1. A hierarchical diagnostics electrical architecture for a vehicle, the vehicle comprising a plurality of on-board computing devices for hosting the hierarchical diagnostics electrical architecture, and the hierarchical diagnostics electrical architecture comprising:
a component diagnostic layer comprising a plurality of electronic control units each comprising a diagnostics server module arranged to:
receive sensor output data from one or more on-board vehicle sensors; and
perform one or more diagnostic tasks based on the received sensor output data to generate one or more component-level diagnostic notifications; and
at least one supervisory diagnostic layer arranged to receive the component-level diagnostic notifications from each of a group of the plurality of electronic control units, wherein the at least one supervisory diagnostic layer is arranged to perform arbitration management across multiple diagnostic testers.
