This cable allows you to connect most flash tools to Temic DSG DQ250 controllers. This can be used to read out the original file direct from the DSG connector as reading over OBD in tricore versions of DQ250 is not possible (type Exx and Fxx).
It can also be used to read/write all versions of DQ250 on the bench (type Cxx, Exx and Fxx).
The cable has both K-line and CAN wired (with integral termination resistor) and is fitted with an OBD2 female plug allowing connection any flash tool with an OBD2 cable.
