Pozdrav!
Kakav snijeg?!
Kod mene konacno doslo sunceeeeeeeee... tako da sam malo zakasnio sa reply-em. Poslao sam vam svima na e-mail a evo kacim i ovde. Sve je u pdf, na engleskom ali evo i nesto ukratko!
Nakon sto utvrdite koji tip ECU-a ima vas auto, potrebno je da nadjete konektor sa pinovima koji sluze za iscitavanje gresaka. Kod mog kadetta je GM-Multec Mpi sistem, a konektor se nalazi ispod haube na lijevoj strani, plavo crna plasika. Otvorite konektor i spojite pinove A i B. Za tacan raspored pinova kod vaseg auta pogledajte pdf u attachmentu. Kljuc u bravu , kontakt i pratite malu zutu lampicu koja simbolise "elektroniku". Kod mene je zuta :)
Sada je potrebno da pratite paljenje lampice i prema tome da ocitate koje greske je snimio ECU. Kratki treptaj je 1 , ugasena lampica oko sekund je pauza. dva treptaja za redom su 2, ..., 9 treptaja je 9, 10 treptaja je nula. Ovako ocitate prvu gresku. Signal za jednu istu gresku se ponovi 3 puta, nakon cega se prelazi na sledecu gresku (ako je ima). Posle ocitavanja svih gresaka , sve ide ponovo- u krug.
"Greska" 12 ce vam se uvijek prva pojaviti, jer je to signal same dijagnostike. Ako npr. ECU pokazuje samo gresku 13 dijagnostika je sledeca (* treptaj lapice, _ pauza)

itd... sve iz pocetka! Pogledate gresku (greske) u tabeli i to je to. Preporucujem da resetujete ECU prije dijagnostike. Skinete + klemu sa akumulatora na par sec. (RESET ECU), upalite auto da ECU snimi greske i onda radite ocitavanje istih.
Eto, nadam se da sam nekome pomogao. Ako nesto nije jasno, pitajte! :)
P.S. Cuvajte se crne greske 55. Brrrrrrrrrrr...... :(
