Not sure what 5d90 is. Try resetting the ecu and other stuff in the bt software or driving it awhile and see if it goes away. If it's a sensor, sometime you can disconnect and reconnect while the car is on and that reestablishes the connection. You then stop and restart the car and the codes vanish. These cars have minds of their own...
