Application
This unit describes the performance outcomes required to remove and replace electrical units and assemblies. Electrical units and assemblies include headlights, tail-lights, and vehicle and machinery control modules that do not require programming procedures on replacement. These electrical units and assemblies are not connected to vehicle controller area network databus (CAN-bus) topography.
It applies to those working in the automotive service and repair industry. The electrical units and assemblies include those fitted to agricultural machinery, heavy commercial vehicles, light vehicles, vessels, motorcycles, mobile plant machinery or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements, performance criteria, range of conditions and foundation skills:
remove and replace two of the following systems on the non controller area network databus (CAN-bus) circuits of two different vehicles or machinery:
headlight or tail-light assembly
windscreen washer and wiper motor assembly
door and window motor assembly
central door locking system
electric mirror assembly
electric brake controllers.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to removing and replacing electrical units and assemblies, including procedures for identifying hazards and controlling risks associated with:
working with vehicle ignition systems with injector high voltages
wearing jewellery while working around high current wiring systems
procedures for removing, replacing, and testing electrical units and assemblies, including procedures for adjusting and calibrating systems and components
key features of basic non CAN-bus networked electrical units and assemblies, including:
headlight assemblies
tail-light assemblies
side and rear vision mirrors
windscreen washer and wiper motor assemblies
door and window motor assemblies
central door locking systems
electric brake controllers
types of wiring systems found in vehicles, including:
basic wiring
twisted pair
shielded wiring
CAN-bus wiring
options for diagnosing faults, including:
continuity testing
insulation testing
isolating possible faults
replacing blown fuses or circuit breakers
replacing damaged connectors or terminals
visually inspecting and evaluating components
location and content of technical information, wiring diagrams and graphic symbols relating to electrical units and assemblies
procedures for testing electrical systems, including:
accessing electrical terminals and using test probes without damaging connectors, fuse holders and wiring
checking resistance, current flow and voltage drop of system circuits.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
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 having removed and replace electrical units and assemblies in vehicles or machinery, 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 workshop or simulated workplace
workplace instructions
manufacturer specifications relating to removing and replacing electrical units and assemblies
two different vehicles or machinery with faults in their electrical systems
tools and electrical test equipment appropriate for diagnosing electrical units and assemblies.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.
Skills | Description |
Learning skills to: | locate appropriate sources of information efficiently. |
Reading skills to: | interpret text, symbols and diagrams in manufacturer specifications, safe operating procedures, and other workplace information. |
Writing skills to: | legibly and accurately fill out workplace documentation relating to removing and replacing electrical units and assemblies. |
Oral communication skills to: | clarify instructions. |
Numeracy skills to: | match component part numbers to workplace instructions and vehicle and component part lists interpret measurements of voltage, current and resistance relating to electrical units and assemblies measure materials and components to determine compliance with manufacturer specifications. |
Planning and organising skills to: | plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes. |
Technology skills to: | use specialised testing equipment, such as multimeters. |
Range Statement
