Application
This unit describes the performance outcomes required to inspect, diagnose and repair alternative fuel systems in heavy vehicle engines. It involves preparing for the task, inspecting the system and selecting the correct diagnostic procedure, carrying out diagnosis and repair work, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working on the alternative fuel systems of agricultural machinery, heavy commercial vehicles, marine vessels or mobile plant machinery.
Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
inspect, diagnose and repair alternative fuel systems in two different heavy vehicle engines.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to inspecting, diagnosing and repairing alternative fuel systems, including procedures for:
working with alternative fuel systems
selecting and using personal protective equipment (PPE)
environmental requirements, including procedures for preventing fuel leakage from fuel systems
operating principles of alternative fuel systems
application, purpose and function of alternative fuel systems
inspect and repair procedures for alternative fuel systems
diagnostic testing procedures for alternative fuel systems
post-repair testing procedures for alternative fuel systems.
Assessment Conditions
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 alternative fuel systems that they have inspected and repaired, 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 alternative fuel system specifications
two different heavy vehicle engines with alternative fuel systems requiring repair
diagnostic equipment for alternative fuel systems, including exhaust gas analyser
repair tools, equipment and materials for alternative fuel systems in heavy vehicle engines.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.
Skills | Description |
Learning skills to: | locate appropriate sources of information efficiently. |
Reading skills to: | interpret information from manufacturer and workshop literature when seeking alternative fuel system specifications and procedures. |
Writing skills to: | legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used. |
Oral communication skills to: | clarify instructions. |
Numeracy skills to: | measure alternative fuel system components and use basic mathematical operations, including addition, subtraction, multiplication and division, to calculate distances, areas, volumes, tolerances and deviations from manufacturer specifications. |
