The same problem with ELM 327 Bluetooth.
I'm OK to all commands.
I could connect to the engine but can not anymore. I used to remove R-4 - no connection
Used a system of resistors and now I join with the engine but can not anymore. Scanning can not be performed in the well. Ok for all commands and shows it is still version 1.4

Hello Fiat Bravo Emotion

Which vehicle do you want to read?

If you get a link to your ECU but no CAN bus connection, it can only be to the resistance at the MCP2551 chip?!

Open your interface and make two images, then I can specify error.
and Mark.

Greetings Eddy

Hi Eddy,
I tried to Punto FL 1.3 MJet and Bravo's 2007 Multijet. Only Engine module was fully functionally.

I see I have that the same ELM as betyargabor from 36 page of this threat has. I will try with R04 resistor first :) I have little of time now.

Hi,

I confirm information about R04 in my ELM327 Bluetooth interface. Just removed R04 resistor (hidden by wires on first picture) by kitchen knife and works great.

Lukasz

Hello Lukasz

It could also only be the known resistor problem.
And reallythis resistor is below the connectors on the board

Nice to see your ELM interface now works :D

I have also wired ELM327, which is often used by me in cars. But in Bravo I had a problem with Lambda sensor and bought ELM327 Bluetooth for Bravo 07 to test Engine errors. Cover is screwed by three screws, which I don't like unscrew. Now I will install ELM327 Bluetooth and close cover. I will read data without unscrew the cover :) I don't trust ELM327 Bluetooth to do Proxi or something more than simply reading data, delete service on dashboard or do some actuator tests.

Thank You for interest of my problem :)

Regards,
Lukasz

Hmmmm?

You can even make a connection, but this is terminated immediately
It may be a case of only a connection error
Either your interface has an error, or your laptop

Do you have the possibility to use a different time laptop?

To provide the service back must not run the engine, it is sufficient to
Insert key and the dash board lights to let burn

Otherwise, I can help you no longer instantaneous, Sorry

...back. I just get one new cable, same ELM327 1.4 USB, the PCB is v3.0 USB, aaaaaand f****ng same results. So connecting to engine only, the rest is just pop-up for 2 secs then the multiecuscan is going back to main menu.
Any idea? If i remove the R4 resistor on the top right?
Or if somebody can link one cable from ebay what is 100% working on fiat (doblo), i will be pleased. Thanks

Hello Siscoo

Please make an even better picture of the white plug
Can I remove the white plastic?
In the area I need to find the disturbing resistor.

Of the images is not that noticeable


Greetings Eddy

Edit:

I mean the plastic with 8 pins
