安全氣囊故障燈亮的情況:
Air bag fault lights:
1、發(fā)動(dòng)機(jī)自檢
1. Self inspection of engine
著車的時(shí)候指示燈會(huì)亮,但自檢結(jié)束就會(huì)滅掉,大概5秒鐘,這個(gè)是正,F(xiàn)象,如果一直不滅說(shuō)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?qū)е職饽覠袅,比如如果電瓶虧點(diǎn)嚴(yán)重,氣囊就會(huì)回饋某個(gè)氣囊電壓低的信號(hào),產(chǎn)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(dòng)、線路斷路等,需要及時(shí)用診斷儀讀取故障代碼根據(jù)故障代碼找到故障點(diǎn)并排除解決。歷史故障達(dá)到ECU(氣囊系統(tǒng)控制單元)容錯(cuò)極限。用診斷儀**故障代碼,重新打車如果燈繼續(xù)亮說(shuō)明還是有當(dāng)前故障存在著,請(qǐng)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(dǎo)致外部電流進(jìn)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(diǎn)火開關(guān)的時(shí)候點(diǎn)亮6秒左右后熄滅,這是正常現(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(dòng)后或者使用車輛的時(shí)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(lái)進(jìn)行維修,在SRS燈亮起的時(shí)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.
