The smart decoder is used when the vehicle's computer performs a verification of the original bulbs to inform the driver of the fault using a display in the dashboard of the vehicle. The smart decoder also allows a "pulsed" current (as shown in the diagram to the left), frequently encountered in American vehicles such as Ram and JEEP, much like the DRL decoder, to provide a steady current coming from the car computer to the LED bulb.
WHY USE AN INTELLIGENT DECODER AND IN WHAT SITUATIONS
IN WHICH CASE A DRL DECODER WILL NOT BE THE SOLUTION FOR YOUR PROBLEM
In some American vehicles (Cherokee, 300, Charger) and some Mercedes that have a greater sensitivity to the variances of the bulb charge than the majority of manufacturers. If the original bulb has 55w and your AIS LED bulb has 30w, a 25w loss is perceived by the computer, which will turn on a burnt bulb signal on the dashboard. In some cases, such as the American models, the light circuit may shut down after a few days during an automatic test. Despite the fact that the Intelligent AIS decoder adds 5w to the circuit for a total of 35w and works in most cases, the vehicles listed above are more sensitive because there is still too much of a difference. In this very specific case, you will have to use the relays with capacitor with the Add-a-circuit option and our 55w resistor sets from AIS. Contact your representative for further questions.
