First, we must learn to drive car to learn to find their own fault ""
Car in the use of the process, it is inevitable failure. For experienced drivers, usually can be "one step" to find the problem. And most people are helpless in the face of failure. Now learn to look for trouble.
Vehicle failure can be roughly divided into three parts:
One circuit fault; two is the oil circuit fault; three is the driving system failure, such as steering, braking, transmission parts, 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. Quiet down to the heart, analysis of the phenomenon of failure, 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. Two is the "test fire", if there is no central high pressure fire, sub cylinder fire, it is a circuit failure, such as high pressure fire, the problem is in the oil circuit. And mechanical failure is mostly accompanied by abnormal sound, sound with the speed of the speed and change, stop the sound disappeared, and the oil circuit is not directly related to the fault.
With "by paragraph of the negative law", "focus" locked in a specific place, first figure out what kind of fault is the first to see whether the external anomaly. If the wire is not open, short circuit, there is no loose connection parts; engine, there is no wire burning smell, oil pipeline has no oil leakage, 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 program.
