combination meter diode (for short).
