FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[puntomjtd1234]

hello Alfaeddy
Yes, as you said the resistance r04 it connects the pins that you have said.
I have succeeded in removing the plastics even if I have made a small damage.
I add the photo of thing it is possible to see without the plastics
I thank a lot You for your help, tomorrow I remove the resistance and then I will make some tests, I will make you know the result of the tests.
Complements for your technical preparation.

Hi puntomjdt1234

Properly, remove the resistor R04 and your ELM interface can also read the CAN bus protocols

Your ECU and ABS (adapter) you could also read before that??

Hi Eddy
Also removing the resistance the situation is unchanged with the same problems.
I believe that my interface is defective.
What do you think ?
Do you know an interface low cost but that don't have problems?

thanks

Hello Puntojtd1234

For the reason I have already written to you that you are with the ELM in the original version your ECU can read the ABS must

You made the wrong settings

Only for CAN bus controllers you need to remove the resistor

Sorry Eddy, I got it wrong!
So, you think there's a wrong setting.
The Bluetooth connection is correct because the interface is connected to the computer.
When I do the scan for the interface tells me ok.
Then when I do the test interface connection, it is sometimes ok and sometimes not ok.
In the end, however, the interface does not connect not even engine's ecu.
Can you offer any advice in this situation?
Thanks for your patience .

Hi

Hmmmmm??
Have you asked the Latency Time in 1?

Install the newest driver? http://www.ftdichip.com/Drivers/VCP.htm

The Com port checked?

The Multiecuscan settings checked?


What appears on the desktop when the connection fails?

Thanks Eddy.
I'll check the things that you said.

[ELIO65]

can not read the number of the Chip in an red frame ?

I think your Problem ist not the ELM

Control your Setting / Interfaces Setting / Com port /
and you can read your ECU

For ABS / Airbag / usw. you need an yellow Adapter

Hi Eddy, the Chip is MCP2551.
I control setting, interfaces setting, com port, but I can't connect with Multiecuscan.
The interface works fine with Torque and EasyObdII.

I made two new photos. I hope they are better.
Can you help me again?

Hi Elio65

How many of these different mid ELM 327 interface you've got?

viewtopic.php?f=5&t=1493&start=590

I see no errors on this board, but the pictures are not good
And I do not know this board

So I guess a setting mistake

Greetings Eddy

[ELIO65]

I have only this last one!
Thanks anyway!
