FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[mattydr67]

Hello,

Another cheap 'Chinese clone', from eBay (UK seller, not china or HK), received 3 days ago.
It was sold as ELM 327 1.4 'with a genuine ELM chip'.
(For my personal information, I would really like to recognize a genuine ELM chip from a fake one)

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

HI.I have a cable with the first post and is adapted from a dealer for program.Test shows OK but can not reset or info / FiatCroma / ELM 327 (EuroScan 2010) CAN USB v1.4a.Help.Thank

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?

[nickromano]

also I tryied to test my interface inside FES and these are the results :

COMMAND: ATZ
RESPONSE: ATZ
ELM327 v1.3a
COMMAND: ATE0
RESPONSE: ATE0
OK
COMMAND: ATL0
RESPONSE: OK
COMMAND: ATH0

RESPONSE: OK
COMMAND: ATST41
RESPONSE: OK
COMMAND: ATBI
RESPONSE: CAN ERROR
COMMAND: ATZ

looks like it's not working in CAN but I have resistors and capacitors in the right place.. what does it mean..

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

Best regards

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.
