Most definitely your OBD library that is not up to date.

PROTO_KWP2000_FAST is defined in OBD.h.

You could try to update the following folder: "CodeBlocksDir\arduino\libraries\OBD" with the files from your download in "libraries/OBD".
You could also update the other libraries as well.

I've figured it out!
Using your latest code and some modifications I got it working like a charm.

First of all the protocol was KWP2000Fast so in config.h I used:
#define OBD_PROTOCOL PROTO_KWP2000_FAST

Futhermore the init is slightly different (obd.cpp)
const char *initcmd[] = {"ATZ\r ...

I have no newer car available to test this on right now. So I have to get back at this in a few days/weeks.

In the meanwhile is there an option to show the RAW commands that are send and received with the car?

My config looks like this:

#ifndef CONFIG_H_INCLUDED
#define CONFIG_H_INCLUDED

/**************************************
* Choose model of OBD-II Adapter
**************************************/
// OBD_MODEL_I2C for I2C version
// OBD_MODEL_UART for UART version
#define OBD_MODEL OBD_MODEL_I2C ...

Hi,

I've received the logger a few days ago but I am still struggling to read out a single car. I've successfully uploaded the firmware and after connecting the kit to the OBD port I get the screen stating the following:

- ACC check
- GPS check (searching)
- OBD error/cross

I've tried to connect ...
