NOTE:
CRP123X or CRP123 older version does not have CAN FD compatibility. Requires CRP123XV3.0.
CRP919E/X BT (the Bluetooth version) has built-in CAN FD protocol, does not need a CAN FD adapter.

How to connect Launch CRP919E/CRP919X/CRP123X V3 with CAN FD adapter?

Connect one end of the CAN FD adapter to the CRP919E/CRP123X V3 main cable.


Connect the other end of the CAN FD adapter to vehicle’s OBD socket.
