U0229Lost Communication With Heated Steering Wheel Module
- Generic OBD-II code · Network
- How the car detects it
- U0229 means the heated steering wheel module no longer answers. GM PIT5883G (December 2022) explains one harmless case: many 2022–2023 GM models were built during a parts shortage with the heated wheel disabled (RPO 00G); there U0229, together with U152B or U1530, may be stored, should be ignored and lights no warning. Ford SSM 47850 shows why the module's location varies: on cars with adaptive steering, heating is handled by the SECM, a steering effort controller inside the wheel, while other cars carry a separate HSWM. Power for the rim heater and its thermistor passes through the clockspring, as a Ford patent illustrates. U052A covers invalid data from the module. No MIL.
