Elements and Performance Criteria

A complex system is defined as one which integrates two or more automotive systems, or incorporates three or more of mechanical, hydraulic, pneumatic, electrical or electronic media. Examples include hydraulically/ electronically controlled automatic transmissions, anti-lock braking systems, engine management systems integrating ignition, fuel and transmission control systems
Workplace example:
Customer reports intermittent shifting into top gear on an electronically controlled automatic transmission. The customer is asked a number of questions about the conditions in which the problem occurs (e.g. frequency of the problem, speed, road conditions). A road test is conducted, and the technician detects intermittent speedometer operation. After testing of electrical connections, components and sensors, the intermittent speedometer operation is confirmed to be the problem. Repair requirements are determined to be securing the connections on the speedometer wiring
The unit of competence should be contextualised to the qualification it is being applied
Diagnostic methods are to include:
questioning of customer
road testing
hydraulic testing (e.g. performance testing of power steering systems)
electrical testing (e.g. performance testing of engine starting systems)
electronic testing (e.g. electronic interface diagnostic equipment)
mechanical testing (e.g. compression testing on engines)
chemical testing (e.g. testing of cooling systems)
technical/service manuals
component/equipment service history
body measurements

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
analysing faults in complex systems, identifying the cause(s) of faults and establishing repair requirements within an established timeframe for faults incorporating at least three of the following single systems: mechanical, hydraulic, pneumatic and electrical/electronic

Relationship to other units
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role

Underpinning knowledge

A working knowledge of:

OH&S regulations/requirements, equipment, material and personal safety requirements
function and operation of the appropriate complex automotive systems
symptom and cause differentiation
diagnostic procedures and problem-solving techniques
test procedures and test instrument application
documenting and reporting procedures
repair procedures
enterprise quality procedures
work organisation and planning processes

Specific key competencies, underpinning and employability skills required to achieve the performance criteria
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The details below highlight how these competencies are to be applied in the attainment of this unit.

Application of the key competencies in this unit are to satisfy the nominated level in which:

Level 1 - relates to working effectively within set conditions and processes;
Level 2 - relates to management or facilitation of conditions or processes; and
Level 3 - relates to design, development and evaluation of conditions or process.
How will the candidate apply the following key competency in this unit? The candidate will need to:

Collect, analyse and organise information
Apply research and interpretive skills sufficient to locate, interpret and apply manufacturer/component supplier procedures, workplace policies and procedures
Apply analytical skills required for identification and analysis of technical information
(Level 2)

Communicate ideas and information
Apply plain English literacy and communication skills in relation to dealing with customers and team members
Apply questioning and active listening skills for example when obtaining information from customers
Apply oral communication skills sufficient to convey information and concepts to customers
(Level 1)

Plan and organise activities
Apply planning and organising skills to own work activities, including making good use of time and resources, sorting out priorities and monitoring own performance
(Level 2)

Work with others and in a team
Interact effectively with other persons both on a one-to-one basis and in groups, including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal
(Level 1)

Solve problems
The capacity to apply problem-solving strategies in purposeful ways, both in situations where the problem and desired solution are clearly evident and in situations requiring critical thinking and a creative approach to achieve an outcome
(Level 2)

Use mathematical ideas and techniques
Use mathematical ideas and techniques to calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks
(Level 2)

Use workplace technology related to the diagnosis of complex system faults, including the use of measuring equipment, computerised technology and electronics, communication devices and reporting/documenting of results
(Level 2)

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

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 (real or simulated) 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 assessment reflects a process rather than an event and occurs over a period of time to cover the varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other appropriate persons subject to agreed authentication arrangements
