說明
1. 本手冊僅針對國三柴油機電控方面的故障，機械方面的故障可以按照國二方法解決。
2. 國三系列柴油機采用電控系統(tǒng)，與采用機械泵時有本質(zhì)區(qū)別，需要采用專用的診斷工具。
3. 濰柴動力國三系列柴油機采用bosch 公司的第二代共軌系統(tǒng)。共軌系統(tǒng)對油路（包括低壓油路和高壓油路）要求較高，很多問題都是由油路問題引起的；其次，整車線束問題也是主要的故障源。
4. 閃碼是對ECU 錯誤內(nèi)部錯誤的一個初步判斷，更進一步的判斷要用診斷儀。
Blink code can be displayed in three levels of blinking.
閃碼以三位的形式顯示
1. First level of blinking will classify an error specific to part of an system, for e.g. if error is because of ECU, Hydraulics,Sensors,Actuatators
第一位將錯誤按系統(tǒng)分類，比如說一個錯誤是否是由ECU、液壓部件、傳感器、執(zhí)行器引起的；
2. Second Level of Blinking will indicate details about component identified.
第二位表明發(fā)生錯誤的部件；
3. Third Level will uniquely identify the Fault Path
第三位確定錯誤路徑。
