FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello celenlee

First off, your remote Resistor has formed a bridge at pin 6 & 7 of MCP2551?
Not einface remove a resistor if you do not know what this is. !

Then another, what car / control you want to read?
Because the resistor prevents only the CAN bus or not combined!
No other logs


And even if you can not make a test interface, this is due to your wifi
Connection and not your vehicle connection

1- The 121 Ohm resistor formed a bridge between pin 6&7 of MCP2551 (Pin 6-14 of OBD), and I removed this.

2- I want to use this interface on Grande Punto. (Engine ECU and Selespeed ECU)

When I look at the board I do not see the 100Ohm Resistor+ 560pF cap. ?
Is it true to add these missing parts to use on Grande Punto?

Hello

At 1 Yes

Ad 2 You can read without the yellow adapter

This pass (resistor + capacitor) was still required for any of my many ELM Interface!

Either the settings is incorrect
or the ELM is defective.

Hello reeper72

Remove out the white plug housing on the board (8 Pin)
And possibly even a picture of the back!

Since I can not take the time to browse this thread

Hello, after several trials this interface does not communicate with the ECU of my volvo v70 2.5 2000, can anyone help me?

great work, was able to get my elm327 on to the can bus

Hello,
i'm Marco and i need your help in order to connect my Elm327 1.3 to my Giulietta '11.

With my interface i can read all parameters, but now i need to update the Proxy Alignment (i've added Blue&me interface)

What resistor i have to remove to my interface in order to work properly with multiecuscan 1.7?

On pcb is written "ELM327-USB V.3.0"

My interface is the following:




Thank you in advance for your help

Bye

Hi Marco

If you can read the parameters of your Giulietta with your interface, you've got connections to your Giulietta. ?

Thus, it may be no fault bridges resistor.

To run the proxy you need the yellow adapter!
Have you used the??

Also, you can hardly see anything on your images are too small (pixel) and white plugs obscured much

Hi Alfaeddy
thank you for your reply!
Yes, I can read the parameters of my Giulietta, but when I try to align the proxy (using the Yellow adapter), sometimes the procedure of alignment starts but in most of case after the configuration of one/two modules the procedure fails.
Could be an error due to high latency?

I try to post other images, and I hope they will be useful:

[Alfaeddy]

Hi Marco

One more time!
If you can connect to your Giulietta, it may not be due to a resistor bridge.

But still, the white plug on your images

Your latency time have you yes safe according to the information provided by Yani back?
Otherwise, try it just once with other times when you suspect an error there.

And if the proxy starts Aligment and only after a certain time, breaks
is it possibly to the settings of the connection.
Or checked the proxy controller sends no signal and the proxy aborts the connection. ?

Hi Alfaeddy,

I've tried all the possible settings for the connection (included the information provided by Yani), but unfortunately any news.

So I decided to go to the Alfa Romeo dealer and solve the proxy alignment

Thank you for your support.

Hi

Does the Alfa dealer can make the proxy alignment??

Sorry I could not help you
