EVIDENCE GUIDE 

Underpinning skills 

These include a number of processes that are learnt 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 questions below highlight how these processes are applied in this 
competency unit. The number in brackets indicates the level to which the key competency 
needs to be demonstrated where (1) is where work is within set conditions and process, (2) is 
where the management or facilitation of conditions or process is exercised, and (3) is where 
the design and/or development of conditions or process are required. 

How will the candidate apply the following key competency in this unit?

Collect, analyse and 
organise information 

 

Collect, organise and understand legal and technical 
information related to contemporary automotive electrical 
systems modifications. 

 (Level 2)

Communicate ideas and 
information 

 

Communicate ideas and information to enable confirmation of 
work requirements and specifications, coordination of work 
with site supervisor, other workers and customers, the reporting 
of work outcomes and the completion of regulatory, 
commercial and vehicle information systems inputs. 

(Level 2)

Plan and organise 
activities 

 

Plan and organise activities including the development and 
planning of modification processes, the preparation and layout 
of the worksite and the obtaining of tools, equipment, material 
and testing equipment to avoid any back tracking, workflow 
interruptions or wastage. 

(Level 3)

Work with others and in 
a team

(Level 2)

 

EVIDENCE GUIDE 

Resource implications 

• 

Access to operational electrical systems requiring 
modification, testing equipment as stipulated in the 
Range Statement, technical information and a realistic 
work environment 

Method of assessment 

• 

Assessment of this competency is most likely to be 
project related and require portfolios or other forms of 
indirect evidence of process. Direct evidence will 
include certification of compliance of the final 
outcome/product or authorisation for use by a competent 
authority 

• 

Assessment must confirm the inference that competency 
is able not only to be satisfied under the particular 
circumstances, but is able to be transferred to other 
projects 

Context/s of assessment 

• 

Assessment may occur on the job or in a workplace 
simulated facility with relevant process equipment, 
material, work instructions and deadlines

RANGE STATEMENT  

The Range Statement provides advice to interpret the scope and context of this unit of 
competency, allowing for differences between enterprises and workplaces. It relates to the unit 
as a whole and facilitates holistic assessment. The following variables may be present for this 
particular unit: 

Unit scope 

•  Electronic modifications to be covered by this unit may 

include computer controlled systems where the process 
relates to three categories: 

1.  Modification that is carried out external to the 

computer, utilising “off the shelf” components and 
modification to wiring circuitry 

Example 

 

Modification to an electronic engine management 
system, improving the performance of an ECU 
controlled engine cooling fan system that necessitates 
changes to relay circuitry. 

2.  Modification that is carried out external to the 

computer, utilising electronic circuit design, 
development, manufacture, trial, evaluation, 
improvement, and commissioning 

Example 

 

Development of an electronic control unit to delay 
engine crank whilst sounding an alarm warning of 
impending start of hazardous equipment.  

3.  Modification that is carried out internally in the 

computer, utilizing electronic circuit design, 
reprogramming, development, manufacture, trial, 
evaluation, improvement, and commissioning 

Examples are 

 

Rectification of an original internal computer 
design/operating deficiency 

 

Modification to an electronic engine management 
computer, to enhance the performance of an engine  

 

Modification to a computerised system, to disable a 
function no longer required by customer 

•  Inputs to the modification method and processes may be 

obtained from customer requirements, manufacturer/ 
component supplier specifications, outcomes of diagnostic 
processes or from regulatory, licensing, intellectual 
property legislation, safety requirements and Australian 
Design Rules
