Application
This unit describes the performance outcomes required to analyse and evaluate electrical and electronic faults in the embedded network management systems of hybrid, plug-in hybrid and battery electric vehicles (HEV, PHEV and BEV) 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. Importance is placed in the unit on applying electrical safety procedures when working on high voltage (HV) rechargeable energy storage systems (RESS).
It applies to those working in the automotive service and repair industry on HEV, PHEV or BEV embedded network management systems.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
