Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to inspect and service emission control systems on petrol or diesel powered engines. It involves preparing for the task, inspecting the system, reporting the inspection findings, servicing and adjusting the system, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The emission control systems include those of agricultural equipment, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycles or outdoor power equipment.This unit does not include emission control systems associated with engine management systems.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 emission control 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 emission control system specifications

two different vehicles or machinery with emission control systems requiring servicing

equipment, tools and materials appropriate for inspecting and servicing emission control systems.
