How do I know if my car has canbus wiring?

How do I know if my car is equipped with CAN Bus? If the vehicle warns you when a bulb is out, it is equipped with CAN Bus. The easiest way is to contact the vehicle’s supplier or dealership. If you’re still not sure, we normally tell customers to remove a light and drive the vehicle to see if it gives a warning.

What is the difference between CAN bus and K-Line?
