Keyword: Steam is repaired

The high speed development of auto industry raised taller requirement to our maintenance technician, more challenges. The maintenance technology that should have adroitness as a qualification, outstanding maintenance technician, can apply adroitly all sorts ofDiagnoseThe instrument reachs the capacity that integration analysis judges. Answer to raise oneself professional knowledge level ceaselessly at the same time, should learn professional knowledge ceaselessly, improve oneself integrated quality, just meet in real work handy. And eliminatingBreakdownWhen, correct and quick movement can achieve the result of get twice the result with half the effort with all sorts of methods.

One, it is difficult to conform to the principle of simplicity

Leave when a car into maintenance factory, we can understand the trouble that removes to need from inside maintenance. For example: EngineBreakdown light is bright, Idle fastFlabby, risk black smoke, cheer faint, Automatic transmissionDo not rise block reach block skid etc. We can be chosen among them simpler proceed with will solve, after this problem is solved, other issue also is met be readily solved.

Exemple: Dragon of a nimble (4 crocks of engine) car, engine trouble light is bright, risk black smoke, easyFlameout, flameout hind is difficult start, odograph needle chaos is placed.

Because this car key takes engineMalfunction code, simpler, and have specific aim, we are breach with this. Tone takes engine malfunction code: 1)Solar term doorThe positionSensorBreakdown. 2)Water is warmSensor breakdown. 3) advocate computer breakdown.
We check sensor of position of solar term door first, unplug sensor outlet, measure solar term door with avometer open degree of change to be worth, accord with standard numerical value, and appear without fluctuant value, show barrier of this sensor without reason. Will measure sensor again the wiring harness to computer, discover resistance is greater. Clear then circuit, chase paragraph pare total wiring harness, all the time to engine room left rear total outlet is in, discover this wiring harness has tatty mark, tear open the total thread of next this lines, discovery wears away few points, a few lines already were ground. Clear this wiring harness, assemble a car, cleared malfunction code, test-drive, afore-mentioned breakdown disappear.

Because this car is in other repair a factory to had been maintained, but the effect is not ideal, we use accurate method, ground of fast, accurate, economy solves a problem.

2, separation process

This method is a component (be like A) , control or protection are other component of a few jobs (be like B, C, D) . When among them a job (be like B) after occurrence breakdown, can affect control (A) , bring about other job (C or D) cannot work normally. Should control (A) when occurrence breakdown, we do not know the work (B, C, D) in which occurrence breakdown. Let first among them a job (B) do not work, if control (A) with other job (C, D) regular job, show this work (B) attaint.
