Rotax does not publish a public decoder mapping for FC_Class/Type/Test/Error tuples. Codes are classified by the class field, which the community and BUDS UI conventions associate with the broad subsystem. A Rotax-trained mechanic with BUDS access can resolve the full tuple to a specific cause.
Eight curated charts grouped by subsystem. Each has one primary axis on the left and at most one secondary axis on the right. Hover and zoom sync across all charts — drag any chart to zoom, the others follow. Click a legend item to hide that line. Reset zoom
Select a fault to highlight its timestamp on every chart and see the engine state captured at that moment.
All fault snapshots plotted across ECU run time. Each row groups by subsystem. Click a marker for the engine state captured at that moment. Vertical alignment across rows reveals fault clusters — events that fired within seconds of each other and often share a root cause.
Click a fault marker above to see the engine state captured at that ECU timestamp.
