Do all cars have CAN bus?

As technology advances, more and more cars are equipped with the CAN (Controller Area Network) bus. This is a system that allows different parts of the car to communicate with each other, improving the efficiency and performance of the vehicle.

However, not all cars have the CAN bus system. This depends on the year, make, and model of the car. Older cars may not have the technology to support the CAN bus, while newer cars typically do. Some luxury and high-end cars may also have more advanced versions of the CAN bus system.

While having the CAN bus in a car is becoming more common, it is not necessary for the car to function properly. It is simply a tool that can improve the performance and efficiency of the car’s systems.
