canbus system

Canbus is short for Controller Area Network Bus, which can monitor the condition of your vehicle and send data to correspondent control units. This technology is originated in Europe. So vehicles like BMW, Audi, Volkswagen, Mercedes, Porsche and some of the American vehicles. It is a good idea to check the manual or asking the vehicle dealer whether the vehicle you purchased is equipped with Canbus or not before replacing any electrical products.

When do I need a Canbus driver?

If you occur the problem above, that means your vehicles need Canbus driver. The easiest way is referring to the vehicle’s suppliers. If you are still not sure, you can check it in this way. Remove a parking light, not a turn signal or brake light. Then drive the vehicle around during the daytime with the parking light button being on. If your vehicle gives you a “bulb-out” signal, it means your vehicle is equipped with Canbus. If not, that means it is not equipped with Canbus.

For vehicles without Canbus, you can change or add any electrical products you like. While for vehicle equipped with Canbus, you can also change the electrical products but you still need one more thing to make that happen—Canbus Driver. After adding the Canbus Driver to the headlight bulbs, “bulb-out”, flashing and most problem occurred would be fixed.

Thus, in order not to occur any problem while upgrading your headlight, you’d better make sure whether your vehicle is equipped with canbus or not. If so, buy the Canbus Driver as well.
