安全氣囊故障燈亮的情況:
Air bag fault lights:
1、發(fā)動機自檢
1. Self inspection of engine
著車的時候指示燈會亮,但自檢結束就會滅掉,大概5秒鐘,這個是正,F(xiàn)象,如果一直不滅說明有故障。
When the car is on, the indicator light will be lit, but the self inspection will be destroyed. It will be 5 seconds. This is a normal phenomenon. If it is kept clear, it will be defective.
2、假故障。
2, false fault.
畢竟氣囊是線路控制,有很多原因導致氣囊燈亮,比如如果電瓶虧點嚴重,氣囊就會回饋某個氣囊電壓低的信號,產生故障碼 ,這種情況**即可。
After all, the air bag is line control, and there are many reasons to cause the airbag light to be bright. For example, if the battery is badly damaged, the air bag will feed back a signal with a low voltage of the air bag to produce a fault code, which can be removed.
3、真發(fā)生故障
3. A real fault
所涉及的故障原因較多,比如安全氣囊故障、氣囊游絲故障、碰撞傳感器故障、氣囊插頭松動、線路斷路等,需要及時用診斷儀讀取故障代碼根據故障代碼找到故障點并排除解決。歷史故障達到ECU(氣囊系統(tǒng)控制單元)容錯極限。用診斷儀**故障代碼,重新打車如果燈繼續(xù)亮說明還是有當前故障存在著,請參照“1”的步驟排除。
There are many reasons for the failure, such as air bag fault, air bag lotion fault, collision sensor fault, air bag plug loosening, circuit breakage and so on. It needs to read fault code in time to find fault points according to the fault code and eliminate the solution. Historical failures reach the ECU (airbag system control unit) fault tolerance limit. Use the diagnostic instrument to remove the fault code, and then re take the taxi. If the lamp continues to light, there is still the current fault. Please refer to the steps of 1 to exclude.
讀取故障碼 如果有短路接地的故障 有可能導致外部電流進去氣囊回路,有誤爆的可能。
If the fault code is read, if there is a short circuit grounding fault, it may lead to an external current entering the airbag loop, and there may be a false explosion.
打開點火開關的時候點亮6秒左右后熄滅,這是正,F(xiàn)象
Turn on the ignition switch and turn it off for about 6 seconds. This is a normal phenomenon.
如果在在啟動后或者使用車輛的時候亮起不熄滅證明安全氣囊系統(tǒng)有故障
If it does not extinguish after startup or when the vehicle is used, it proves that the airbag system is faulty.
需要用診斷電腦提取故障代碼來進行維修,在SRS燈亮起的時候,安全氣囊系統(tǒng)停止功能,
It is necessary to use the diagnostic computer to extract fault codes for maintenance. When the SRS lights are on, the airbag system stops functioning.
