INSPECTION1. Visual and aural checks

Check relay operation, blower motor rotation, light illumtion, etc. visually or aurally. The flow of current isinvisiblecan be checked by the operation of the parts.

I.

2. Slmple checksFor example, if a headlight does not come on and a faulty or poor grounding is suspected, replace the fuse with.aone or ground the light to the body by a jumper wire to demine which part is responsible for the problem.

3. Checking with instrumentsUse an appropriate instrument in an adequate range and the indication correctly. You must have sufficient knowland experience to handle instruments correctly.

INSPECTION INSTRUMENTSIn inspection, make use of the following instruments.

1. Test lightsA test light consists of a 12V bulb and lead wires. It is to check voltages or shortcircuits.

2. Self-power test lightA self-power test light consists of a bulb, battery and wires connected in series. It is used to check continuigrounding.

3. Jumper wireA jumper wire is used to close an open circuit. Never use oneto connect a power supply directly to a load.

4. VoltmeterA voltmeter is used to measure the circuit voltage. Normally,the positive (red lead) probe is applied to the point of voltagemeasurement and the negative (black lead) probe to the bodyground.

5. OhmmederAn ohmmeter is used to check continuity or measure resis-tance of a switch or coil. If the measuring range has beenchanged, the zero point must be adjusted before measure-ment.

CHECKING SWITCHESIn a circuit diagram, a switch is represented by a symbol and in theidle state.

1. Normal open or normalclose switchSwitches are classified into those which make the circuit openand those which make the circuit closed when off.

2. SWITCH CONNECTIONThis figure illustrates a complex switch. The continbetween terminals at each position is as indicated in table below. ,.

- s tage I -.---J- -LNOTEo---O denotes continuity between terminals.

CHECKING RELAYS1. When current flows through the coil of a relay, its core

magnetized to attract the iron piece, closing (ON) the conat the tip of the iron piece. When the coil current is turned the iron piece is made to return to its original position bspring, opening the contact (OFF). ,.

2. By using a relay, a heavy current can be turned on and by a switch of small capacity. For example, in the circshown here, when the switch is turned on (closed), currflows to the coil of the relay. Then, its contact is turned (closed) and the light comes on. The current flowing at ttime to the switch is the relay coil current only and is vesmall.

3. The relays may be classified into the normal open type and normal close type by their contact construction.

NOTEThe deenergized state means that no current is flowthrough the coil and the energized state means that currenflowing through the coil.

When a normal close type relay as illustrated here is checkedthere should be continuity between terminals (1) and (2) andbetween terminals 3 and 4 when the relay is deenergized,and the continuity should be lost between terminals 3 and 4when the battery voltage is applied to the terminals 1 and 2. Arelay can be checked in this manner and it cannot be determine if a relay is okay or faulty by checking its state only whenit is deenergized (or energized).

CHECKING FUSESA blade type fuse has test taps provided to allow checking ofthe fuse itself without removing it from the fuse block. Thefuse is okay if the test light comes on when its one lead isconnected to the test taps (one at a time) and the other lead isgrounded. (Change the ignition switch position adequately sothat the fuse circuit becomes live.)

CAUTlONS IN EVENT OF BLOWN FUSEWhen a fuse is blown, there are two probable causes as follows: One is that it is blown due to flow of current exceeding its rating.The other is that it is blown due to repeated on/off current flowingthrough it. Which of the two causes is responsible can be easilydetermined by visual check as described below.

(1) Fuse blown due to current exceeding ratingThe illustration shows the state of a fuse blown due to thiscause. In this case, do not replace the fuse with a new one

hastily since a current heavy enough to blow the fuse hasflowed through it. First, check the circuit for shorting andcheck for abnormal electric parts. Only after the correction ofsuch shorting or parts, fuse of the same capacity should beused as a replacement. Never use a fuse of lager capacity thanthe one that has blown. If such a fuse is used, electric parts orwirings could be damaged before the fuse blows in the eventan overcurrent occurs again.

(2) Fuse blown due to repeated current on/offThe illustration shows the state of a fuse blown due to repeated current on/off. Normally, this type of problem occursafter fairly long period of use and hence is less frequent thanthe above type. In this case, you may simply replace with anew fuse of the same capacity.

TROUBLESHOOTINGA circuit consists of the power supply, switch, relay, load, ground,etc. There are various methods to check a circuit including anoverall check, voltage check, shortcircuit check and continuitycheck. Each of these methods is briefly described in the following.

1. VOLTAGE CHECK(1) Ground one lead wire of the test light. If a voltmeter is

used instead of the test light, ground the grounding sidelead wire.(2) Connect the other lead wire of the test light to the

power side terminal of the switch connector. The testlight should come on or the voltmeter should indicate avoltage.

(3) Then, connect the test light or voltmeter to the motorconnector. The test light should not come on, or thevoltmeter should.indicate no voltage. When the switchis turned on in this state, the test light should come on,or the voltmeter should indicate a voltage, with motorstarting to run.

(4) The circuit illustrated here is normal but if there is any

problem such as the motor failing to run, check voltagesbeginning at the connector nearest to the motor untilthe faulty part is identified.

2. CHECKING FOR A SHORT-CIRCUITBecause the fuse has blown, it is probable that there is ashort-circuited circuit. Follow the procedures below tonarrow down the short-circuit location.

I. The wiring diagrams are prepared in such a way that the arrangement of connectors for each vehicle, and therouting of each harness, can be easily understood for each individual wiring section.

Indicates the connector number.The connector number used is the same number as that used for circuit diagrams;these numbers facilitate the location of the connector positions.

The alphabet letter used as the prefix represents the wiring section in which thatsonnector is used; subsequent numerals make up the number that indicatesoarticular characteristics of that individual connector. As a general rule, numbers areassigned clockwise around the wiring diagram.Vote that, if there is a concentration of connectors with the same form (samelumber of pins), the connnectors colors are noted in order to facilitate identification,

METERS ANDGAUGES - Troub leshoot inaTROUBLESHOOTINGOPERATION0 When the ignition key is at the ON position,

the fuel gauge is activated.0 When there is much fuel, the units resistance issmall and the current flowing in the circuit isgreat, so the gauges indicator indicates in theF area.0 When there is little fuel, the units resistance ishigh and the current flowing in the circuit is small,so the gauges indicator indicates in the Earea.

c Engine coolanttemperature gauge >0 When the ignition key is at the ON position,

the engine coolant temperature gauge isactivated.0 When the engine coolant temperature is high, theunits resistance is low and there is a great flowof current in the circuit, so the gauges indicatorindicates in the H area.0 When the engine coolant temperature is low, theunits resistance is high and there is a small flowof current in the circuit, so the gauges indicatorindicates in the C area.

0 Pulses are produced in accordance with the

vehicle speed, and vehicle-speed signals are inputto systems (the 4 A/T system, etc.) that regulateaccording to the vehicle speed.

0 When the ignition switch is at the ON position,the oil pressure gauge is activated.0 When oil pressure is high, the internal contacts ofthe gauge unit are kept closed for a longer periodof time. This causes more current to flow in thecircuit, and the gauge pointer swings to the highpressure side.

l When oil pressure is low, the internal contacts ofthe gauge unit open in a shorter period of time.Therefore, there is less current flowing in thecircuit and the gauge pointer swings to the lowpressure side.

l When the ignition key is set to the ON

position, the gauge indicator will be at "0".l When the engine is started, the indicator will

move from 0 to the minus (--) side, and then,as the boost level increases, it will move to theplus (+) side.

NOTEFor operation of warning light and indicator light,refer to P.8-210 INDICATORS.
