當汽車電腦故障時，偵測故障碼是診斷問題的第一步。 php小編魚仔將為您介紹幾種常見的汽車故障碼檢測方法，包括透過儀錶板、OBD介面或專業診斷工具。透過了解這些方法，您可以快速識別故障並採取適當措施，從而讓您的汽車盡快恢復正常運作。
一、汽車電腦故障碼怎麼檢測？
汽車故障電腦偵測器使用方法如下：
1、選好適合的故障偵測接頭，把接頭先接上解碼器連接線。
2、然後將接頭接到汽車的故障診斷座上，再用解碼器的工作電源線接到點煙器上（診斷座自帶電源的可免此項）。
3、車輛點火開關轉至ON，這時螢幕顯示出選單，我們這時可根據需要檢查的項目來選擇特定的子選單。
4、選擇後可能過解碼器上的螢幕讀到故障部位的名稱，有多個故障的則同時在螢幕上顯示出來。
5、注意故障的名稱只是代表它所在的這一部分的電路，並不一定就是這個零件。
6、清除故障碼：前面的程式和提取故障碼一樣，只是在選擇子選單時選擇清除故障碼，透過對話框的問答選擇清除。
二、汽車電腦故障能消除嗎？
有診斷儀的話進入診斷儀的操作畫面就可以清除，這個過程就像玩電腦卸載軟體那麼簡單。
沒有診斷儀的話只能拆下蓄電池負極5分鐘以上，等電腦板的電容器沒電了，記憶體中的故障碼就自動丟失，從而清除故障碼。
關閉點火開關並不能清除故障碼，因為電腦板的電源不受點火開關控制，關閉點火開關電池還是能為電腦板供電的，只要電腦板中的電容器還有電，電腦板記憶體中就會一直儲存該故障碼。

5. Will it be normal if the car computer fault code is eliminated?
The fault code can be eliminated, but it does not mean that there is no problem.
There are generally two types of faults, one is current fault and the other is accidental fault. There is currently a fault and the fault code cannot be cleared. Occasional faults can be eliminated, but the fault code will reappear when the vehicle is driven under certain conditions. If the unexpected fault code is caused by irregular maintenance or driving, and the vehicle is not faulty, it can be deleted directly. The sensor is not working well and is judged as a fault by the ECU. The fault code left behind is not a real fault.
