Application
This unit describes the performance outcomes required to analyse and evaluate electrical and electronic faults in embedded network air conditioning and heating, ventilation and air conditioning (HVAC) 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 the air conditioning and HVAC systems of vehicles or machinery.
Licensing requirements apply to this unit. Users are advised to check with the relevant regulatory authority.
