Service and repair light vehicle lift assisted suspension systems


Application

This unit describes the performance outcomes required to service, locate and repair faults in hydraulic or pneumatic light vehicle lift assisted suspension systems. It involves preparing for the task, servicing, repairing and post-repair testing the system, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry. The lift assisted suspension systems include those of light vehicles, four wheel drives or light commercial vehicles.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

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 light vehicle lift assisted suspension systems that they have serviced 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:

mechanical repair workplace or simulated workplace

workplace instructions

manufacturer specifications for light vehicle lift assisted suspension system

two different light vehicles with lift assisted suspension systems requiring service and repair

tools, equipment and materials appropriate for inspecting, servicing, repairing and adjusting light vehicle lift assisted suspension systems.
