Performance Evidence

The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including evidence of the ability to:

diagnose a complex fault in three different engine management systems in which the work for at least two of the systems must involve a different complex fault from the following:

an intermittent fault

a fault that affects more than one system

a fault introduced as a result of a system repair

an indirect fault caused by the influence of external systems

develop a testing strategy to diagnose the causes of the complex faults in the above systems.

Knowledge Evidence

The candidate must be able to demonstrate knowledge to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including knowledge of:

methods to locate and interpret information required to diagnose and repair complex faults in engine management systems, including:

engine management system manufacturer specifications

information from customers and supervisors

workplace procedures required to diagnose and repair complex faults in engine management systems, including:

establishing the serviceability of tools and equipment

documentation procedures

housekeeping procedures, including:

examination of tools and equipment

storage of equipment

identification, tagging and isolation of faulty equipment

safe disposal of materials

recycling procedures

workplace health and safety (WHS) requirements relating to diagnosing complex faults in engine management systems, including procedures for:

testing procedures for engine management systems, including procedures for:

dynamic and static testing of vehicle or machinery

component failure analysis

types and key features of diagnostic testing equipment required to diagnose complex faults in engine management systems, including:

scan tools

oscilloscopes

procedures for accessing and interpreting scan tool system data, including:

diagnostic trouble codes (DTCs), including:

conditions that set the DTCs

conditions for running DTCs

live data

freeze frame data

waveforms.

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 engine management 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 engine management system specifications

three different vehicles or machinery with complex faults in their engine management systems

engine management system diagnostic equipment, including scan tools and oscilloscopes

tools, equipment and materials appropriate for diagnosing complex faults in engine management systems.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
