Atitinkamai trumpinami kontaktai:
A ir B variklio valdymo sistemos diagnistikai (skydelyje dega geltonas indikatorius su variklio sablonu)
A ir K stabdziu antiblokavimo sistemos ABS diagnostikai
A ir J 4 varomu ratu sistemos (4x4) diagnostikai
A ir J (taip pat su 4x4) TC kontrole (nevisuose automobiliuose yra sitie kontaktai)
A ir C automatines greiciu dezes (AT) diagnostikai
A ir H gamyklines sergejimo sistemos (siganlizacijos) diagnostikai
Kodai nuskaitomi skaiciuojant atitinkamos lemputes sumirksejimu skaiciu. Kiekvienas kodas susideda is dvieju skaitmenu. skaitmenys isduodami su pauze tarp mirktelejimu 0,5s, tarpai tarp skaitmenu - 1s. Kiekvienas kodas kartojams 3 kartus.
Atliekant visu sistemu diagnostika, pirmas parodomas 12 kodas, reiskiantis, kad sistema ijungta i diagnostikos rezima. Tai ne gedimas! Jeigu 12 kodas kartojamas pastoviai - gedimu nera.

Taip pat, visu sistemu klaidu kodai gali buti nuskaiti naudojant 'TECH 1' diagnostine iranga.
Klaidu trynimas:
iprastai klaidos issitrina 20 kartu ijungus degima, jeigu klaida daugiau nepasikartoja arba atjungus akumuliatoriu 60s.. Naujesniuose Calibra modeliuose klaidas istrinti galima tik naudojant spec iranga -'TECH 1"
