I-P0688 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga engu-P0688 iyikhodi yenkinga evamile ebonisa ukungasebenzi kahle kwe-Engine Control Module (ECM) noma i-Powertrain Control Module (PCM) yokulawula ukudluliswa kwamandla kwesekethi.

Isho ukuthini ikhodi yenkinga P0688?

Ikhodi yenkinga engu-P0688 ibonisa inkinga kumojula yokulawula injini (ECM) noma imojuli yokulawula i-powertrain (PCM) yokulawulwa kokudluliselwa kwamandla emotweni. Le khodi yenzeka lapho isekethe yokulawula ukudluliselwa kwamandla kwe-ECM/PCM inganikezi i-voltage evamile njengoba kucaciswe yizicaciso zomenzi.

I-ECM ne-PCM yizingxenye zemoto ezinomthwalo wemfanelo wokulawula injini nezinye izinhlelo zemoto. Athola amandla nge-relay evula noma evala amandla ebhethri. Ikhodi ye-P0688 ikhombisa ukuthi kunenkinga ngale sekhethi yamandla, engabangela injini noma ezinye izinhlelo zemoto ukuthi zingasebenzi kahle. Kubalulekile ukuqaphela ukuthi le khodi ngokuvamile ivela ezimotweni ezisebenzisa i-ECM/PCM power relay futhi ingase ingasebenzi kwezinye izinhlobo zezimoto noma amasistimu okuphatha injini.

Izizathu ezingenzeka

Izizathu ezingenzeka ze-DTC P0688:

• Izintambo ezilimele noma eziphukile: Izintambo ezixhuma ukudluliswa kwamandla ku-ECM/PCM noma kumphakeli kagesi zingase zonakaliswe, ziphuke, noma zishiswe, okuholela ekulahlekeni kokuthintana kukagesi namandla anganele.
• Ukuxhumana okungalungile noma i-oxidation yabathintwayo: Kuyadingeka ukuhlola isimo soxhumo kanye noxhumana nabo kumjikelezo wokulawula ukudluliselwa kwamandla. I-oxidation noma uxhumo olungeluhle lungaholela ekwehliseni ukuthintana kukagesi futhi kubangele ukutholakala kwamandla okwanele.
• Ukudluliselwa kwamandla okungalungile: Ukudluliselwa kwamandla ngokwawo kungase kungasebenzi, kubangele ukudluliswa kwamandla okwanele ku-ECM/PCM.
