Good morning everyone :D

please help - which resistor blocks the CAN connection. Specifically, I want to make a Ducato.
Maybe you could help me for a moment? Thank you.

tzok wrote: 10 Dec 2010, 21:59 I've got 2 ELM327 interfaces, both labeled as 1.5a, but they differ even in the way they blink the LEDs during the power init procedure. None of them don't want to connect to my Grande Punto when using SCANTOOL.NET (I've set vendor ID to SCNATOOL.NET via terminal AT@3 command). I've borrowed an identical to one of my own interface from a friend of mine and it worked just fine. All interfaces worked fine with ScanMaster-ELM. Unfortunately I had to give it back before the FES v.2.6 was released. None of mine ELMs did connected using 2.6, but both work with 2.6.1?!? I didn't tried it with registered version, but FREE opened a connection, so I assume it will work (hope so, because I've just bought FES).
The intricacies of ELM327 interfaces and their compatibility can be perplexing. Your detailed exploration, including adjustments via terminal commands and varying results with different software versions, highlights the complexities users might face. It's encouraging that FES v.2.6.1 seems to provide a working solution for your ELMs, adding a positive note.[

Hello,

I have a elm1.5a cable and am having issue connecting to my Giulia using MultiECUScan. I have tested the connection using MultiECUScan and get an error: WARNING: this interface is not compatible with ELM 327 1.3!

I have tested the resistance between pins 6 and 16 and I get 120, so I think I do have the resistor.

Please can someone let me know which resistor on this board type I need to remove

Does anyone know what is the last version of driver for the PL2303, i recently bought a ELM327 usb and it has that chip. So im wondering what is the last version of drivers that windows 10 still supports. And if anyone know which resistor should be removed on the elms with pl2303 chip, Thanks...

on official Prolific website there are drivers for PL2303

I found the right driver, the latest drivers on ther site dont work. It says phased out since 2012, i found another driver from 2008 which works now i only need to figure out what resistor i need to remove.
