New unit of competency. |
Application
This unit describes the performance outcomes required to diagnose faults in complex vehicle, vessels or machinery systems to determine the repair action necessary to restore system performance. It involves confirming the existence of a complex system fault, choosing the required diagnostic procedure and tools, applying the diagnostic procedure, reporting conclusions, and making repair recommendations.
A complex system integrates two or more automotive systems, or incorporates three or more mechanical, hydraulic, pneumatic, electrical or electronic sub-systems. Examples include electronically controlled automatic transmissions, anti-lock braking systems, and engine management systems integrating ignition, fuel and transmission control systems.
It applies to those working in the automotive service and repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Elements and Performance Criteria
Elements Elements describe the essential outcomes. |
Performance CriteriaPerformance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Identify and confirm work requirement regarding complex system fault |
1.1 Nature and objective of diagnosis requirements are determined from workplace instructions 1.2 Existence of fault is confirmed from direct or indirect evidence 1.3 Information, including customer complaint, is sourced to provide a full overview of all faults and conditions under which they occur |
2. Analyse information |
2.1 Function and operation of the system when operating correctly are identified 2.2 Information is analysed and affected systems are identified 2.3 Manufacturer specifications and other technical information are accessed and interpreted 2.4 Tests are identified and selected from range of available options, and testing sequence is established 2.5 Testing equipment is obtained and prepared according to manufacturer specifications and workplace procedures 2.6 Tools, equipment and materials required to support the diagnostic process are identified, selected and prepared for use 2.7 Hazards associated with the work are identified and risks are managed according to workplace procedures and safety requirements |
3. Perform diagnosis |
3.1 Tests are applied systematically and efficiently to gather precise data on system operation according to manufacturer specifications, workplace procedures, and safety and environmental requirements 3.2 Test results are compared with manufacturer specifications and conclusions are drawn and documented according to workplace procedures, including recommendations for necessary repairs 3.3 Diagnostic findings are verified, as required, by using reliable alternative or optional process according to manufacturer specifications and workplace procedures 3.4 Conclusions are provided to appropriate personnel or customer to confirm further action to be taken |
4. Complete work processes |
4.1 Vehicle or machinery is presented ready to be repaired or returned to the customer 4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected 4.3 Tools and equipment are checked and stored according to workplace procedures |
