Frequently asked questions about U02A2
What does U02A2 mean?
Lost Communication With Reductant Quality Module. The control module stopped receiving expected network messages from the Reductant Quality Module node on the vehicle communication bus.
Is U02A2 generic or manufacturer-specific?
U02A2 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U02A2 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 U02A2 is removable in your case.
