This cable allows you to connect your CMDFlash to Temic DSG DQ250 controllers. This can be used to read out the original file when virtual read fails, 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 a DB9 plug for a direct connection to the CMDFlash interface.
