U0205Lost Communication With Door Control Module G
- Generic OBD-II code · Network
- How the car detects it
- U0205 covers door control module G. The generic list reserves eight door module slots, A to H, so G only comes into play on vehicles carrying more door electronics than four side doors; which unit gets the letter is the maker's choice. No manufacturer documents this code publicly. Door modules usually run windows, locks, mirrors and switch lighting and often act as master for small LIN nodes like a window lifter or mirror switch. For comparison, Chrysler bulletin 08-061-12 on the 2005–2010 300 and Charger first has the battery disconnected for about a minute and orders a new door module only if it still stays off the bus. Invalid data from unit G is U0506. A MIL is not expected.
