Required Skills and Knowledge


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

Required skills 

  • collecting information from a variety of sources to ensure the major component can be serviced to achieve the manufacturer/component supplier intent
  • discussing job card requirements and vehicle symptoms with the customer
  • following up fault diagnosis outcomes, which may also require ongoing consultation with the customer to confirm a course of repair action
  • servicing and fault rectification procedures need to be followed in a set order as specified in workshop manuals and other technical publications to achieve a serviceable outcome within efficient timeframes
  • the servicing of components requires cooperative working arrangements with colleagues and supervision relating to sharing of specialist equipment, sharing of technical knowledge and the procurement of spare parts
  • establishing safe and effective work processes which anticipate and/or resolve problems and downtime, to systematically develop solutions to avoid or minimise reworking and avoid wastage
  • using mathematical ideas and techniques to correctly calculate time, assess tolerances, apply measurements, calculate material requirements and establish quality checks
  • using workplace technology related to the servicing and rectification of faults in lift assisted suspension systems, including the use of specialist tools, measuring equipment, computerised technology and communication devices and the reporting/recording of results

Required knowledge 

A working knowledge of:

  • OH&S and environmental regulations/requirements, equipment, material and personal safety requirements
  • principles of operation relating to various types of hydraulic and pneumatic lift assisted suspension systems
  • construction and operation of major components
  • system testing procedures
  • servicing procedures
  • road-testing techniques
  • fault diagnostic methods and procedures
  • methods of accessing and interpreting manufacturer/ component supplier specification charts

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 is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations in the critical aspects of:

  • observing safety procedures and requirements
  • communicating effectively with others involved or affected by the work
  • selection methods and techniques appropriate to the circumstances
  • completing preparatory activity in a systematic manner
  • completing fault diagnosis and analysis
  • completing servicing and fault rectification procedures to workplace and manufacturer/component supplier requirements
  • completing work within workplace timeframes
  • presentation of equipment to customer in compliance with workplace requirements
  • correctly completing job documentation

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 specified Australian Standards

The following resources should be made available:

  • workplace location or simulated workplace
  • materials relevant to servicing and rectification of faults in lift assisted suspension systems
  • equipment, hand and power tools appropriate to servicing and rectification of faults in lift assisted suspension systems
  • activities covering mandatory task requirements
  • specifications and work instructions

Method of assessment 

Assessment must satisfy the endorsed assessment guidelines of the automotive industry's 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 not only to be satisfied under the particular circumstance, but 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
