2、故(gu)障(zhang)分類電子汽車衡(heng)發生(sheng)的(de)故(gu)障(zhang)多(duo)種多(duo)樣(yang)，對故(gu)障(zhang)的(de)判斷可以按照先機(ji)械再(zai)電子，由(you)外向內(nei)，由(you)易轉難的(de)順序進行排(pai)除(chu)和(he)診(zhen)斷。*機(ji)械故(gu)障(zhang) 秤(cheng)(cheng)(cheng)體(ti)(ti)用久變形、限(xian)位裝置頂死(si)秤(cheng)(cheng)(cheng)體(ti)(ti)、秤(cheng)(cheng)(cheng)體(ti)(ti)移位、秤(cheng)(cheng)(cheng)體(ti)(ti)底(di)部(bu)及其(qi)與(yu)護邊框(kuang)縫隙之(zhi)間(jian)有異物卡住、連(lian)(lian)接件斷裂（剪切梁式傳感器(qi)）、秤(cheng)(cheng)(cheng)體(ti)(ti)水平度破壞、多(duo)段秤(cheng)(cheng)(cheng)體(ti)(ti)之(zhi)間(jian)連(lian)(lian)接松動、傳感器(qi)移位和(he)基(ji)礎下沉等。

電(dian)子(zi)故(gu)障儀表、傳感器(qi)、接線(xian)盒(he)（接線(xian)電(dian)路板(ban)）故(gu)障，總信號電(dian)纜(lan)的接插件松動、焊點虛焊或脫落(luo)、信號電(dian)纜(lan)折斷(duan)和(he)絕緣性能下降等。
