U050DInvalid Data Received From Wireless Accessory Charging Module A
- Generic OBD-II code · Network
- How the car detects it
- The wireless accessory charging module is the inductive pad for phones, almost always following the Qi standard, which Toyota was first to offer from the factory, on the 2013 Avalon. The module reports charging state, phone detection and faults to the infotainment or body controller, which shows the charging icon. Ford calls it WACM; for 2018–2022 models it documented slow or no charging and phone mispositioning messages with MagSafe iPhones, advising a check with another Qi phone before replacing parts (SSM 50982). That is a compatibility issue, not U050D. The code itself means the WACM's status frames arrive but are invalid. No maker publishes it. U020C means the module is not heard at all.
