Youdaoplaceholder0 Matsalar fitar da hayaki: Baƙar hayaki yana fitowa daga bututun shaye-shaye yayin haɓakawa kwatsam, sau da yawa saboda ɗimbin arziƙi mai yawa wanda ke haifar da rashin aiki na firikwensin zafin jiki. "
Tsarin kulawa da aka ba da shawarar
Youdaoplaceholder0 Binciken farko: Yi amfani da multimeter don auna ko juriyar firikwensin ya dace da halayen ma'aunin zafi (kamar juriya yana raguwa yayin da zafin jiki ya tashi) don tantance ko akwai lalacewar jiki. "
Youdaoplaceholder0 Karatun lambar kuskure : Sami takamaiman lambobin kuskure (misali P003D) ta hanyar haɗin OBD don gano firikwensin ko matsalolin da'ira masu alaƙa.
Youdaoplaceholder0 Maye gurbin sashi: Idan firikwensin ya gaza, ana buƙatar maye gurbin ɓangaren samfurin iri ɗaya (lura da bambanci a cikin filogi tsakanin firikwensin 12V da 5V). "
Youdaoplaceholder0 Duba tsarin: Bincika dabarun sarrafa ECU da haɗin haɗin kai don hana ƙararrawar ƙarya saboda saƙon haɗi ko gajeriyar kewayawa. "
Idan akwai zafi fiye da kima ko raguwar wutar lantarki, ana ba da shawarar dakatar da abin hawa nan da nan kuma tuntuɓi ƙwararrun ma'aikatan kulawa don hana ƙarin lalacewa ga mahimman abubuwan kamar ECU ko thermistors.
"Idan kana son ƙarin sani, ci gaba da karanta sauran labaran kan wannan rukunin yanar gizon!
Da fatan za a kira mu idan kuna buƙatar irin waɗannan samfuran.
