U0525Invalid Data Received From Door Window Motor C
- Generic OBD-II code · Network
- How the car detects it
- Data from window motor C include what the door controller needs for automatic closing, which in the United States falls under FMVSS 118. A window able to close without the switch being held must stop and reverse before it presses on a test rod of 4 to 200 mm with 100 N or more, and then open again by at least 125 mm or far enough for a 200 mm rod. If the reports from motor C are corrupt, the controller can no longer rely on that reversal, so a cautious design blocks one-touch and remote closing for this window. No manufacturer documents U0525 or names the door behind C. Raising and lowering with the switch held usually still works; U0224 is the lost-communication partner.
