    Hi Colin,

    The schematic looks good, just several reminders below.

    There is no SPLIT pin on TCAN1043A-Q1, the pin on the device is NC which means no need to connect this pin, so C307 is not needed.

    R301 and R302 are NC, please make sure the termination value is correct, CAN requires about 60 Ohms on the bus to work.

    Ensure the TVS diode and bus filters are placed close to connector.

    Regards,

    Sean
