2. Basic Diagnostics ProceduresThe most important purpose of diagnostics is to determinewhich part is malfunctioning quickly, to save time and labor.
A: IDENTIFICATION OF TROUBLE SYMPTOMDetermine what the problem is based on the symptom.
B: PROBABLE CAUSE OF TROUBLELook at the wiring diagram and check the system’s circuit.Then check the switch, relay, fuse, ground, etc.
C: 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 wiringharness, poor connectors, etc. If no problems areencountered, check the component parts.
D: CONFIRMATION OF SYSTEM OPERATIONAfter repairing, ensure that the system operates properly.
G6M0206
E: INSPECTION1. VOLTAGE MEASUREMENT1) Using a voltmeter, connect the negative lead to a goodground point or negative battery terminal and the positivelead to the connector or component terminal.2) Contact the positive probe of the voltmeter on connec-tor (A).The voltmeter will indicate a voltage.3) Shift the positive probe to connector (B). The voltmeterwill indicate no voltage.With test set-up held as it is, turn switch ON. The voltme-ter will indicate a voltage and, at the same time, the lightwill come on.4) The circuit is in good order. If a problem such as a lampfailing to light occurs, use the procedures outlined above totrack down the malfunction.

2. CIRCUIT CONTINUITY CHECKS1) Disconnect the battery terminal or connector so there isno voltage between the check points.Contact the two leads of an ohmmeter to each of the checkpoints.If the circuit has diodes, reverse the two leads and checkagain.2) Use an ohmmeter to check for diode continuity.When contacting the negative lead to the diode positiveside and the positive lead to the negative side, there shouldbe continuity.When contacting the two leads in reverse, there should beno continuity.
3) Symbol “o—o” indicates that continuity exists betweentwo points or terminals. For example, when a switch posi-tion is “3”, continuity exists among terminals 1, 3 and 6, asshown in table below.

3. HOW TO DETERMINE AN OPEN CIRCUIT1) Voltmeter methodAn open circuit is determined by measuring the voltagebetween respective connectors and ground using avoltmeter, starting with the connector closest to the powersupply. The power supply must be turned ON so that cur-rent flows in the circuit. If voltage is not present between aparticular connector and ground, the circuit between thatconnector and the previous connector is open.
G6M0209
2) Ohmmeter methodDisconnect all connectors affected, and check continuity inthe wiring between adjacent connectors. When the ohm-meter indicates “infinite”, the wiring is open.
G6M0210
4. HOW TO DETERMINE A SHORT-CIRCUIT1) Test lamp methodConnect a test lamp (rated at approximately 3 watts) inplace of the blown fuse and allow current to flow throughthe circuit. Disconnect one connector at a time from thecircuit, starting with the one located farthest from the powersupply. If the test lamp goes out when a connector isdisconnected, the wiring between that connection and thenext connector (farther from the power supply) is shorted.
G6M0211
2) Ohmmeter methodDisconnect all affected connectors, and check continuitybetween each connector and ground. When ohmmeterindicates continuity between a particular connector andground, that connector is shorted.

3. Working Precautions1. PRECAUTIONS WHEN WORKING WITH THEPARTS MOUNTED ON THE 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 during work-ing. Also, in automatic transmission vehicles, keep theselect lever set to the P (Parking) range.3) Be sure the workshop is properly ventilated when run-ning the engine. Further, be careful not to touch the belt orfan while the engine is operating.4) Be careful not to touch hot metal parts, especially theradiator and exhaust system immediately after the enginehas been shut off.
2. PRECAUTIONS IN TROUBLE DIAGNOSIS ANDREPAIR OF ELECTRIC PARTS1) The battery cable must be disconnected from the bat-tery’s (−) terminal, and the ignition switch must be set to theOFF position, unless otherwise required by the diagnos-tics.2) Securely fasten the wiring harness with clamps andslips so that the harness does not interfere with the bodyend parts or edges and bolts or screws.3) When installing parts, be careful not to catch them onthe wiring harness.
G6M0212
4) When disconnecting a connector, do not pull the wires,but pull while holding the connector body.

G6M0213
5) Some connectors are provided with a lock. One type ofsuch a connector is disconnected by pushing the lock, andthe other, by moving the lock up. In either type the lockshape must be identified before attempting to disconnectthe connector.To connect, insert the connector until it snaps and confirmthat it is tightly connected.
G6M0214
6) When checking continuity between connector terminals,or measuring voltage across the terminal and ground,always contact tester probe(s) on terminals from the wiringconnection side. If the probe is too thick to gain access tothe terminal, use “mini” test leads.To check water-proof connectors (which are not accessiblefrom the wiring side), contact test probes on the terminalside being careful not to bend or damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensitive tostrong impacts.Handle them with care so that they are not dropped ormishandled.

F: CONNECTOR SKETCH1. Each connector sketch clearly identifies the
shape and color of a connector as well asterminal locations. Non-colored connectorsare indicated in natural color.
2. When more than two types of connectornumber are indicated in a connector sketch,it means that the same type connectors areused.
G: GROUNDEach grounding point can be located easily byreferring to the corresponding wiring harness.
H: DIODEA symbol is used to indicate a diode.
I: WIRE TRACING ON EXTENDEDWIRING DIAGRAMSFor a wiring diagram extending over at least twopages, a symbol (consisting of the same charac-ters with arrows), as shown below, facilitateswire tracing from one page to the next.A ) A, B ) B
J: SYMBOLS OF WIRE CONNECTIONAND CROSSING
Symbol Refers to wires which areconnected and branchedat the “dot” point.
Symbol Refers to wires which arecrossed but not con-nected.
K: POWER SUPPLY ROUTINGA symbol is used to indicate the power supply ineach wiring diagram.“MB-5”, “MB-6”, etc., which are used as powersupply symbols throughout the text, correspondwith those shown in the POWER SUPPLYROUTING in the wiring diagram.Accordingly, using the POWER SUPPLY ROUT-ING and wiring diagrams permits service per-sonnel to understand the entire electricalarrangement of a system.
L: S.M.J.A symbol is used to indicate the terminalarrangement of the super multiple junction. TheS.M.J. is not shown in respective wiring dia-grams but is indicated on the next page.
SYMBOLS AND ABBREVIATIONSA number of symbols and abbreviations are usedin each wiring diagram to easily identify parts orcircuits.
