Description
LAUNCH • X431 adapter CAN FD
This adapter cable from LAUNCH enables X-431 diagnostic scan tools to work with modern vehicles using the CAN FD (Controller Area Network Flexible Data-Rate) communication protocol—a protocol not supported natively by some Bluetooth connectors on older devices like the X431 PRO3S+, PADIII, and PAD V/II. Intended for professional technicians, this adapter turns older X-431 models into powerful tools capable of reading fault codes, streaming live data, and performing special functions on late-model GM, Jaguar, Land Rover, Ford, Audi, BMW, BMW Mini and similar CAN FD-equipped vehicles. It plugs into the vehicle’s diagnostic link connector via the VCI main cable for reliable signal conversion and high speed diagnostics.
