汽車照明系統常見故障有哪些

1、前照燈不亮

（1）故障現(xian)象：接通車(che)燈(deng)開關至(zhi)2或3擋時(shi)，小燈(deng)和(he)儀(yi)表(biao)正常，大燈(deng)遠近光燈(deng)均(jun)不(bu)亮。

（2）故障原因：引起燈光不(bu)亮的主(zhu)要原因有燈泡損(sun)壞、熔(rong)斷器熔(rong)斷、燈光開關(guan)或(huo)繼電器損(sun)壞及線(xian)路斷路或(huo)短路等。

（3）故障診斷：將車燈開(kai)關(guan)(guan)(guan)接(jie)(jie)至前照燈(deng)擋位，用(yong)試燈(deng)檢(jian)查(cha)變(bian)光(guang)(guang)開(kai)關(guan)(guan)(guan)的(de)“火線(xian)(xian)”接(jie)(jie)柱(zhu)。若試燈(deng)不亮(liang)，用(yong)試燈(deng)檢(jian)查(cha)車燈(deng)開(kai)關(guan)(guan)(guan)相應接(jie)(jie)柱(zhu)；若試燈(deng)亮(liang)，表明(ming)兩開(kai)關(guan)(guan)(guan)之間的(de)導(dao)線(xian)(xian)斷路；若試燈(deng)不亮(liang)，表明(ming)車燈(deng)開(kai)關(guan)(guan)(guan)損(sun)壞。檢(jian)查(cha)變(bian)光(guang)(guang)開(kai)關(guan)(guan)(guan)接(jie)(jie)線(xian)(xian)柱(zhu)時(shi)，若試燈(deng)亮(liang)，為變(bian)光(guang)(guang)開(kai)關(guan)(guan)(guan)損(sun)壞。用(yong)導(dao)線(xian)(xian)分(fen)別連(lian)接(jie)(jie)變(bian)光(guang)(guang)開(kai)關(guan)(guan)(guan)的(de)“火線(xian)(xian)”接(jie)(jie)柱(zhu)與遠、近光(guang)(guang)燈(deng)線(xian)(xian)接(jie)(jie)柱(zhu)，此時(shi)，遠近燈(deng)均應點(dian)亮(liang)。

2、遠光燈不亮

（1）故障現象：打開前照燈變(bian)光時，只有遠光或只有近光。

（3）故(gu)障(zhang)診斷(duan)：先將車燈(deng)(deng)開關(guan)(guan)接(jie)(jie)至(zhi)(zhi)前照燈(deng)(deng)擋(dang)，接(jie)(jie)通變(bian)(bian)光(guang)(guang)(guang)開關(guan)(guan)，察看遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)指(zhi)示(shi)燈(deng)(deng)。若(ruo)指(zhi)示(shi)燈(deng)(deng)亮，表明遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)燈(deng)(deng)線(xian)(xian)(xian)(xian)(xian)接(jie)(jie)點至(zhi)(zhi)線(xian)(xian)(xian)(xian)(xian)束導(dao)線(xian)(xian)(xian)(xian)(xian)斷(duan)路，或者兩(liang)遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)燈(deng)(deng)絲(si)燒壞(huai)。可(ke)在左(zuo)或右(you)接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)板(ban)遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)燈(deng)(deng)接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)柱上(shang)用試燈(deng)(deng)檢(jian)查：試燈(deng)(deng)亮，為兩(liang)遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)燈(deng)(deng)絲(si)燒壞(huai)；試燈(deng)(deng)不(bu)亮，為遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)指(zhi)示(shi)燈(deng)(deng)線(xian)(xian)(xian)(xian)(xian)至(zhi)(zhi)線(xian)(xian)(xian)(xian)(xian)束導(dao)線(xian)(xian)(xian)(xian)(xian)斷(duan)路。若(ruo)指(zhi)示(shi)燈(deng)(deng)不(bu)亮，為可(ke)靠起見(jian)，先檢(jian)查遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)指(zhi)示(shi)燈(deng)(deng)技術狀況(kuang)。若(ruo)良好，連(lian)接(jie)(jie)變(bian)(bian)光(guang)(guang)(guang)燈(deng)(deng)的“火線(xian)(xian)(xian)(xian)(xian)”接(jie)(jie)柱和遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)線(xian)(xian)(xian)(xian)(xian)接(jie)(jie)柱，觀察大(da)燈(deng)(deng)及(ji)遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)指(zhi)示(shi)燈(deng)(deng)：亮，表明變(bian)(bian)光(guang)(guang)(guang)開關(guan)(guan)損壞(huai)；仍不(bu)亮，表明遠(yuan)(yuan)(yuan)光(guang)(guang)(guang)指(zhi)示(shi)燈(deng)(deng)線(xian)(xian)(xian)(xian)(xian)結點至(zhi)(zhi)變(bian)(bian)光(guang)(guang)(guang)開關(guan)(guan)之間導(dao)線(xian)(xian)(xian)(xian)(xian)斷(duan)路。

3、近光燈不亮

（1）故障現象：近光燈(deng)不(bu)亮

（2）故障原因：變光器(qi)損壞、線路(lu)斷路(lu)或短(duan)路(lu)、燈絲燒斷、燈座接觸不(bu)良。

（3）故(gu)障診斷(duan)：將車燈(deng)(deng)(deng)開(kai)關(guan)打開(kai)，連接變(bian)光(guang)燈(deng)(deng)(deng)開(kai)關(guan)的“火線(xian)(xian)(xian)”接柱(zhu)和近(jin)光(guang)燈(deng)(deng)(deng)線(xian)(xian)(xian)接柱(zhu)，觀察大燈(deng)(deng)(deng)：亮，為(wei)(wei)變(bian)光(guang)開(kai)關(guan)損(sun)壞；仍不亮，為(wei)(wei)變(bian)光(guang)開(kai)關(guan)至線(xian)(xian)(xian)束(shu)導線(xian)(xian)(xian)斷(duan)路或(huo)兩近(jin)光(guang)燈(deng)(deng)(deng)絲(si)燒壞。可在(zai)左或(huo)右接線(xian)(xian)(xian)板近(jin)光(guang)燈(deng)(deng)(deng)接線(xian)(xian)(xian)柱(zhu)上用試燈(deng)(deng)(deng)檢查：試燈(deng)(deng)(deng)亮，為(wei)(wei)近(jin)光(guang)燈(deng)(deng)(deng)絲(si)燒壞；試燈(deng)(deng)(deng)不亮，為(wei)(wei)變(bian)光(guang)開(kai)關(guan)至線(xian)(xian)(xian)束(shu)導線(xian)(xian)(xian)斷(duan)路。

4、小燈、尾(wei)燈和儀表(biao)燈均不亮

（1）故障現象：燈光開關接至1檔時(shi)，小燈(deng)、尾燈(deng)和儀表燈(deng)均不(bu)亮。

（2）故障原因：燈光開關損壞、線路斷路、熔斷器熔斷、插接器松脫、燈炮燈絲斷。

（3）故障診斷(duan)(duan)：首先檢查(cha)熔(rong)(rong)電(dian)器是否(fou)(fou)損(sun)壞(huai)。若(ruo)(ruo)損(sun)壞(huai)，更換熔(rong)(rong)斷(duan)(duan)器后(hou)開燈(deng)檢查(cha)熔(rong)(rong)斷(duan)(duan)器是否(fou)(fou)再(zai)(zai)次熔(rong)(rong)斷(duan)(duan)。若(ruo)(ruo)再(zai)(zai)次熔(rong)(rong)斷(duan)(duan)，可(ke)能是線路或開關(guan)有短路故障，可(ke)采用斷(duan)(duan)路檢查(cha)法進行檢查(cha)。若(ruo)(ruo)正常(chang)(chang)，可(ke)檢查(cha)燈(deng)光開關(guan)相(xiang)應的(de)接柱上的(de)電(dian)壓是否(fou)(fou)正常(chang)(chang)。若(ruo)(ruo)電(dian)壓不正常(chang)(chang)，則(ze)(ze)可(ke)能是燈(deng)光開關(guan)相(xiang)應的(de)檔位損(sun)壞(huai)。若(ruo)(ruo)電(dian)壓正常(chang)(chang)，則(ze)(ze)應檢查(cha)相(xiang)應的(de)燈(deng)泡是否(fou)(fou)損(sun)壞(huai)。
