FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello Giuseppe1374

Your request is too short?
Readers of this thread always believe in connection difficulties
would lie on the interface there.

First of all!
Which vehicle?
which control?
you want to read?


Have you installed the best driver?
Have you done all the settings correct?
If the COM port for your interface run without error?

And add to that that your interface has no bridge resistance
and thus should have no problem CAN bus.
In addition to the settings or the driver is not correctly

Hi Eddy I have a NISSAN Tiida 2005, Japanese, driver wheel CHANGED, I bought an interface ELM 327 V 1.5a (CHINA). i connect ELM327 to my PC taking consideration port configuration, result is ok configuration port, PROTOCOL OK, but not connected to Engine ECU. MY QUESTION IS PERHAPS IS THE INTERFACE ELM327 NOT COMPATIBLE WITH MY JAPANESE CAR ? Please what should i do in that case? ... THANK YOU IN ADVANCE. I also want to say i remove Resistor 121 (my ELM 327 IS Acoording images) and it does not connect to ECU also. But i tried it in another car ELM327 INTERFACE TOYOTA YARIS 2008, ORIGINAL driver wheel, and works perfectly, read everything, DIAGRAMS, water temperature engine, it means that got connect to Toyota ECU . do i have to change the ELM 327 to my Nissan Tida? or there are some solution to this ELM·"/ to Japanese CArs....

I appreciate your time to help. Thanks in advance

I have trouble connecting on many cars, you only have good connection on the engine control unit for the rest everything is bad! driver I put the ones you recommended settings are good, I have another elm327 (metal box) and it works well, this instead (photo I posted) does not work well, for example if I go to the real-time values ​​elm327 back to home.
ps Mr. Eddy I could apply the fix network "can" page 1?

Hi Fremelectric

I do not know why you can not establish or bad connection to your Nissan?
What software do you use?
Certainly not Multiecuscan!!

Because, depending on the software used these bridges Resistor is required or not

So I think since you have error setting or the interface is faulty.

Hi Giuseppe 1374

Try it out this bypass is provided by ELM Electronics in the circuit diagram,
It can only get better, because even with these two bypass
Multiecuscan works with this interface

And then write about it here in the forum if there is an improvement or not.
Worse, it can not be.

hello eddy I tried the solution of the page 1of this topic and it seems to work fine, now I have last problem I can not make a diagnosis of the values ​​in real time, if the machine is in motion my elm327 is not found, it tells me the door comX not found and does not enter the diagnosis, the cable is in the picture, multiecuscan 1.4, windows 7 32bit, the drivers recommended by you.

hi eddy, yes i use multiecusacan but it just support Fiat Alfa Romeo and other, tell me if i can use Multiecuscan to my Nissan Tiida Latio 2005, i have ELM 327, cause i tried with all option in multiecuscan (alfa Romero, Fiat, etc). Configuration in ports is OK. Please what do i need to conect to my ECU nissan with ElM 327?
Thanks in advance.

Hello Giuseppe

First of all, I'm surprised your success

I had this circuit in an ELM interface and built-in times.
But no difference to the other ELM interface in the usual shops
may notice

There may be a fault in the door control. Take a one Proxi Aligment
and try again

Hello Fremelectic

I do not think you can read your Nissan with Multiecuscan!
Since Nissan does not have any Bosch or Marelli control.
What control does it really?

You need a compatible software for Nissan.
