This unit describes the performance outcomes required to diagnose and repair faults in the starting systems of vehicles, vessels or machinery. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working in an automotive service and repair industry. The starting systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycles or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 starting 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 specifications for vehicle, vessel or machinery starting systems
two different vehicles, vessels or machinery with starting system faults
diagnostic equipment for vehicle, vessel or machinery starting systems, including multimeter
tools, equipment and materials appropriate for repairing vehicle, vessel or machinery starting systems.
