U0228Lost Communication With Door Window Motor G
- Generic OBD-II code · Network
- How the car detects it
- U0228 concerns door window motor G, the last letter of this group. No manufacturer documents U0228 publicly. GM shows that a networked window motor does not automatically mean these generic codes: in the 2011 Saab 9-5 the body control module runs the front passenger and driver motors as devices 0 and 4 on LIN bus 3 and the two rear motors on LIN bus 4, and flags a lost motor with GM's own U1530, U1534, U1540 or U1544. Some motors do without Hall sensors; a Gentherm patent derives speed and pinch events from the current ripple, which still calls for electronics at the motor and thus a bus node. Which door carries G is up to the maker. No MIL.
