U052AInvalid Data Received From Heated Steering Wheel Module
- Generic OBD-II code · Network
- How the car detects it
- The heated steering wheel module powers the heating mat in the rim and reports its state, such as heater on or off, the requested level and the rim temperature read by an embedded thermistor, to the body or climate network. A receiver that gets these frames but finds the content implausible (temperature out of range, bad checksum or counter, wrong length) logs U052A; if the frames stop entirely, U0229 is set instead. Ford shows that the hardware depends on the option: if adaptive steering is fitted, heating is a job of Ford's SECM, the steering effort controller inside the wheel, otherwise of a separate HSWM (SSM 47850). No bulletin names U052A itself. For the driver the rim may stay cold, switch off early or show no status; steering is unaffected.
