1996 855 cant read obd ?

[misha]

It has T (96)


But we found that it was 2.5 10v for Canada but now its 2.0t for italian market....

Not 2.0T...it's 2.0 T5R with 240hp.
If somebody don't know...2.0 T5R is introduced for Italian market ONLY because of high taxes which Italy have for engines above 2 liter.Just like Serbia and Greece.

@ bmdubya1198 ...pretty confusing,but 10v cars were a little late for obdII system and they use Siemens & Fenix ecu instead of Bosch.

Thanks to precopster's pointer and my special Vin decoder we figured it out.

...But what about my ECU ? What are those numbers? Is it ok?

VOLVO 850 20T B5204T 1275104 USA 155KW M43 CHK:A756 BOSCH 0261200548 1267358638
Yep...it's Motronic 4.3.
It have 210hp(155hp) stock.

Mine is 211hp stock but tuned to 240hp Its not originaly 240hp


And now i know i have m4.3....so, what should i do about diagnostics?

[misha]

Nothing....
It's more complicated than it seems because you don't know what wiring was actually transferred from a donor when engine & ecu(engine management)was replaced.
Could be something simple but could be also a nightmare.

I forgot to reply, i found the problem..... It was stupid led button which was somehow hard to press and now is ok, also cleaned the holes for a code cable and everything works perfect.
