Application
This unit describes the skills and knowledge required to diagnose complex faults in mobile plant braking systems and determine the repair action necessary to restore system performance. It involves confirming the existence of a fault, developing a diagnostic testing strategy, diagnosing the cause of the fault, 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.
The unit applies to those working in the automotive service and repair industry. The braking systems include those of agricultural machinery or mobile plant machinery, which may be wheeled or track type machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessment Conditions
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 mobile plant braking 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 mobile plant braking system specifications
- braking systems of three different mobile plant with complex faults
- mobile plant braking system diagnostic equipment, including:
- scan tool
- brake performance test equipment
- oil pressure gauge
- accumulator pressure gauge
- component wear gauge
- tools, equipment and materials appropriate for diagnosing complex faults in mobile plant braking systems.
