How to judge your vehicle fault

The car is in use process, hard to avoid failure. For experienced drivers, usually "one-step" find out where the problem is. While most people face fault will often be at a loss what to do. Now try to find fault.

Vehicle fault can be divided into three parts: one is the circuit fault; the two is the circuit fault; three is the drive system failure, such as steering, brake, transmission parts. Among them, the circuit fault is divided into high voltage circuit and a low voltage circuit fault. In actual use, vehicle fault is about 60% circuit fault, 30% in the circuit, the fault can be ruled out most of their own. Only about 10% are driving system fault, the fault belongs to machinery fault, occurs most vehicles can travel, should go to specialRepairRepair station.

When you are driving when a failure occurs in a two, don't worry, not busy hands, first have a look about the malfunction indicator lamp of the reflection. The static under heart to come, to analyze the failure phenomenon, ask why several? Judgment, to distinguish oil circuit fault method has two: one is the road is abrupt flameout flameout flameout or slowly, suddenly mostly circuit fault; but slowly flameout, or vehicle happens ceaselessly "drifting" phenomenon, mostly circuit fault. Two is the "fire test", if there is no central high-pressure cylinder fire, fire, is the circuit fault, such as high-pressure fire, problems in oil. While the mechanical fault are mostly accompanied by abnormal sound, sound with the vehicle speed change, stopping when the sound disappears, and the oil circuit fault has no direct relationship.

"Piecewise negative method", "focus" locked in a specific place, to find out what is the kind of fault, to check whether an external anomalies. If the wire is open circuit, short circuit, connection parts are not loose; there is no wire engine burning paste flavor, oil pipelines have leakage etc..

It is worth recalling, now mostly "EFI car" vehicle, electronic control combustion, fault is less, and the old car carburetor failure probability on the contrary. Need to remember is, EFI cars such as the fault circuit, often require special computer detector, drivers should not own hands, so as not to damage the circuit program.

Recent years the technology’s development had had a great breakthrough, the auto repair I concerned also bring us a big surprise, it’s as well contribute to the automobile’s computerization, this intelligentialize mode have the auto repair step into a brand-new prospects. Automobile service vans will carry the equipment car diagnostic tool required to diagnose the issues with the most current engines and auto electrical systems.

There are varies car diagnostic tool and obd code reader at our vtoolshop are all of high quality. We welcome your inquiry.
