The most important purpose of diagnostics is to
quickly determine which part is malfunctioning, to
save time and labor.
2. IDENTIFICATION OF TROUBLE SYMPTOM
Determine what the problem is based on the symptom.
3. PROBABLE CAUSE OF TROUBLE
Look at the wiring diagram and check the system’s
circuit. Then check the switch, relay, fuse, ground,
etc.
4. LOCATION AND REPAIR OF TROUBLE
1) Using the diagnostics, narrow down the causes.
2) If necessary, use a voltmeter, ohmmeter, etc.
3) Before replacing certain component parts
(switch, relay, etc.), check the power supply,
ground, for open wiring harness, poor connectors,
etc. If no problem is encountered, check the component parts.
5. SYSTEM OPERATION CHECK
After repairing, ensure that the system operates
properly.
B: BASIC INSPECTION
1. VOLTAGE MEASUREMENT
1) Using a voltmeter, connect the negative lead to a
good ground point or negative battery terminal and
the positive lead to the connector or component terminal.
2) Contact the positive lead of the voltmeter on
connector (A). The voltmeter will indicate a voltage.
3) Shift the positive lead to connector (B). The voltmeter will indicate no voltage.

supply
FUSE
Switch
Light
5) The circuit is in good order. If a problem such as
a light failing to illuminate occurs, use the procedures outlined above to track down the malfunction.
2. CIRCUIT CONTINUITY CHECKS
1) Disconnect the battery terminal or connector so
there is no voltage between the check points.
Contact the two leads of an ohmmeter to each of
the check points.
If the circuit has diodes, reverse the two leads and
check again.
2) Use an ohmmeter to check for diode continuity.
When contacting the negative lead to the diode
positive side and the positive lead to the negative
side, there should be continuity.
When contacting the two leads in reverse, there
should be no continuity.
Continuity No continuity
WI-02740
3) The symbol“ — ” indicates that continuity
exists between two points or terminals. For example, when a switch position is at “3”, continuity exists among terminals 1, 3 and 6, as shown in the
table below.

same time, the light will come on.

3. HOW TO DETERMINE AN OPEN CIRCUIT
1) WITH VOLTMETER:
An open circuit is determined by measuring the
voltage between respective connectors and ground
using a voltmeter, starting with the connector closest to the power supply. The power supply must be
turned ON so that current flows in the circuit. If voltage is not present between a particular connector
and ground, the circuit between that connector and
the previous connector is open.
Open circuit
WI-09860
2) WITH OHMMETER:
Disconnect all connectors affected, and check continuity in the wiring between adjacent connectors.
When the ohmmeter indicates “infinite”, the wiring
is open.
Open circuit
4. HOW TO DETERMINE A SHORT CIRCUIT
1) WITH TEST LIGHT:
Connect a test light (rated at approx. 3 watts) in
place of the blown fuse and allow current to flow
through the circuit. Disconnect one connector at a
time from the circuit. Starting with the one located
farthest from the power supply. If the test light goes
out when a connector is disconnected, the wiring
between that connector and the next connector
(farther from the power supply) is shorted.

Shorted wiring

WI-02744
2) WITH OHMMETER:
Disconnect all affected connectors, and check continuity between each connector and ground. When
the ohmmeter indicates continuity between a particular connector and a ground, that connector is
shorted.

C: HOW TO READ WIRING DIAGRAMS
1. WIRING DIAGRAM
The wiring diagram of each system is illustrated so
that you can understand the path through which the
electric current flows from the battery.
Sketches and codes are used in the diagrams.
They should read as follows:
•Each connector and its terminal position are indicated by a sketch of the connector in a disconnected state which is viewed from the front.

•The number of poles or pins, presence of a lock are indicated in the sketch of each connector. In the
sketch, the highest pole number refers to the number of poles which the connector has. For example, the
sketch of the connector shown in figure indicates the connector has 9 poles.

•The allowable current changes with ambient
temperature. Also, it changes if a bundle of more

•Each connector number shown in the wiring diagram corresponds to that in the wiring harness. The
location of each connector in the actual vehicle is
determined by reading the first character of the

Working Precautions
WIRING SYSTEM
2. Working Precautions
A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
1) When working under a vehicle which is jackedup, always be sure to use rigid rack.
2) The parking brake must always be applied during working. Also, in automatic transmission vehicles, keep the select lever set to the P (Parking)
range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, especially the radiator and exhaust system immediately after the engine has been turned off.
B: PRECAUTIONS IN TROUBLE DI-
AGNOSIS AND REPAIR OF ELECTRIC PARTS
1) The battery cable must be disconnected from
the battery’s (–) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere with
the body end parts or edges and bolts or screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull the
wires, but pull while holding the connector body.
5) Some connectors are provided with a lock. One
type of such a connector is disconnected by pushing the lock, and the other, by moving the lock up.
In either type the lock shape must be identified before attempting to disconnect the connector.
To connect, insert the connector until it snaps and
confirm that it is connected securely.
EXAMPLE
WI-02758
6) When checking continuity between connector
terminals, or measuring voltage across the terminal
and ground, always contact tester probe(s) on terminals from the wiring connection side. If the probe
is too thick to gain access to the terminal, use “mini”
test leads.
To check water-proof connectors (which are not
measurable from the wiring side), contact test
probes on the terminal side. Be careful not to bend
or damage the terminals.
WI-02757
WI-09366
7) Sensors, relays, electrical unit, etc., are sensitive to strong impacts.
Handle them with care so that they are not dropped
or mishandled.
