(4)若無故障碼,對(duì)有明顯故障征兆的,可用診斷儀、示波器、萬用表等讀取有關(guān)發(fā)動(dòng)機(jī)數(shù)據(jù),進(jìn)行數(shù)值、波形分析;并依據(jù)分析結(jié)果,檢查有關(guān)部件,視需要進(jìn)行維修或更換。若無明顯故障征兆,則采用癥狀模擬方法對(duì)故障進(jìn)行分析,以進(jìn)一步檢查故障的原因。

(4) if there is no trouble code, the obvious signs of failure, the available diagnostic instrument, oscilloscope, million meters read about the engine data, numerical, waveform analysis; and according to the analysis results, check the relevant components, depending on the need for repair or replacement. If there is no obvious fault symptom, the symptom of the fault analysis method, to further check the fault.

(5)若有故障碼,則根據(jù)故障碼的內(nèi)容檢查并排除故障。

(5) if fault code, according to the contents of the fault code check and troubleshooting.

(6)重新起動(dòng)發(fā)動(dòng)機(jī),驗(yàn)證故障是否已排除。若故障未排除,則繼續(xù)檢查故障原因。

(6) to start the engine, to verify whether the fault has been ruled out. If the fault is not excluded, then continue to check the cause of the problem.
