Application
This unit describes the performance outcomes required to diagnose complex faults in light vehicle or light commercial vehicle embedded network safety 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.
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 vehicle network safety systems include those of light vehicles or light commercial vehicles.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the light vehicle safety systems that they have worked on, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
- automotive repair workplace or simulated workplace
- workplace instructions
- manufacturer light vehicle safety system specifications
- two different light vehicles or light commercial vehicles with complex faults in their safety systems
- light vehicle safety system diagnostic equipment, including:
- digital multimeter
- scan tool
