FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Rate]

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.

hola gente, tampoco puedo comunicarme con ecu de abs epb, sera problema de mi obd2? mi obd2 es elm327 hs-pro
si pueden ayudarme agradeceria.

saludos.

Bonjour, malheureusement vos images n'apparaissent pas... Un lien peut-être? Merci par avance.

This is my ELM327 - one part is missing (I've marked it with an arrow). Could this be causing the connection problem?

Buonasera, ho trovato una ELM327 della quale il venditore mi ha assicurato, anche con una foto del circuito stampato, che sono presenti i chip PIC18f2480 e non il PIC18f25k80 e come convertitore Seriale ==> USB utilizza il FTDI FT232RL e non il CH340 , chip che come ho letto sono molto più compatibili e performanti.
L'ELM presenta però un interruttore, cerchiato in rosso. Da quanto ho capito, questo commutatore serve per commutare tra due diversi protocolli di comunicazione CAN bus, solitamente denominati HS-CAN (High Speed) e MS-CAN (Medium Speed). La mia domanda è sapere se è compatibile con i veicoli FIAT tramite il programma MULTIECUSCAN. Allego anche foto dello stampato dove ho la certezza dei chip usati Grazie

Good evening, I found an ELM327 of which the seller assured me, even with a photo of the printed circuit board, that there are the PIC18f2480 chips and not the PIC18f25k80 and as a Serial ==> USB converter uses the FTDI FT232RL and not the CH340, chips that as I read are much more compatible and performing.
The ELM, however, has a switch, circled in red. From what I understand, this switch is used to switch between two different CAN bus communication protocols, usually called HS-CAN (High Speed) and MS-CAN (Medium Speed). My question is whether it is compatible with FIAT vehicles via the MULTIECUSCAN program. I also attach photos of the print where I have the certainty of the used chips Thank you

Compré este, y solo pude hacer el reset del aceite y entrar al cuadro, me deja quitar o poner el pitido del cinturón, al resto no me deja acceder, será la misma resistencia? Al quitarla no provocará algún otro problema? Seguirá funcionando para ford? Gracias por las respuestas.

I bought this one, and I could only reset the oil and enter the box, let me remove or put the beep of the belt, to the rest does not let me access, will it be the same resistance? When you remove it, it will not cause the fun another problem? Will it continue to work for Ford? Thanks for the answers.
