FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

Hi Walter

Oh OK, just an example

No this is not a VAG / KKL, the interface on the picture is a ELM 327 Bluetooth
really

Hi everyone.

I have a problem connecting Multiecuscan to an Abarth grande punto 2008 with a 1.5 elm bluetooth.

I receve this error message:



"Attention this interface is not compatible elm 327 1.3. Not will connect to any module can!"
And i can't use nothing of the program...

Into the test interface connection multiecuscan detect a 1.5 elm device...........

This is my elm interface, but my is bluetooth, whit classical blue module:



With other software i can connect to the interface (torque, scanxl,ecc......).
Where is the problem?

Thanks to everyone

I nave removed the r4, but the problem remains...
Some ideas??

Hi Walter

Sorry sorry

I probably brought some confusion

But when I see your test from the KKL, the latency time is still very high

Why I do not try it again, without the hooks I "high Latency Time mode" as then change the latency times.

Or'll try another com port

I think it is because of the high times.

Hi Pieropara

Yes some ideas that have been written a hundred times but here.

- Bluetooth connection created?
- Which driver?
- Comport settings?
- Other settings?
- Interface defective?

Ok, Eddy...

All ports that I tried results the same. I´ll verify the resistance and another PC or notebook, maybe, but on next days...

Bad news! I removed the resistor and now the elm doesn't work at all. The led is on but software cannot found it...

[Waltomatic]

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!!!

Hi

Then you have destroyed more than the resistor of CAN bus protocol interferes

Hello Walter

Nice to see your link now works
but I do not quite understand what you did ????

Pin 4 and 5 are always connected (mass)
Pin 15 is no longer needed since the system is outdated.
the pin 15 is no longer occupied in the vehicles

But why is your Latency Time have improved ?????
