diagnostika

Na 7xx/9xx (850) do 95 godista diagnostika se moze vrlo lako uraditi bez majstora i raznoraznih diagnostickih uredjaja. Ovi modeli imaju sopstveni diagnosticki uredjaj koj se nalazi na prednjem levom(vozacevom) kosu/muldi. Skine se poklopac uredjaja i oslobodi kablic sa okruglom buksnom koj se kasnije bode u odredjena mesta u zavisnosti od toga sta se zeli kontrolisati.
A1-automatski menjac
A2-sistem ubrizgavanja goriva
A3-ABS
A5-turbo TCU/CEM
A6-sistem paljenja
A7-instrumenti
Neki modeli imaju jos jednu diagnosticku jedinicu i u tom slucaju je:
B1-klima(850)
B2-tempomat
B5-vazdusni jastuci
B6-sedista
Stavi se kljuc u kontakt bravi u polozaj II. Zatim se kablic ubode u odredjen broj u zavisnosti od toga sta se zeli kontrolisati. Stisne se taster na diagnostici i zadrzi izmedju 1 i 3 sekunde. Nakon otpustanja tastera dioda ce poceti da blinka u trocifrenim intervalima. Svaki kod se sastoji iz tri cifre. 111 je znak da je sve ok i td... Kodovi se lako mogu naci na internetu pa o njima necu sad pisati. Postupak se ponavlja sve dok se pojavljuju nove greske. Brisanje gresaka se obavlja tako sto se tastar stisne i zadrzi duze od 5 sekundi. Nakon otpustana se saceka da se dioda upali pa jos jednom stisne i zadrzi takodje duze od 5 sekundi. Greske se uvek mogu obrisati i skidanjem kleme sa akumulatora. Greske su uspesno obrisane ako sledeci kod bude 111.

A evo ideje ako nekom treba OBD2 diagnostika za 9xx 96+ god (a moze da posluzi i za 850).
Potrebno je nesto malo zica i dzekovi OBD A i B sa 7xx/9xx 96- god i 16 pinski muski konektor OBD2.
Raspored vezivanja:
OBD2 pin1-----OBD A6 paljenje
OBD2 pin3-----OBD A2 ubrizgavanje
OBD2 pin4,5---OBD A8 masa
OBD2 pin6-----OBD B1 klima ECC 850
OBD2 pin7-----OBD A7 instrumenti + kombinovano 850
OBD2 pin12----OBD A3 ABS
OBD2 pin13----OBD B2 tempomat
OBD2 pin16----OBD A4 +12V
Lako i jeftino se napravi, prosto za koriscenje a moze puno da pomogne...

Moze se to jednostavnije napraviti sa LED diodom i tasterom

Moze se to jednostavnije napraviti sa LED diodom i tasterom

Moze i jos jednostavnije ako bas to zelis cak i bez tastera. Samo 3 zice sa iglama i diodom.
Al je malo neugledno kad nekom sa tim citas greske jbg...

Dižem temu jer mi treba.
