Zvinoumba OBDII:

1. Chimiro chechigaro chekuongorora chemotokari yakabatana ndeye 16PIN.

2. Iine basa rekutsvaga nhamba yekufambisa data (DATA LINK CONNECTOR, inonzi DLC).

3. Batanidza makodhi ezvikanganiso zvakafanana uye zvinoreva zverudzi rwemotokari yega yega.

4. Nekutyaira rekodhi basa.

5. Iine basa rekuratidza zvakare chiyeuchidzo chinokanganisa code.

6. Iine basa rekuchenesa kodhi yekodhi zvakananga nechiridzwa.

OBD zvishandiso zvinotarisisa masisitimu akawanda uye zvikamu, zvinosanganisira injini, catalytic converters, traiculate trap, oxygen sensors, emission control system, mafuta masisitimu, EGR, nezvimwe.OBD yakabatana neelectronic control unit (ECU) kuburikidza neyakasiyana-siyana-inoenderana nechikamu ruzivo. , uye ECU ine basa rekuona nekuongorora zvikanganiso zvine chekuita nekubuda.Kana kutadza kuburitsa kunoitika, ECU inorekodha ruzivo rwekukundikana uye makodhi ane hukama, uye inopa yambiro kuburikidza nemwenje yekutadza kuzivisa mutyairi.ECU inovimbisa kuwanikwa uye kugadziriswa kweruzivo rwekukanganisa kuburikidza neyakajairwa data interface.
