FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

Hello Alfaeddy

The first picture is the mini elm that isn't able to separate the two boards, those pins are soldered at the two ends. Should I cut them? Then the black plastic will secure them, I think.

The second picture is the bigger elm without the resistor. MES and AlfaOBD don't detect it but is detected with apps in smartphone.

Hello Zafron

Your pictures are very very very bad , Sorry
In the first picture of the Mini ELM I can not see anything
The upper board is installed, the you need can pull off

At the second board you have the correct resistor removed
have the point, again marked, as I only bad on this picture
can detect whether something has been done.

You should not use flash when taking photos.


But again, the bridge resistance only affects CAN bus protocols
So the Punto of 2000 must be read with the resistance MotorECU.

I'm sorry for the pictures. I will take more and better. In the first one I only wanted to show that I can't separate the two boards because the pins are soldered together.

Are you saying that to read the 2000 punto it is necessary the resistor? I don't know what is motorECU.

[Alfaeddy]

MotorECU = Engine Control

It is not possible to unplug the upper board. Unless I cut the pins.

Hi everybody from Italy, I have this chinese elm 327
But as most of us it can't connect to some voices of multiecusan on my stilo 1.9 jtd 16v/multijet overhall for the serveice reset. It is the same circuit of thath blue above.

Which resistor I have to operate?
Thanks a lot for your work!

Hi

I know of 3 different circuits of the circuit board on these mini ELMs
You have to open it so you can see in this thread which board
your ELM corresponds

Greetings Eddy

Look it is the same above of zafron.

[Alfaeddy]

Hi

Then you should also remove the red marked resistor

One thing...i'm not able to unpair the two board. Do i have to unweld the contacts?
