Is there any way to check faults on an early (V plate) Sei? Checked for OBD port but there's none. Is there a diagnostic port that can be bridged with a paperclip or something?

Yeah the ecu's can be read, the mk1 sei's have a different diagnostic port in the engine bay close to the ecu, it's a little plug compared with the mk2 sei's having the bigger rectangle obd port inside the car similar to other modern cars.

It can be read with those skyes pickavant handheld machines too with the proper cable and pod,
but the method below is much more cost effective.

This is a useful link,with the info provided by ming,it's a good read worth checking out

Interesting, I don't have a windows laptop though, running linux, I have a reader in the post though. Any idea what protocol it is?

I suppose this trick should work then http://www.puntosports.co.uk/forums/showthread.php?31927-Blink-Test-Codes&highlight=blink test I'll give it a shot.

V plate Sei is a Cinq in drag so use a multimeter and the nominals list to fault find.

Cheers

agreed, had many cinqs and spi sei's and never had a need to get a reader or anything, the engines are simple enough to not need one.. You only really need a wire and laptop and stuff if you want to log data on these really.

Whats your problem, why do you want to read the codes? Have you got the engine management light on or something?

The problem is here https://www.fiatforum.com/cinquecento-seicento/321939-emissions-mot-fail.html the garage suggested diagnostics to find out what caused the emissions problems.

ah right yeah, well i replied on the other thread...

I am intrigued however if a blink test would work on a cento, not something i ever thought of. I still don't think its really required but i am curious to know if it would work - anyone ever tried?

I tried, and it didn't work.

lol, fair enough

where do you live I've got a cable

I looked it up in the Haynes manual

Automotive Diagnostic Fault codes manual #3472

and it says the ECU does not do flashes i.e. needs a reader...

Cheers for the offer, but I've got one now, can't get that program to work though. No worries, think I've found the fault anyway.
