When checking for a harness short-circuit (short-circuit to
earth) , openone end of the harness and then check for
continuity between theother end adearth:If there is
continuity,theharnessisshort-circuitedtoearthand
should be repaired.
Useananalogvoltmeter resistor(orcircuittester)
when inspecting the continuity.
If the impressed voltageisnot normal even ifwire is
normal, change the engine control nuit ad inspect again.
Usedigital voltmeter (ora circuit tester) when measur-
ing the voltage.Use an analog voltmeter, however, when
inspecting the power transistor drive voltage
ENGINE WARNING LAMP (CHECK ENGINE LAMP)
Amongtheself-diagnosis items,enginewarning lamp
comes
on to notify the driver of the emission control items
when an irregularity is detected.
However, when an irregular signal returns to normal and the
engine control unit judges that it has returned to normal, the
engine warning lamp goesout.
Moreover ,when the ignitionswitch is turned off,the lamp
goes outEven if the ignition switch is turned on again, the
lamp doesnot comeon until the irregularity is detected.
Here,immediately after the ignition switch isturnonthe
engine warning lamp is lit for 5 seconds to indicated that the
engine warning lamp operates normally.

Caution
Engine warning lamp will come o when the line of ter-

it is not abnormal:
