ABS燈亮一般(ban)意味著汽車的制動防抱死系統出(chu)現故障。

汽(qi)車(che)的(de)ABS系(xi)統(tong)(tong)能(neng)在(zai)緊急制(zhi)(zhi)動(dong)(dong)時(shi)防止車(che)輪(lun)抱死，確保行(xing)車(che)安(an)全。每(mei)次車(che)輛啟動(dong)(dong)，該系(xi)統(tong)(tong)會自(zi)動(dong)(dong)進行(xing)自(zi)檢(jian)(jian)，此時(shi)ABS燈(deng)(deng)短暫亮(liang)(liang)起(qi)，隨后熄(xi)滅，屬于正常(chang)現(xian)象。若ABS燈(deng)(deng)常(chang)亮(liang)(liang)，問題(ti)可(ke)能(neng)出在(zai)多個方(fang)面(mian)。輪(lun)速傳感器故(gu)障較為(wei)常(chang)見，它可(ke)能(neng)本身(shen)損壞，也(ye)可(ke)能(neng)因臟污影響檢(jian)(jian)測。臟了清潔即可(ke)，損壞則需(xu)更換。線(xian)(xian)路(lu)方(fang)面(mian)，如插(cha)線(xian)(xian)松動(dong)(dong)、線(xian)(xian)束與ABS泵間(jian)的(de)接(jie)頭(tou)問題(ti)等，都可(ke)能(neng)導(dao)致(zhi)故(gu)障，需(xu)檢(jian)(jian)查(cha)(cha)插(cha)頭(tou)、保險絲和搭(da)鐵(tie)線(xian)(xian)。制(zhi)(zhi)動(dong)(dong)液(ye)不足也(ye)會引發ABS燈(deng)(deng)亮(liang)(liang)，若與駐車(che)制(zhi)(zhi)動(dong)(dong)燈(deng)(deng)同時(shi)點亮(liang)(liang)，要檢(jian)(jian)查(cha)(cha)制(zhi)(zhi)動(dong)(dong)片與漏油情況。此外，防抱死制(zhi)(zhi)動(dong)(dong)系(xi)統(tong)(tong)傳感器污染信(xin)號面(mian)板(ban)、ABS線(xian)(xian)路(lu)連(lian)接(jie)問題(ti)、控制(zhi)(zhi)單元(yuan)故(gu)障、ABS總(zong)泵老化等，也(ye)都可(ke)能(neng)是罪魁禍(huo)首。

總(zong)之，ABS燈亮起不可掉以輕心，雖車(che)輛仍能正常駕駛，但急(ji)剎(cha)時(shi)存在抱死風(feng)險(xian)。發現(xian)ABS燈常亮，應盡快前往維修(xiu)店(dian)進行檢修(xiu)，以保(bao)障行車(che)安全。
