    Normal incandescent bulbs have a filament wire that creates the light. The filament acts like a resistor....when the bulb stops working the ecu detects a change in resistance... That's what gives you the "Bulb Out"... Led lights don't typically show a proper resistance so the ecu thinks the bulb is out. Some companies add a shunt resistor to their led lights to fool the ecu. These led lights are listed as CAN-bus compatible. Search for CAN-bus compatible led bulbs on the interwebz or placeing a small piece of black electrical tape over the irritating indicator light also works....:D

    Coding. Have the bulb check turned off (with a half dozen other things turned on).

    Metalman nailed it. If you do a little research you can find a resistor to add that will make it work right.
