CAN communication

2002 XJR - Conductors between the CAN network modules carry a digital signal? Can I read/confirm it? How do I know (verify) whether it is there, or if it is a "correct" signal?
Thank you

Only using oscilloscope. You can very roughly measure signal levels using multimeter. If bus is broken. You can measure end terminal resistances when the bus is powered off.
