Pa-Board Diagnostic

OBD ndiye chidule cha On-Board Diagnostic m'Chingerezi, ndipo kumasulira kwachi China ndi "On-Board Diagnostic System". ndipo adzapereka chenjezo nthawi yomweyo ngati vuto lililonse lomwe lingayambitse kutulutsa mpweya wambiri litapezeka.Dongosolo likawonongeka, kuwala kosagwira ntchito (MIL) kapena chenjezo la injini (Check Engine) kuyatsa, ndipo dongosolo la OBD lidzasunga zolakwikazo kukumbukira, ndipo chidziwitso choyenera chikhoza kuwerengedwa ngati cholakwika. ma code kudzera mu zida zoyezetsa matenda komanso njira zowunikira.Malinga ndi kufulumira kwa code yolakwika, ogwira ntchito yosamalira amatha kudziwa mwamsanga komanso molondola mtundu ndi malo a cholakwikacho.

Makhalidwe a OBDII:

1. Maonekedwe a mpando wa matenda a galimoto yogwirizana ndi 16PIN.

2. Ili ndi ntchito yotumiza deta yosanthula nambala (DATA LINK CONNECTOR, yotchedwa DLC).

3. Gwirizanitsani zolakwika zomwezo ndi matanthauzo amtundu uliwonse wagalimoto.

4. Ndi ntchito yojambulira chojambulira.

5. Ili ndi ntchito yowonetseranso zolakwika za kukumbukira.

6. Lili ndi ntchito yochotseratu code yolakwika mwachindunji ndi chida.

Zipangizo za OBD zimayang'anira machitidwe ndi zigawo zambiri, kuphatikizapo injini, otembenuza catalytic, misampha ya tinthu tating'onoting'ono, masensa a okosijeni, machitidwe oyendetsa mpweya, machitidwe a mafuta, EGR, ndi zina.OBD imagwirizanitsidwa ndi unit control unit (ECU) kudzera muzinthu zosiyanasiyana zokhudzana ndi mpweya. , ndipo ECU ili ndi ntchito yofufuza ndi kusanthula zolakwika zokhudzana ndi umuna.Kulephera kwa umuna kumachitika, ECU imalemba zidziwitso zolephereka ndi ma code okhudzana, ndikupereka chenjezo kudzera mukulephera kudziwitsa woyendetsa.ECU imatsimikizira kupezeka ndi kukonza zidziwitso zolakwika kudzera mu mawonekedwe wamba a data.
