Description
This unit describes the performance outcomes required to diagnose complex faults in hybrid, plug-in hybrid and battery electric vehicle (HEV, PHEV and BEV) embedded network management systems and determine the repair action necessary to restore system performance. It involves confirming the existence of a fault, choosing the diagnostic procedure and tools, applying the diagnostic procedure, reporting conclusions and making repair recommendations. Importance is placed in the unit on applying electrical safety procedures when working on high voltage (HV) rechargeable energy storage systems (RESS).Complex faults are outside the normal scope of a technician’s diagnosis and repair work. They include intermittent faults, multi-system faults, faults introduced as a result of system repairs, and indirect faults caused by the influence of external systems, requiring the application of complex diagnostic processes to resolve.It applies to those working in the automotive service and repair industry. The HEV, PHEV and BEV network management systems include those of light vehicles or heavy commercial vehicles. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
