U0229 Lost Communication With Heated Steering Wheel Module

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.

Likely causes

Module without fuse feed or ground
Heated wheel disabled from the factory (GM RPO 00G), code to be ignored
Clockspring interrupted (when the module sits in the steering wheel)
Heated steering wheel module failed or not configured

Symptoms

  • Steering wheel heating does not switch on
  • Heater button indicator does not respond
  • Code stored without any noticeable fault (feature not fitted or disabled)
