Diagnose complex system faults

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the performance outcomes required to diagnose faults in complex vehicle, vessels or machinery systems to determine the repair action necessary to restore system performance. It involves confirming the existence of a complex system fault, choosing the required diagnostic procedure and tools, applying the diagnostic procedure, reporting conclusions, and making repair recommendations.

A complex system integrates two or more automotive systems, or incorporates three or more mechanical, hydraulic, pneumatic, electrical or electronic sub-systems. Examples include electronically controlled automatic transmissions, anti-lock braking systems, and engine management systems integrating ignition, fuel and transmission control systems.

It applies to those working in the automotive service and repair industry.

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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

diagnose complex system faults on three different vehicles, machinery or vessels

the above diagnosis must involve two of the following types of complex faults:

one fault that is in a complex system that integrates two or more automotive systems

one fault that incorporates three or more mechanical, hydraulic, pneumatic, electrical or electronic sub-systems.

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing complex system faults in vehicles, vessels or machinery, including working safely with the systems being tested, including procedures for:

selecting and using personal protective equipment (PPE)

using tools and equipment

types, application and operation of complex systems, including:

systems that integrates two or more automotive systems

systems that incorporate three or more mechanical, hydraulic, pneumatic, electrical or electronic sub-systems

diagnostic procedures for complex systems, including stages within the diagnostic procedure

methods of gathering information on complex system faults, including customer questioning techniques

types and applications of diagnostic flow charts

types, applications, limitations and operation of diagnostic tools, including:

multimeters

scan tools, including:

diagnosis trouble codes (DTC) and the conditions that caused the code to be set

live data

snap shots

oscilloscopes

mechanical, hydraulic and pneumatic test equipment

methods of differentiating between fault symptoms and fault cause.

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 vehicle or machinery complex system faults that they have diagnosed, 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 system specifications

three different vehicles, vessels or machinery that have the complex system faults specified in the performance evidence

tools, equipment and materials appropriate for diagnosing complex system faults in vehicles, vessels or machinery.
