U0529Invalid Data Received From Door Window Motor G
- Generic OBD-II code · Network
- How the car detects it
- With G, J2012 reaches the seventh and last window motor slot, more than most vehicles will ever use. No manufacturer publishes U0529 or names a window for G. Should the code appear, it follows the logic of its siblings: motor G is heard on the network, yet its frames are rejected because of a checksum or counter error, a signal marked invalid or a value outside the agreed range. Supply problems are a frequent trigger, since lift motors draw high starting currents; NXP's MM908E624 design reports overvoltage and overtemperature in its status for that reason. For diagnosis, watch the reported position while operating the window and check supply and ground before replacing the motor. U0228 means the motor is silent.
