DO I REQUIRE AN ADDITIONAL CANBUS MODULE?
Once you know the globe type you need, working out if you require an additional canbus module is quite an easy process. Most STEDI LED Conversion kits come with a CANBUS module inbuilt but there are the odd exception with some vehicles requiring an additional CANBUS to overwrite the vehicles computer. If you didn't unplug the globe in the search for what connection you needed you will do so for the purpose of this test.
Once a light is unplugged just switch on the ignition and turn on your headlights. Looking at your dash you now may or may not have an error icon/message regarding the headlights (Globe Failure). If no message has appeared you do not require an additional CANBUS Module. If you have a dash notification there is a chance you will need an additional CANBUS Module to install an LED Conversion. Below is an explanation to how the CANBUS systems work, unfortunately the only true form of working out if a model of car requires an additional CANBUS is through trial.\
HOW DOES A CANBUS MODULE WORK?
These are available in the same format as the LED conversion i.e H7, H4 etc...
Most modern vehicles have systems in play that moderate things like doors being open, faults in certain components, lights bulb blown etc... This system monitors the amp draw that your lights consume to work out if the light is functioning correctly. This type of system is compatible with the included CANBUS with your LED Conversion kit. Some vehicles not only monitor amps but voltage as well, this is where the additional CANBUS comes into play.
The additional CANBUS Module overwrites the vehicles computer into ignoring the additional current draw & voltage LED lights require. Note that additional CANBUS decoders are only required for low beam upgrades.
IMPORTANT: Please note that our H4 CANBUS uses resistors to turn voltage into heat. It is normal for the decoder to get very hot. For the reason we recommend you strictly secure it to a metal part of your engine bay.
