U0205 code meaning
Lost Communication With Door Control Module G
What U0205 means
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.

What each part of U0205 means

What to do next
- Note U0205 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
