Maybe it is a real faulty one.

I saw in another forum one person purchased one like this and she says that vendor is selling scam. In fact, there are chips with 2.1 but they can read can bus, this one is worst than 1.3. I hope I get a full refund... Thanks for your opinion.

This is what I get when test the interface. I bought it as elm 1.5 but it seems that is 2.1! COMMAND: ATZ RESPONSE: ELM327 v2.1> COMMAND: ATI RESPONSE: ATI ELM327 v2.1> COMMAND: ATE0 RESPONSE: ATE0 OK> COMMAND: ATL0 RESPONSE: OK> COMMAND: ATH0 RESPONSE: OK> COMMAND: ATSPC RESPONSE: OK> COMMAND: ATS0...

I tried one more time and it doesn't connect on can bus.

Every module: engine, body computer, instrument panel...

My car is Fiat Punto mk2 1.2 16v 2000.

Hello Alfaeddy

Can you help me with this interface, please? Which resistor should I remove? Thank you.

I don't know how what else can I do to this to work. The elm is in com port 3 but in every automotive software I tried, they didn't find anything on com port 3. I already changed latency time, tried ftdi drivers, changed another settings in com port... I know the elm work because it work with alfaOB...

I think my elm is really soldered, not plugged. I will try move it back and forward.

Edit: Doesn't work unless I brake the connectors. I think I will sawing them.

It is not possible to unplug the upper board. Unless I cut the pins.

I'm sorry for the pictures. I will take more and better. In the first one I only wanted to show that I can't separate the two boards because the pins are soldered together.

Are you saying that to read the 2000 punto it is necessary the resistor? I don't know what is motorECU.
