The most of
people think
obd2 complex automobile once go wrong must utilize the especial
auto diagnostic tool, for instance launch x431 diagun, lexia 3 and so on
device or rich experience worker can estimate the breakdown. But they
don't know some common breakdown the person often driving also can
judge.
When you
automobile engine can't work in all probability is the ignition system
go wrong, not automobile fuel system or other system emerging questions.
If accord to the system checks the ignition system carefully generally
don't use the special equipment or tools could find out the breakdown.
Firstly open the ignition switch, if the ampere meter display the
slightly electro-discharge, or the indicator illumined indicate the
circuit is unobstructed and check the Gasoline meter
Launch X431 GX3 whether have the
gasoline. Operate the engine, if the engine move normally, means the
storage battery and starter is nothing goes wrong, on contrary, the
engine move slowly, perhaps because the storage battery had been used up
or the storage battery had been broken. Also have the probable is for
the storage battery binding post comes loose, corroded, and smudged. Or
engine, start switch or engine transmission is broken caused. If the
engine circuit is normal, put aside the state to consider the ignition
system. Like this problem, know some basic automobile structure and
working theory can estimate the problem position by yourself, but have
the practice experience is better. As well know, some simply and common
breakdown without any auto diagnostic tool Launch X431 GX3 can be judge, even the person
don't know much about automobile but frequently face this situation,
it's like we absolutely don't know the medical skill but when we catch a
cold, we can easy judge that's a cold accord to reason and result just
because we face many times. The automobile diagnoses have many similar
places with personal diagnoses, so the word original be used in medical
also be devoted to the automobile inspection.
The auto diagnostic tool like judge malady of device and medicine,
some medicine can cure all of people for this illness, similar with
launch x431 diagun can applied to all of cars. But most of medicine is
accord to the patients' feature and corporeity work. Like as Digimaser 3 , sbb key programmer, elm327, and so on is aim at the different cars and breakdown.
