Actually everything is working well FES wise, which makes me think it is actually an genuine ELM1.4
- NO communication problems, all ECU are recognized.(Airbag and steering not tested, pins 1-7-9 not soldered yet)
- NO problem to get access to service reset.
- NO installation problem. Just the drivers for FTDI USB to install.
Hi guys, I have the same interface, same board but it was sold to me as ELM 1.3a, i can connect to the engine but i cant access service reset, instrument panel or any other.. I have a Lancia Ypsilon 1.3 jtd (2003)
Do I have to sold any pins? I checked http://www.multiecuscan.net/SupportedVehiclesList.aspx and shows (ELM) only for what i need (service reset)...
please help
No mate you don't need to soldering any pins.
Your interface isn't work on CAN.
What you have to do is to soldering between pins 6 (of your interface) and ground and between 14 pins (of your interface) and ground a resitor and a capacitor.
resistor=100Ohm and capacitor =560pf
For all support to fix your interface you find here.

I did it and it worls like a charm.
Good luck

thanks for replying mattydr67.
I'm almost sure i don't need to do that because i have the interface you can see here viewtopic.php?f=5&t=1493&start=10 or here download/file.php?id=239
As you can see "On the last pic we can see the 100 Ohm resistors (R25/R26) for CAN H/L lines with associated capacitor (C14/C15)"
So I just can't understand why i can't connect anything on can bus, I'm thinking to buy another one.. any advise?

Do you have Croma from 2005/6... or Croma from 1992/3...???

If you have Croma from 2005/6... you need commercial version - you need to buy registration key!!!

On the last pic we can see the 100 Ohm resistors (R25/R26) for CAN H/L lines with associated capacitor (C14/C15)
Same combo shown by members in the last posts.

Hope it can help you to find the correct interface

i have the same elm but on my 147 1.6 i can't establish connection with service indicator. i can only see the engine in scanning mode! what is wrong?

If it is Croma after 2005 you need the commercial version.
It works like charm.
The best.
