Car OBD2 Communication Control Board

Galimoto OBD2 Communication Control Board Yokhala ndi Chithunzi

Kufotokozera Kwachidule:

Mwinamwake mwakumanapo kale ndi OBD2:

Kodi mwawonapo kuwala kowonetsa kusagwira ntchito pa dashboard yanu?

Ndi galimoto yanu ikukuuzani kuti pali vuto.Mukayendera makaniko, amagwiritsa ntchito sikani ya OBD2 kuti azindikire vutolo.

Kuti achite izi, alumikiza owerenga OBD2 ku cholumikizira cha pini cha OBD2 16 pafupi ndi chiwongolero.

Izi zimamupangitsa kuti awerenge ma code a OBD2 aka Diagnostic Trouble Codes (DTCs) kuti awonenso ndikuthetsa vutolo.

Cholumikizira cha OBD2

Cholumikizira cha OBD2 chimakupatsani mwayi wopeza data kuchokera mgalimoto yanu mosavuta.Muyezo wa SAE J1962 umatchula mitundu iwiri yolumikizira yachikazi ya OBD2 16 (A & B).

M'fanizoli pali chitsanzo cha cholumikizira pini cha Type A OBD2 (chomwe chimatchedwanso Data Link Connector, DLC).

Zinthu zingapo zoti muzindikire:

Cholumikizira cha OBD2 chili pafupi ndi chiwongolero chanu, koma chikhoza kubisika kuseri kwa zivundikiro / mapanelo

Pin 16 imapereka mphamvu ya batri (nthawi zambiri pomwe kuyatsa kuli kozimitsa)

Pinout ya OBD2 imadalira njira yolumikizirana

Ndondomeko yodziwika kwambiri ndi CAN (kudzera ISO 15765), kutanthauza kuti ma pin 6 (CAN-H) ndi 14 (CAN-L) nthawi zambiri amalumikizidwa.

Pazofufuza, OBD2, ndi 'protocol yapamwamba' (monga chilankhulo).CAN ndi njira yolumikizirana (monga foni).

Makamaka, muyezo wa OBD2 umatchula cholumikizira cha OBD2, kuphatikiza.seti ya ma protocol asanu omwe amatha kuyendetsa (onani pansipa).Kupitilira apo, kuyambira 2008, CAN bus (ISO 15765) yakhala protocol yovomerezeka ya OBD2 pamagalimoto onse ogulitsidwa ku US.

ISO 15765 imatanthawuza zoletsa zomwe zimagwiritsidwa ntchito ku muyezo wa CAN (womwe umafotokozedwa mu ISO 11898).Wina anganene kuti ISO 15765 ili ngati "CAN yamagalimoto".

Makamaka, ISO 15765-4 imalongosola mawonekedwe akuthupi, ulalo wa data ndi magawo a netiweki, kufunafuna kuyimitsa mawonekedwe a mabasi a CAN pazida zoyesera zakunja.ISO 15765-2 imafotokozanso zamtundu wa mayendedwe (ISO TP) potumiza mafelemu a CAN okhala ndi zolipira zomwe zimapitilira ma 8 byte.Mulingo wocheperawu nthawi zina umatchedwanso Diagnostic Communication over CAN (kapena DoCAN).Onaninso fanizo la 7 layer OSI model.

OBD2 itha kufananizidwanso ndi ma protocol ena apamwamba (mwachitsanzo J1939, CANopen).
