The car is in use process, inevitably failure. For experienced drivers, usually one step to find the crux of the problem. Most people in the face of failure often at a loss what to do. Now try to find fault.
The vehicle fault can be divided into three parts: one is the circuit fault; two is the three circuit fault; driving system fault, such as steering, braking and driving part etc.. Among them, the circuit fault is divided into high voltage circuit and low-voltage circuit fault. In practical use, the fault of the vehicle is about 60% circuit failure, 30% in the oil circuit, most of these failures can be ruled out of their own. Only about 10% is the driving system failure, which is a mechanical failure, most of the time when the vehicle can travel, should go to the nearest special maintenance station repair.
When you are driving in the failure, one should not worry, two is not busy hands, first look at the relevant fault indicator to reflect the situation. Jingxiaxinlai, analyze the fault phenomenon, ask a few why? Method of judgment and identification of oil circuit fault has two: one is driving on the way is stalled suddenly or slowly flameout, suddenly turn off mostly circuit fault; slowly flameout, or the vehicle continuously "jump" phenomenon, mostly circuit fault. The two is the "test fire", such as the high pressure cylinder, no fire fire is the circuit failure, such as high-pressure fire, problems in oil. The mechanical faults are mostly associated with abnormal sound, the sound varies with the speed and stop sound disappeared, there is no direct relationship with the oil circuit fault.
"Piecewise negative method", "focus" will be locked in a specific place, first understand is what kind of fault, to check whether the abnormal external. Such as wire or open circuit, short circuit, connecting part has loose; no wires burned taste of the engine, oil pipeline or oil etc..
It is worth mentioning that the car now mostly EFI car, electronic control of combustion, less failure, contrary to the old carburetor car fault probability. Remember, the EFI cars such as circuit failure, often requires a dedicated computer tester, the driver should not do it yourself, so as not to damage the circuit.
