Application

This unit describes the skills and knowledge required to diagnose complex faults in light vehicle steering and suspension systems and determine the repair action necessary to restore system performance. 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 working in the automotive service and repair industry. The steering and suspension systems include those light vehicles or light commercial vehicles.

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

S KILL 

DESCRIPTION 

Learning

  • Locates required sources of information efficiently
  • Develops own approach to a task, including steps to confirm findings.

Reading

  • Interprets workplace instructions such as job cards
  • Identifies, organises and interprets technical information from manufacturer and workshop literature when seeking steering and suspension system specifications and procedures.

Oral communication

  • Clarifies instructions
  • Obtains information from customers and supervisors.

Numeracy

  • Measures steering and suspension system components and uses mathematical operations, to calculate tolerances and deviations from manufacturer specifications
  • Uses electrical measuring equipment and interpret units, such as amperes, ohms, and volts.

Planning and organising

  • Plans own work requirements
  • Prioritises and sequences actions to achieve required outcomes
  • Ensures tasks are completed within workplace timeframes.

Technology

  • Uses specialised diagnostic equipment.

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 the following three systems:
  • steering system of a light vehicle
  • suspension system of a different light vehicle
  • steering or suspension system of a third light vehicle
  • the above work must involve developing a testing strategy to diagnose the cause of at least two of the following types of complex faults:
  • an intermittent fault
  • a fault that affects more than one system
  • a fault introduced as a result of a system repair

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 light vehicle steering and suspension 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 light vehicle steering and suspension specifications
  • three different light vehicles with complex faults in their steering and suspension systems
  • steering and suspension system diagnostic equipment
  • tools, equipment and materials appropriate for diagnosing complex faults in steering and suspension systems.

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