[QUOTE="aidilj, post: 497233, member: 20536"] The BMW diagnostic bus is on ISO-K line, this is the information from wiki ISO 9141-2. This protocol has an asynchronous serial data rate of 10.4 kBaud. It is somewhat similar to RS-232, however the signal levels are different, and communications happens on a single, bidirectional line without additional handshake signals. ISO 9141-2 is primarily used in Chrysler, European, and Asian vehicles. [LIST] [*]pin 7: K-line [*]pin 15: L-line (optional) [*]UART signaling [*]K-line idles high, with a 510 ohm resistor to Vbatt [*]The active/dominant state is driven low with an open-collector driver. [*]Message length is restricted to 12 bytes, including CRC [/LIST] I think here it is best to keep the k line wire as short as possible and transfer most data on USB bus/ ethernet. This is what they have been doing for PAsoft and yellow diag head. Gonna shorten the cable when I have the time.. Thanks guys [/QUOTE]
