FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[hero_1016]

Did i buy a Dud, this does not look right at all ? :/

Mine looks nothing like anyone elses on here, is mine a China-fake? It doesnt even say "ELM327" on it.

I have the same and don't know what to do!

Hi Guys
I want to share with You all what I came across when looking here and there how to do proxi alignement in my 2003 punto 1.2 8v.
I've got two interfaces from aliexpress with which I managed to succesfully do proxi alignement:
1) you must desolder from pcb - Big thanks to oskar69 from page number 227
It is this one: OBD2 Car Diagnostic Tool elm 327 HS CAN /MS CAN ELM327 USB V1.5 FTDI/CH340 PIC18F25K80

Then desolder 1200 resistor (120 Ohm resistor) between pin 6 and pin 14, it is located near pins for OBDII socket, you will manage to find this

2) you don't need to solder anything: Vgate vLinker FS ELM327

I was able to connect with MES and have no problems so far.
Wish you luck

Thank you very much for share info,Vgate vLinker FS ELM327 work excellent on Multiecuscan.

Dear All

What is meant by desoldering the resistor

remove the resistor leaving the circuit is open?
Or connect the two terminals after removing the resistor?

Thanks in advance

The resistor has to be REMOVED.

Technically the resistor is a Bus Terminator. All CAN-Bus have to have a termination of 120 ohms. However this termination is already present on the Body Computer so having two terminations kills / reduces the data signal. Hence the need to remove the terminator in the ELM interface.
