Frequently asked questions about U0229

What does U0229 mean?

Lost Communication With heated steering wheel module. The control module stopped receiving expected network messages from the heated steering wheel module node on the vehicle communication bus.

Is U0229 generic or manufacturer-specific?

U0229 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U0229 at file level?

Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U0229 is removable in your case.
