[cuongttco]

Hi everybody!
Can i make by my self an simple OBD2 error reader tool?
If you think it possible? Can you show for me?
I only need them to read error code?

Hello,

Why don't you pay for a simple OBD interface ? It's cheaper (less than 60 euros) and you can read your fault code very easily.
If you want to build your own interface, it cost more expensive than an ELM327 interface.

But it's your choice.

Hello, If you want to do it by your own you can go to Elm Electronics (http://www.elmelectronics.com) and there are schematics for constructing your ELM 327, you can buy the ELM chip from there too.
Then you can find software here like SCANXL, SCANMASTER, etc.
