汽(qi)車(che)的(de)ACC線(xian)通常在汽(qi)車(che)的(de)保險絲盒里，可(ke)通過多種方法找(zhao)到 。

汽(qi)車(che)一(yi)(yi)(yi)般有兩(liang)個(ge)保(bao)(bao)險(xian)(xian)(xian)(xian)絲盒，一(yi)(yi)(yi)個(ge)在發動(dong)機艙右側(ce)，另一(yi)(yi)(yi)個(ge)在轉向柱下部(bu)(bu)左側(ce)。ACC線是自適(shi)應巡航控(kong)制系(xi)統的電(dian)(dian)(dian)(dian)源線，由車(che)鑰匙(chi)控(kong)制，為車(che)載音響等設備供電(dian)(dian)(dian)(dian)。首(shou)先可關閉全車(che)電(dian)(dian)(dian)(dian)源，讓(rang)儀表盤(pan)熄滅，打開(kai)汽(qi)車(che)保(bao)(bao)險(xian)(xian)(xian)(xian)絲盒（大部(bu)(bu)分位于(yu)主駕駛門和中(zhong)控(kong)臺的交界(jie)處）。接著按下一(yi)(yi)(yi)鍵啟動(dong)按鈕（注意不要踩剎(cha)車(che)），車(che)輛進入ACC模(mo)式(shi)。也(ye)可以用試(shi)(shi)(shi)電(dian)(dian)(dian)(dian)筆測(ce)試(shi)(shi)(shi)，在保(bao)(bao)險(xian)(xian)(xian)(xian)盒內找到黃色小金屬保(bao)(bao)險(xian)(xian)(xian)(xian)絲，用試(shi)(shi)(shi)電(dian)(dian)(dian)(dian)筆觸碰頂部(bu)(bu)金屬點，全車(che)通(tong)電(dian)(dian)(dian)(dian)后若電(dian)(dian)(dian)(dian)筆上黃色保(bao)(bao)險(xian)(xian)(xian)(xian)絲亮燈(deng)，即為ACC線。還能(neng)使用萬用表測(ce)試(shi)(shi)(shi)每個(ge)保(bao)(bao)險(xian)(xian)(xian)(xian)絲；或者順(shun)著ACC開(kai)關一(yi)(yi)(yi)路查找，拿電(dian)(dian)(dian)(dian)筆一(yi)(yi)(yi)頭(tou)搭上鐵，帶尖的一(yi)(yi)(yi)頭(tou)扎方向盤(pan)下的點火線，打開(kai)轉向燈(deng)，扎到電(dian)(dian)(dian)(dian)筆上小燈(deng)跟著閃的線就(jiu)是ACC線 。

總之，只要按照上述方法(fa)，在汽車(che)保險絲盒處仔(zi)細操作(zuo)與判斷(duan)，就能(neng)順(shun)利找到汽車(che)的ACC線(xian)，為后續連(lian)接相關設(she)備或(huo)進行其他(ta)操作(zuo)提供便利。
