Frequently asked questions about U0302
What does U0302 mean?
Software incompatibility - transmission control module (TCM). The control module detected a fault associated with the Software incompatibility - transmission control module (TCM) circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is U0302 generic or manufacturer-specific?
U0302 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U0302 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 U0302 is removable in your case.
