WIRING SYSTEMBasic Diagnostic Procedure
1. Basic Diagnostic Procedure
A: BASIC PROCEDURES
1. GENERAL DESCRIPTION
The most important purpose of diagnostics is to de-termine which part is malfunctioning quickly, to
save time and labor.2. IDENTIFICATION OF TROUBLE SYMP-TOM
Determine what the problem is based on the symp-tom.
3. PROBABLE CAUSE OF TROUBLE
Look at the wiring diagram and check the system’scircuit. 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 com-ponent parts.
5. SYSTEM OPERATION CHECK
After repairing, ensure that the system operatesproperly.
B: BASIC INSPECTION
1. VOLTAGE MEASUREMENT
1) Using a voltmeter, connect the negative lead to agood ground point or negative battery terminal andthe positive lead to the connector or component ter-minal.2) Contact the positive lead of the voltmeter onconnector (A). The voltmeter will indicate a voltage.3) Shift the positive lead to connector (B). The volt-meter will indicate no voltage.
4) With the test set-up held as it is, turn the switchON. The voltmeter will indicate a voltage and, at thesame time, the light will come on.
5) The circuit is in good order. If a problem such asa light failing to illuminate occurs, use the proce-dures outlined above to track down the malfunc-tion.
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 ofthe check points.If the circuit has diodes, reverse the two leads andcheck again.2) Use an ohmmeter to check for diode continuity.When contacting the negative lead to the diodepositive side and the positive lead to the negativeside, there should be continuity.When contacting the two leads in reverse, thereshould be no continuity.
3) Symbol “❍ — ❍” indicates that continuity existsbetween 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 tablebelow.

WIRING SYSTEMBasic Diagnostic Procedure
3. HOW TO DETERMINE AN OPEN CIR-CUIT
1) WITH VOLTMETER:An open circuit is determined by measuring thevoltage between respective connectors and groundusing a voltmeter, starting with the connector clos-est to the power supply. The power supply must be
turned ON so that current flows in the circuit. If volt-age is not present between a particular connectorand ground, the circuit between that connector andthe previous connector is open.
2) WITH OHMMETER:Disconnect all connectors affected, and check con-tinuity in the wiring between adjacent connectors.When the ohmmeter indicates “infinite”, the wiringis open.
4. HOW TO DETERMINE A SHORT CIR-CUIT
1) WITH TEST LIGHT:Connect a test light (rated at approx. 3 watts) inplace of the blown fuse and allow current to flow
through the circuit. Disconnect one connector at atime from the circuit. Starting with the one locatedfarthest from the power supply. If the test light goesout when a connector is disconnected, the wiring
between that connector and the next connector(farther from the power supply) is shorted.
2) WITH OHMMETER:Disconnect all affected connectors, and check con-tinuity between each connector and ground. Whenthe ohmmeter indicates continuity between a par-ticular connector and a ground, that connector isshorted.
C: HOW TO READ WIRING DIA-GRAMS
1. WIRING DIAGRAM
The wiring diagram of each system is illustrated sothat you can understand the path through which theelectric 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 indi-cated by a sketch of the connector in a disconnect-ed state which is viewed from the front.

WIRING SYSTEMBasic Diagnostic Procedure
• The number of poles or pins, presence of a lock are indicated in the sketch of each connector. In thesketch, the highest pole number refers to the number of poles which the connector has. For example, thesketch of the connector shown in figure indicates the connector has 9 poles.
• When one set of connectors is viewed from thefront side, the pole numbers of one connector aresymmetrical to those of the other. When these two
connectors are connected as a unit, the poleswhich have the same number are joined.
• WIRING DIAGRAM:The connectors are numbered along with the num-ber of poles, external colors, and mating connec-tions in the accompanying list.• The sketch of each connector in the wiring dia-gram usually shows the (A) side of the connector.The relationship between the wire color, terminalnumber and connector is described in the figure.
NOTE:A wire which runs in one direction from a connectorterminal sometimes may have a different color from
that which runs in the other direction from that ter-minal.

WIRING SYSTEMBasic Diagnostic Procedure
• In the wiring diagram, connectors which have noterminal number refer to one-pole types. Sketchesof these connectors are omitted intentionally.
• The following color codes are used to indicatethe colors of the wires.
• The wire color code, which consists of two letters(or three letters including Br or Lg), indicates thestandard color (base color of the wire covering) byits first letter and the stripe marking by its secondletter.
• The table lists the nominal sectional areas andallowable currents of the wires.
CAUTION:
When replacing or repairing a wire, be sure touse the same size and type of the wire whichwas originally used.
NOTE:• The allowable current in the table indicates thetolerable amperage of each wire at an ambienttemperature of 40°C (104°F).• The allowable current changes with ambienttemperature. Also, it changes if a bundle of morethan two wires is used.

6. CONNECTOR SKETCH
• Each connector sketch clearly identifies theshape and color of a connector as well as terminallocations. Non-colored connectors are indicated innatural color.• When more than two types of connector numberare indicated in a connector sketch, it means that
the same type connectors are used.

Each grounding point can be located easily by re-ferring to the corresponding wiring harness.
8. DIODE
A symbol is used to indicate a diode.
9. WIRE TRACING ON EXTENDED WIRINGDIAGRAMS
For a wiring diagram extending over at least two
pages, a symbol (consisting of the same characterswith arrows), facilitates wire tracing from one pageto the next.A ←→ A, B ←→ B

WIRING SYSTEMWorking Precautions
2. Working Precautions
A: PRECAUTIONS WHEN WORKINGWITH THE PARTS MOUNTED ONTHE VEHICLE
1) When working under a vehicle which is jacked-up, always be sure to use rigid rack.
2) The parking brake must always be applied dur-ing working. Also, in automatic transmission vehi-cles, keep the select lever set to the P (Parking)range.3) Be sure the workshop is properly ventilatedwhen running the engine. Further, be careful not totouch the belt or fan while the engine is operating.4) Be careful not to touch hot metal parts, especial-ly the radiator and exhaust system immediately af-ter the engine has been turned off.
B: PRECAUTIONS IN TROUBLE DI-AGNOSIS AND REPAIR OF ELEC-TRIC PARTS
1) The battery cable must be disconnected fromthe battery’s (−) terminal, and the ignition switchmust be set to the OFF position, unless otherwiserequired by the diagnostics.2) Securely fasten the wiring harness with clampsand slips so that the harness does not interfere withthe body end parts or edges and bolts or screws.3) When installing parts, be careful not to catchthem on the wiring harness.4) When disconnecting a connector, do not pull thewires, but pull while holding the connector body.
5) Some connectors are provided with a lock. One
type of such a connector is disconnected by push-ing the lock, and the other, by moving the lock up.In either type the lock shape must be identified be-fore attempting to disconnect the connector.
To connect, insert the connector until it snaps andconfirm that it is tightly connected.
6) When checking continuity between connectorterminals, or measuring voltage across the terminaland ground, always contact tester probe(s) on ter-minals from the wiring connection side. If the probeis too thick to gain access to the terminal, use “mini”test leads.To check water-proof connectors (which are notmeasurable from the wiring side), contact test
probes on the terminal side. Be careful not to bendor damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensi-tive to strong impacts.Handle them with care so that they are not droppedor mishandled.
