After this initialization it is expected to continue communicating at 10k4 baud. After this, the verhicle will respond with key bytes 0x08 and 0x08 or 0x96 and 0x The sync byte with key bytes of the verhicle must be acknowledged by the microcontroller by inverting the second key byte.

This will end the initialization part of ISO The response of ISO is slightly different. The verhicle ECU will also respond with synchronization byte 0x Only the key bytes are different.

In case of a VW Touran of the key bytes are 0xef and 0x8f. Also here the second key byte must be acknowledged by the microcontroller by inverting it. After the initialization process it is possible to submit a request to the verhicle ECU. A request is a sequence of bytes where adressing, a mode, a PID and a checksum is present.

The following are example requests:. The first three bytes are for addressing. The fourth is the mode field. The fifth byte is the data field with the PID and the last byte is the checksum. In this example mode 1 is used. This mode will show "current data" as how it is at this moment. This mode is perfect for displaying actual information. The data field contains the PID. In this case 0x0d which is the verhicle speed. The checksum is the sum of the bytes with mod See this link for a list of PIDs:.

The response is almost similar. The data field reflects actual data which will probably change every request.

The following are example responses with 0x00 as data which is verhicle speed 0. The verhicle will supply the circuit with 12 volt via pins 5 and 16 of the ODB2 connector. The voltage regulator will create 5 volt out of this for the microcontroller and LCD. K-line signals of pin 7 will be converted to appropriate levels via an interface of resistors and a transistor. On port RC7 you can connect a buzzer optional. When the engine coolant temperature PID 0x05 exceeds the 93 degrees this port will be enabled.

A routine for displaying and clearing stored diagnostic trouble codes is included. This can be initiated by pressing the switch for 2 seconds. This routine is untested and will most probably not work.

Feel free to try if you have a car with trouble codes. The 5 baud init is also called "slow init".
