1️⃣ Umuyoboro wangiritse hamwe nubushyuhe bwubushyuhe
Impamvu isesengura: Ikimenyetso cyumuvuduko wo gufata ntigisanzwe, kandi ECU ntishobora kwakira amakuru yukuri yo gufata, bikavamo inshinge zidasanzwe.Gutwika ntibihagije, moteri iratinda, kandi umwotsi wumukara usohoka mugihe cya lisansi.Ibibazo hamwe na wiring harness ihuza hamwe no kunanirwa kwa sensor birashobora gutera kunanirwa.
Igisubizo: Reba umuyaga ufata hamwe nubushyuhe bwubushyuhe.
2️⃣ Kwangirika kwubushyuhe bwamazi
Impamvu isesengura.ECU igabanya umuvuduko wa moteri hagamijwe kurinda moteri.
Igisubizo: reba ubushyuhe bwamazi.

Impamvu isesengura.
Igisubizo: reba ibyuma byerekana amavuta.
4️⃣ Guhuza nabi kwa OBD sock terminal
Impamvu isesengura: OBD sock terminal isohoka, bivamo guhura nabi, nibikoresho byo gusuzuma na ECU ntibishobora kuvugana.
Igisubizo: reba OBD sock terminal.
5️⃣ Azote na ogisijeni sensor wire ibikoresho bigufi
Impamvu isesengura: ibikoresho bya azote na ogisijeni byambarwa, bikwirakwizwa bigufi kandi bigahagarara, kandi sensor ya azote na ogisijeni ntishobora gukora bisanzwe, bikavamo imyuka irenze urugero, moteri ya moteri ntarengwa hamwe na sisitemu yo gutabaza.
Igisubizo: reba insinga ya azote na sensor ya ogisijeni.
6️⃣ Kohereza imiti yo gushyushya ibyangiritse
Impamvu isesengura: Gukoresha amakosa yumuzunguruko.
Igisubizo: kugenzura no gusana ibikoresho byo gushyushya agasanduku.
7️⃣ Porogaramu yo hepfo yigikoresho iribeshya kandi ntabwo yohereza ibimenyetso byihuta byimodoka
