AURTTL014 Analyse and evaluate faults in gas fuel systems
Assessment tool
Version 1.0 Issue Date: June 2024
This unit describes the performance outcomes required to analyse and evaluate faults in gas fuel systems 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. The gas fuel systems include those of agricultural machinery, heavy commercial vehicles, forklifts, light vehicles or mobile plant machinery.
Licensing, legislative, regulatory or certification requirements apply to this unit. Users are advised to check with the relevant regulatory authority.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
