Required Skills and Knowledge


This section describes the skills and knowledge required for this unit.

Required skills 

  • collect, organise and understand information related to work orders, plans and safety procedures for servicing, repairing and testing electronic anti-lock braking systems
  • communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems
  • plan and organise activities, including preparation and layout of worksite and obtaining of equipment and material to avoid backtracking or workflow interruptions
  • work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
  • use mathematical ideas and techniques to correctly calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks
  • use pre-checking and inspection techniques to anticipate planning and scheduling problems, avoid wastage of time and material
  • use workplace technology related to the service and repair of electronically controlled anti-lock braking systems, including the use of specialist tooling and equipment, measuring equipment, computerised technology and communication devices and the reporting/documenting of results

Required knowledge 

A working knowledge of:

  • OHS regulations/requirement, equipment, material and personal safety requirements
  • operating principles of electronic anti-lock braking systems
  • construction and operation of electronic anti-lock braking systems
  • types and layout of service/repair manuals (hard copy and electronic)
  • relationship to other electronically controlled systems, including shared components (e.g. ECUs, sensors)
  • testing, diagnosis and fault determination procedures
  • servicing/repairing, removal, replacement and adjustment procedures relevant to application
  • work organisation and planning processes
  • enterprise quality processes

Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

It is essential that competence in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances in the critical aspects of:

  • observing safety procedures and requirements
  • communicating effectively with others involved in or affected by the work
  • selecting methods and techniques appropriate to the circumstances
  • completing preparatory activity in a systematic manner
  • testing, inspecting and evaluating electronic anti-lock wheel systems, speed sensors and related components
  • diagnosing and determining the repair/replacement requirements to rectify faults
  • servicing/repairing electronic anti-lock braking systems to manufacturer/component supplier requirements
  • completing the work within agreed time
  • completing workplace and equipment documents.

Context of , and specific resources for assessment 

Application of competence is to be assessed in the workplace or simulated worksite.

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with regulatory requirements, including Australian Standards.

The following resources should be made available:

  • workplace location or simulated workplace
  • material relevant to the service and repair of electronically controlled anti-lock braking systems
  • equipment, hand and power tooling appropriate to the service and repair of electronically controlled anti-lock braking systems
  • activities covering mandatory task requirements
  • specifications and work instructions.

Method of assessment 

  • Assessment must satisfy the endorsed Assessment Guidelines of AUR05 Automotive Industry RS&R Training Package
  • Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge
  • Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies
  • Assessment may be applied under project related conditions and require evidence of process
  • Assessment must confirm a reasonable inference that competence is able to be under the particular circumstance, and is able to be transferred to other circumstances
  • It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements
  • Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
