capacitor - Bulk Current Injection on CAN bus

I'm trying to understand how the Bulk current injection would look like on the CANH and CANL lines, to understand the overloading of the ESD protection diode on the CAN lines and capacitors in parallel to that on the CANH and CANL lines. During BCI, what would the waveform on CANH and CANL lines look like ? I cannot find this anywhere on the internet, could anyone suggest suitable sources of information.
