Frequently asked questions about U062C

What does U062C mean?

Lost Communication With A/C Refrigerant Distribution Valve Actuator “C”. The control module stopped receiving expected network messages from the A/C Refrigerant Distribution Valve Actuator “C” node on the vehicle communication bus.

Is U062C generic or manufacturer-specific?

U062C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U062C 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 U062C is removable in your case.
