U0207Lost Communication With Moveable Roof Control Module A
- Generic OBD-II code · Network
- How the car detects it
- U0207 concerns moveable roof control module A, the electronics of a power sunroof or glass roof. GM uses it: the 2011 Saab 9-5 list names the moveable roof control module, and GM preliminary information PIT5606J (GMC Acadia, Cadillac XT5 2017–2021) counts U0207 among the codes that appear after water gets in – mostly at the upper windshield corners hidden under the glass, rarely past the outer sunroof seal or a drain hose – or when the dash harness rubs at the steering column. Since roof modules sit in the headliner close to the drains, a leak can reach the unit or its plug. A sunroof that ignores its switch is the usual sign; U020A is the second roof unit, U0508 invalid data. No MIL.
