Dear Rondo Wang,
According to the datasheet of the UJA1169:
CAN FD-passive is a feature that allows CAN FD bus traffic to be ignored in Sleep/Standby mode. CAN FD-passive partial networking is the perfect fit for networks that support both CAN FD and classic CAN communications. It allows normal CAN controllers that do not need to communicate CAN FD messages to remain in partial networking Sleep/Standby mode during CAN FD communication without generating bus errors.
Please be aware that the UJA1169 exists in six different versions, please remit to Table 1 of the respecting datasheet for more information:

Also, please consider the following feature of this SBC family:
-ISO 11898-2:201x (upcoming merged ISO 11898-2/5/6) compliant 1 Mbit/s high-speed CAN transceiver supporting CAN FD active communication up to 2 Mbit/s in the CAN FD data field (all six variants).
Best regards,
Ruben
