Nothing to do with CANbus. Power supply control monitors current flowing through bulbs, if it is out of specification it gives error. LED's use less power, therefore less current flowing which makes power supply control to think bulb has gone open circuit. Depends how tight tolerances are on each car. Our D2 and C5 did not need 501 LED's with built in built in resistors or extra resistors, worked fine with regular 501 LED's(but shows fault if no bulb or bulb open circuit), friends B6 was showing fault with regular LED's for sidelight 501's but it is fine with the ones that has built in resistors. It could be that current tolerances are tighter on D3.
