AURETA004
Analyse and evaluate electrical and electronic faults in convenience and entertainment systems


Application

This unit describes the performance outcomes required to analyse and evaluate electrical and electronic faults in the embedded network convenience and entertainment systems of vehicles or machinery in order to initiate action to sustain, vary or enhance performance. It involves identifying, evaluating, selecting, justifying and documenting the most appropriate rectification method or variation to the rectification method. The unit includes the analysis of multi-system and intermittent faults which may be caused by operating in adverse conditions.

It applies to those working in the automotive service and repair industry on network convenience and entertainment systems in vehicles or machinery.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
