Application

This unit describes the skills and knowledge required to diagnose complex faults in engine management systems and identifying the repair action necessary to restore system performance. The systems used vary based on the work context. It involves confirming the existence of a fault, developing a diagnostic testing strategy, diagnosing the cause of the fault, reporting conclusions and making repair recommendations. Complex faults are outside the normal scope of a technician’s diagnosis and repair work. They include intermittent faults, multi-system faults, faults introduced as a result of system repairs, and indirect faults caused by the influence of external systems, requiring the application of complex diagnostic processes to resolve.

The unit applies to those who work in the automotive service and repair industry. The engine management systems include those in vehicles from all sectors of the industry.

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

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.

  • 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.
