Technical Fiat Uno 1.0ie 1997 OBD 3 pin conection
Hi,

-Thanks ! Do you think if i buy the cable that converts 16 pin to 3 pin and Mini OBD ELM327 from ebay i will be able to detect a computer and temperature sensor problem ? Or if not please tell me what is by your opinion best way to do that. Thnaks in advance!

it should connect to a few things.. I've never used it on an uno - so cannot comment,
but the MES site should tell you what it can communicate with,
looks like you need a 3-pin adaptor cable , and a VAG_COM KKL Cable

Hi there
These first unos have a very basic electronic injection. This guide may help:
https://www.fiatforum.com/cinquecento-seicento-guides/238241-reading-spi-ecu-data-logging.html although I am not sure that software works for the Uno. I was looking for a post here on fiatforum where someone came up with a DIY code reader gizmo made up with a LED. The procedure was to bridge two of the three pins and the LED would flash a number of times depending on the error. Sadly couldn't find it.
However there's a troubleshooting post here: https://www.fiatforum.com/uno/27621-uno-999-fire-ie-erratic-idle-warm-up-bosch-spi.html and have a look at post #10 .
I think it may give you some better help than an ECU reader.
I hope this helps

good stuff Alfonso,
just to point out - that info is for the UK models of @1990 to 1995
I believe the SA Models ran a lot later..probably with different electronics, and injection.
