DOIP :

With Diagnostics over DoIP, diagnostics introduced over UDS are used over TCP/IP and Ethernet. This enables much higher data rates than with CAN. That makes LAUNCH CRP909X save both in terms of time and expenses in the case of complex diagnostic tasks and flash applications. Compatible with BMW (F&G chassis), Volvo models (2018 later), Land Rover & Jaguar models (2017 later).
