1. General DescriptionA: WIRING DIAGRAMThe wiring diagram of each system is illustrated sothat you can understand the path through whichthe electric current flows from the battery.Sketches and codes are used in the diagrams.They should read as follows:I Each connector and its terminal position areindicated by a sketch of the connector in a discon-nected state which is viewed from the front.

G6M0193

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

I When one set of connectors is viewed from thefront side, the pole numbers of one connector aresymmetrical to those of the other. When these twoconnectors are connected as a unit, the poleswhich have the same number are joined.

G6M0199

I Electrical wiring harness:The connectors are numbered along with the num-ber of poles, external colors, and mating connec-tions in the accompanying list.I 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 figure.

NOTE:A wire which runs in one direction from a connec-tor terminal sometimes may have a different colorfrom that which runs in the other direction from thatterminal.

H6M0509A

I In wiring diagram, connectors which have no ter-minal number refer to one-pole types. Sketches ofthese connectors are omitted intentionally.

G6M0202

I The table lists the nominal sectional areas andallowable currents of the wires.

CAUTION:I When replacing or repairing a wire, be sureto use the same size and type of the wire whichwas originally used.

NOTE:I The allowable current in the table indicates thetolerable amperage of each wire at an ambienttemperature of 40°C (104°F).I The allowable current changes with ambienttemperature. Also, it changes if a bundle of morethan two wires is used.

2. Basic Diagnostics ProcedureA: BASIC PROCEDURE1. GENERALThe most important purpose of diagnostics is todetermine which part is malfunctioning quickly, tosave time and labor.

2. IDENTIFICATION OF TROUBLESYMPTOMDetermine what the problem is based on the symp-tom.

3. PROBABLE CAUSE OF TROUBLELook at the wiring diagram and check the system’scircuit. Then check the switch, relay, fuse, ground,etc.

4. LOCATION AND REPAIR OF TROUBLE1) 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 problems are encountered, check thecomponent parts.

5. CONFIRMATION OF SYSTEMOPERATIONAfter repairing, ensure that the system operatesproperly.

B: INSPECTION1. VOLTAGE MEASUREMENT1) Using a voltmeter, connect the negative lead toa good ground point or negative battery terminaland the positive lead to the connector or compo-nent terminal.2) Contact the positive probe of the voltmeter onconnector (A).The voltmeter will indicate a voltage.3) Shift the positive probe to connector (B). Thevoltmeter will indicate no voltage.

H6M0510A

6

6-3 [D2A1] WIRING DIAGRAM2. Basic Diagnostics Procedure

4) With test set-up held as it is, turn switch ON.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 suchas a lamp failing to light occurs, use the proce-dures outlined above to track down the malfunc-tion.

2. CIRCUIT CONTINUITY CHECKS1) Disconnect the battery terminal or connector sothere 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.

G6M0207

3) Symbol “q—q” indicates that continuity existsbetween two points or terminals. For example,when a switch position is “3”, continuity existsamong terminals 1, 3 and 6, as shown in tablebelow.

B6M0749

3. HOW TO DETERMINE AN OPENCIRCUIT1) Voltmeter Method:An open circuit is determined by measuring thevoltage between respective connectors andground using a voltmeter, starting with the connec-tor closest to the power supply. The power supplymust be turned ON so that current flows in the cir-cuit. If voltage is not present between a particularconnector and ground, the circuit between thatconnector and the previous connector is open.

G6M0208

2) Ohmmeter method:Disconnect all connectors affected, and check con-tinuity in the wiring between adjacent connectors.When the ohmmeter indicates “infinite”, the wiringis open.

G6M0209

7

[D2B3] 6-3WIRING DIAGRAM2. Basic Diagnostics Procedure

4. HOW TO DETERMINE ASHORTCIRCUIT1) Test lamp method:Connect a test lamp (rated at approximately 3watts) in place of the blown fuse and allow currentto flow through the circuit. Disconnect one connec-tor at a time from the circuit, starting with the onelocated farthest from the power supply. If the testlamp goes out when a connector is disconnected,the wiring between that connection and the nextconnector (farther from the power supply) isshorted.

G6M0210

2) Ohmmeter method:Disconnect all affected connectors, and check con-tinuity between each connector and ground. Whenohmmeter indicates continuity between a particularconnector and ground, that connector is shorted.

G6M0211

3. Working PrecautionsA: PRECAUTIONS WHEN WORKINGWITH THE PARTS MOUNTED ONTHE VEHICLE1) When working under a vehicle which is jacked-up, always be sure to use safety stands.2) The parking brake must always be applied dur-ing working. Also, in automatic transmissionvehicles, keep the select lever set to the P (Park-ing) 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, espe-cially the radiator and exhaust system immediatelyafter the engine has been shut off.

B: PRECAUTIONS IN TROUBLEDIAGNOSIS AND REPAIR OFELECTRIC PARTS1) 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 interferewith the body end parts or edges and bolts orscrews.3) When installing parts, be careful not to catchthem on the wiring harness.4) When disconnecting a connector, do not pullthe wires, but pull while holding the connectorbody.

G6M0212

6-3 [D2B4] WIRING DIAGRAM3. Working Precautions

5) Some connectors are provided with a lock. Onetype 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 identifiedbefore attempting to disconnect the connector.To connect, insert the connector until it snaps andconfirm that it is tightly connected.

G6M0213

6) When checking continuity between connectorterminals, or measuring voltage across the termi-nal and ground, always contact tester probe(s) onterminals from the wiring connection side. If theprobe is too thick to gain access to the terminal,use “mini” test leads.To check water-proof connectors (which are notaccessible from the wiring side), contact testprobes on the terminal side being careful not tobend or damage the terminals.

G6M0214

7) Sensors, relays, electrical unit, etc., are sensi-tive to strong impacts.Handle them with care so that they are not droppedor mishandled.
