U0526Invalid Data Received From Door Window Motor D
- Generic OBD-II code · Network
- How the car detects it
- Not every lift motor carries Hall sensors. Patent US11611297 describes a cheaper approach in which the controller derives speed, current and how quickly current changes from the ripple that commutation leaves in the motor current, and recognises a pinch from those values. Positions obtained this way are sensitive to supply noise and brush wear, so the data reported by window motor D may drift out of the plausible range and lead to U0526. No manufacturer publishes this code or says which door uses letter D. Practical effects resemble the sister codes: express and comfort closing disabled, a lost end position, sometimes a window that halts part way. U0225 is stored instead when motor D does not answer at all.
- What you may notice
- Window halts part way or misjudges its end position
- Express and comfort closing unavailable
