Question about my Brava and OBD...

Dear friends,

first of all, congratulation for this great site and forum. I'm italian and I never found sites related to bravo/a world like this, in Italy!!!

Second: sorry for poor english language, i'm not too able to write english correctly :D

After some stupid engine fault on my Brava 1.4 12v (1997) I tried to learn some trick about fault blink codes on Bosch Mono Motronic ECUs, downloading something on the net.

I found only infos about 1.5.5 , 1.7 and other ecus, but nothing about 1.7.3.

Do you know if auto-diagnosys and blink codes are similar to 1.7 ECUs? Where can I find description of the pinout of the diagnose connector? (I found only a 3 pin connector near the ecu, i suppose it's the diag. connector, but i find only 2 wires, one black and one white/orange it seems). And do you know if this connector may be connected to an obd cable to make diagnosys with a PC? what's the protocol of this ECU?

Sorry for so many questions...

Best regards

Luca

Don't worry about your English.
From what I've seen, you'll put many on here to shame on that score!

Cool site...

... but there are no topics about 3 pin fiat diagnostic connector :( :(
 
Re: Cool site...

Tom, do you know if fiat ECUs are almost OBD compliant?

And do you know if I can activate blink codes connecting the two wires with a jumper?

See you
 
Re: Cool site...

The 1.2 and JTD are ODB but the rest are not.

Blink codes are only available on ECUs designed to give blink codes. Just because one type of bosch ECU gives them does not mean all do. Each ECU is custom designed for the car its fitting and the particular car maker.
