Fiat Marea ECU Read Code

Good evening, sorry for my broken English.
Can tell who transfer protocol data to the Fiat Marea 1.8 16v 98 years of release.

I know that I have installed ECU
Hitachi S/N EGE109127181
0464359010
MFI-0 09 DD4 7Z11

Do not by ignorance...
Or protocol data from the Fiat Marea and Fiat Doblo same or not?
Thanks from Russia :-)

Re: Fiat Marea ECU Read Code

Welcome to FIATForum

I think the Doblo and 98 Marea have different protocols. The Doblo should be OBDII but the MK1 Marea will use Fiats 3 pin connection.

I am unsure if that answers your question. What is it you are trying to do?
Thanks TLW thanked for this post

Re: Fiat Marea ECU Read Code

Thank you.....
All can be ...
in the OBD-II is used as K-Line, L-Line, 12V, GRND.

Fiat Marea 3pin (K-Line, L-Line, 12V)
12V for alarm about reading. But I can not find any protocol and OBD-II is whether.

Even waiting for a response from the representation of corporations Hitach. that they can learn about the ECU, as in Russia or who have not been able to answer me

Re: Fiat Marea ECU Read Code

i dont think i understand what you are trying to do?

are you trying to 'remap' the ECU? or just Read error codes?

Re: Fiat Marea ECU Read Code

Just in Russia there is a bluetooth-ecu device designed to work with the Doblo and some other machines I want to read not only error codes and reading the current parameters (speed, speed, temperature, etc.)


Here and want to learn how the protocols can be considered these options, then get the opportunity to use the device to Doblo.


Due to the fact that there are many protocols, such as for example: OBD, OBD-II etc. and the lack of information to me and had to turn to you because you are not times already discussed such problem

Re: Fiat Marea ECU Read Code

I think I understand what you want now.

You already have a bluetooth ODB-II device which is compatible with the Doblo?
But you wish to know if it can be connected to your Marea?

I believe the answer is yes it can. However I'm not an expert on this and can only go on information I have read previously. It requires you to make a wiring harness of you own so the OBD-II port can connect to the Fiat 3 pin port.

We do have a member or two who is well versed in this process and I'm sure will be able to help you more. But ofcourse that depends on if I am correct on my assumption?

Re: Fiat Marea ECU Read Code

yes, it may well work, as you said you can use the K line on OBD-II to connect to the Fiat 3 pin.

Quote Quote:
OBD Connector Pins 3 Pin Connect on car
Pin 5 - Signal Ground__________Black = signal ground (to ECU)
Pin 7 - K Line________________White = K line (to ECU)
Pin 4 - Chassis Ground________the remaining pin, although any good earth will do.
Pin 16 - Battery Power (+12v)________Direct to battery positive terminal.
