    Hi Priyanka,

    This is most likely due to CANL exposed to voltage spikes above the abs max ratings. Please verify the voltage levels on an oscilloscope during connection, disconnection, or active vehicle communication.

    Also ensure the dongle's GND potential do not differ significantly from the vehicle CAN GND during plugging and unplugging while powered, thanks.

    Best Regards,

    Michael.
