U0506Invalid Data Received From Door Control Module G

  • Generic OBD-II code · Network
How the car detects it
G is the seventh door slot and in practice belongs to cars that number their door electronics from E upwards. Ford does so with DCMG, the third of four latch modules in Mach-E, Aviator and Nautilus; Ford service messages name DCMG together with its siblings whenever latch software is updated. GM's Saab 9-5 code list contains no partner entry U0205, so the slot appears unused there. The code means a receiving controller judged DCMG's lock and door-state messages invalid, while U0205 stands for missing messages. Because e-latch doors have no mechanical outside release in normal use, a module sending bad data can leave one door that does not open from the handle or triggers door warnings.
