- Generic OBD-II code · Network
- How the car detects it
- U020D is the second wireless charging slot, B, meant for vehicles with two inductive pads, for example a further one for rear passengers. No manufacturer documents this code publicly. The early GM system shows what sits behind such a unit: preliminary information PIC6049 (2015 Cadillac ATS, CTS, Escalade, Chevrolet Tahoe, Suburban, GMC Yukon with option K4C) placed the wireless charging module under technical assistance restriction and asks for phone model, receiver cover and charging habits before any replacement. A pad that pauses because the phone is hot is no network fault. A genuine U020D means pad B stays dead while pad A still charges. U020C covers pad A, U050E invalid data. No MIL.
