Hi All,

Do any of you know if this would work on my 1.2 SX 16V 2001 Bravo?:

http://cgi.ebay.co.uk/Diagnostic-Interface-Fault-Tool-for-Fiat-Punto-Bravo_W0QQitemZ300318590724QQcmdZViewItemQQptZUK_Diagnostic_Tools_Equipment?hash=item45ec620704&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1683%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50

I have a 16pin connector under the dash

I'm not sure what the ISO9141 & ISO14230 (KWP2000) Protocol is and if my car has it! I'm looking at getting fault codes and live engine data from my car. Any other cheapish suggestions?

Thanks!

It should work yes as the Bravo uses protocol ISO9141, not sure about the software it uses but the protocols is correct. Cheapest option is to make your own cable.
 
how u can make it, and what u need to read it? special reader or pc would do?
i would like to know aprox minimum price u can make 1 :)
 
where i can find that connector? i have looked but with no results..

well maybe stupid question, but would that work on my ´97 bravo 1.6 ?
have seen used w/o original connector, so connected with wires - noone else did it for fiat :(. so can, and how hard if i could...

It wont work as your car doesn't have the EODB port. You can make a 3 pin cable but again you'll need to build the cable.

I made my cable for around £20-£25 just parts, the software i have is free and works on my car perfectly and others supporting the same protocol. I am using an RS232 plug to ODBII for my cable. So to make it work all you need is a laptop. You can buy RS232 to USB convertors.
 
could u list all parts u made? would work with my car too then?
 
so u have 16bin connection? i havent found it from my bravo :( - if it has.
but shuld work? i would like to buy 1 for myself but for me local sellers sell it for ~200$ minimum :S. so no way i can test it.
so i need 1 that reads EOBD? not OBD2?
could u test it, maybe u can try it on some older bravo?

tnx

The Bravo/a and Mareas are not ODBII, they are EODB however they use the universal ODBII connector. Fiat started to fit EODB connectors to cars before the auto legislation changed to make it compulsory for ODB and ODBII all-in-one diagnostic ports to be fitted to new cars (2001 petrols 2004 diesels). You can say they were one of the first. :) The only down side is that they used there own protocols.

From 95-00

All petrol Bravo/a and Mareas upto 2000 (except the 1.2), have several 3 pin diagnostic connectors located on the car.

All diesel Bravo/a and Mareas upto 2000, have several 3 pin diagnostic connectors located on the car.

2001 onwards

The 1.2, 1.6 and 2.0 Fiat Bravo/a and Mareas from 2001 onwards, have a 16 pin EODB all-in-one diagnostic connector. (not sure about the 1.8, by law it should have but there is no reference to Fiat fitting it to any 1.8 Bravo).

All diesel Bravo/a and Mareas from 2001 onwards, have a 16 pin EODB all-in-one diagnostic connectors.

or not, any commenct would be appriciated

I've now ordered the one I originally asked about at the top of this thread. I'll see how it goes when it arrives and report back. As my car has the 16 pin connector and is a late model, I'm hoping it will work.

I did find some circuit diagrams for making a cable, but found the time it would take to make and the cost of components wasn't worth the time over a bought model.
 
You cant build the cable you have bought for a few quid anyway, as its an ELM interface and has a microcontroller in it. As its an ELM323, if it doesnt work out of the box you might be are stuck as you cant change many (if any) of the parameters (header info etc). You should be fine given the year of your car.

Doesnt matter - 16 pin or 3 pin. Same schematic will work for both, just a different plug on the end. All they do is level shift the +/- 12v used by the car to the levels a serial port can cope with, around +/- 5vdc

so could i use the one i noted be4 on my bravo 1.6 ´97?
 
I seriously doubt that would work on a '97 bravo, even with a 16pin to 3pin converter.

I know for a fact you can make your own cable that will work, the one 'Stroke' linked too is a 16pin to 3 pin convertor, therefore useless as you dont have a 16pin to convert. Wait until Syncro has tested the ELM interface then all you need to do is, buy the same device, get four wires and spade connectors and croc clip and make your own 3 wire convertor.

Stroke PM me and I will show you how to make a cable that will work and how to wire the above ELM interface to make a 3pin connector.

I haven connected anything to a bravo in years. I used to use my own software which was two little dos utilities (one for reading codes, one for clearing) - very very basic.

Building the actual cable is the easy part - as its just a level shifter - there are lots of designs about. The software is the difficult part, it depends on what ecu your car has - they dont all use the same communication protocol as at the time they could do what they wanted.
