KWP2000 through K-line

[Javi]

Hello,
I need a VI that can communicate my PC with an ECU (Electronic control unit) through a k-line. I know the only solution is to use the serial port together with a voltage adapter to change from the serial communication to the Keyword Protocol 2000.
I have been searching for a VI but there is nothing in the web. Could someone help me?

Thanks.
Javi.

Hello Javi,

some references I've been able to find are here:

If none of these companies can provide you the libraries, I recommend you to contact NI Alliance Members, specially those with automotive experience, as they may be able to develop the libraries -in case they don't have them already-.
You can browse Alliance Members worldwide at NI's web page:

Hello, I hope that  this thread is not closed.

I has built an interface  k-line but i can´t initialize it at 5 baud for ISO-9141.

Do anyone knows how to do it?

Hi Jawier,

Were you able to find something for the 5 baud initialization?

I'm struggling with these right now and havent been able to find something on these.

I'm trying to start communicacion with they Fast Initialization or the 5 baud initialization.

I would really appreciate any help.

Hi

We have a ECU controller supporting K-line serial interface.

NI does not have any supporting hardware for k-line interface.

Can I use k-line to USB converter to establish communication with PC using LabVIEW VISA?

Converter link:

or else please suggest other better methods, if any.

Thanks
