Vehicles currently using this faster CAN FD protocol include many General Motors and Ford 2019 and 2020 vehicles. Vehicles currently using this faster CAN FD (CAN Flexible Data-Rate) protocol include many General Motors and Ford 2019 and 2020 vehicles. CAN FD is one of the newer communication protocols, noted for being faster, more reliable and more secure. Autel says its MX808, MS905, MS906, MS906BT, MS906TS, MS908, MS908S, MS908P, MS908SP, MSELITE, IM508, IM608 tablets will be able to diagnose CAN FD-equipped vehicles when the adapter is plugged into the VCI directly as in the case of the smaller VCI units or into the OBDII cable that is connected to the larger VCIs and into the vehicle’s OBDII port. Autel’s latest MaxiSYS tablet releases, the MaxiSYS Ultra, MaxiSYS 919 and MaxiSYS 909 do not need Can FD Adapter to communicate CAN FD-equipped vehicles, as these new tablets come with enhanced VCIs that include many of the new protocols including CAN FD.
