Using SoftwareSerial over 38400bps can cause loss of data. In your case, simply use an Arduino MEGA which has 4 hardware serial UARTs. If MEGA 2560 is too big for you, check out this:

Pin 7 is used by KWP2000.

ISO-9141-2 is supported. It's different from ISO-9141.

All these modes are supported by the adapter. But your car's ECU may not respond to some of them.

What car?

Arduino Telematics Kits are designed to putting up a data logging and monitoring device with OBD-II, GPS and motion sensor data access.

The Users Guide for Arduino Telematics Kits contains information to get start with the kit and the Arduino sketch designed and provided for them.

Thanks!

You can modify the code and outputs anything you want to know via Serial.

Thank you for your order. I saw you have chosen XH-2.5 Connector (4-Pin x 1) in your order.

The connector must be attached. You can add a comment when placing an order for no case and cable.
