Release 1	New unit of competency.

Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

diagnose and repair a fault in three of the following heavy vehicle emission control systems:

closed crankcase ventilation system

exhaust gas recirculation system

diesel engine particulate filter system

selective catalytic reduction system.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing heavy vehicle emission control systems, including procedures for working safely with engines producing toxic emissions

environmental requirements, including procedures for containing and disposing of emission control system fuels, fluids and components

heavy vehicle emissions and their effects on the environment and health:

carbon monoxide

oxides of nitrogen

ozone

sulphur dioxide

particulate matter

hydrocarbons

application, purpose and operating principles of heavy vehicle emission control systems and components, including:

closed crankcase ventilation system

exhaust gas recirculation system

diesel engine particulate filter system

selective catalytic reduction system

catalytic converter system

diagnostic testing procedures for heavy vehicle emission control systems, including:

closed crankcase ventilation system operation

exhaust gas recirculation system operation

diesel engine particulate filter system operation

selective catalytic reduction system operation

catalytic converter system operation

exhaust gas analysis

repair procedures for heavy vehicle emission control systems, including procedures for removing, replacing and adjusting the system components

post-repair testing procedures for heavy vehicle emission control systems.

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 heavy vehicle 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 heavy vehicle emission control system specifications

heavy vehicle engines with faults in the emission control systems specified in the performance evidence

diagnostic equipment for testing heavy vehicle emission control systems

tools, equipment and materials appropriate for repairing, replacing and adjusting heavy vehicle emission control systems.
