FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello

Your ELM interface works as it is.
There must be nothing changed or removed.

You have to make the Bluetooth connection as the first course.
Check the settings
Then your interface should be able to also read

Hello Edy,

No,does not want to go... I don't know what to do;
I install all the drivers correctly, I reinstall the windows (win7 x32), but nothing, the same problem, I can read only the ECU modul;

Can you suggest me anything else?

Thank you,

[Alfaeddy]

hello

Which driver do you have installed?
automatically or this one?

With the green adapter you can also use the ABS and steering read, right?
These controls can not be read via CAN bus, as well as the engine ECU

Your board is constructed as of Yani in the first post is described.
Thus, it should work fine.

hello,

I have a 327 ELM 1.5a (metallic case) I can scan the engine of my Alfa Romeo 159 2.0 JTDM but impossible to go into the service menu to make a counter reset drain.


Do I need a special cable, yellow?

Thank you for your return.

Hello

No, you have to remove the resistor R2 and then this works

Well, I think that's very crazy, but go to the facts:

Searching diferences among VAG and ELM pinouts, found...
PINS .. ELM ..... VAG
4-5 .... linked ... none
7-15 ... linked ... none

Looking for why this...


First step I linked pins 4-5 and... NO CONNECTION

Second step: linked pins 7-15 and... NO CONNECTION YET

So, I clicked "Scan For Interfaces" and... WOW!

but, FOR GODD, I have only one.

Testing both...




and...................................... BINGO!!!

NEWS, IF INTEREST YOU...

Today my interface did not work. So did several attempts and finally figured out why: in addition to configuring TWO interfaces (a "real" COM port and another "ghost", seen only by MES), it is definitely necessary that the first interface is the "real" and the the second the "ghost", instead, DOES NOT WORK !!!

So it was not necessary to link the pins 4-5 and 7-15, just a mistake of mine, among many changes.
