Unit Descriptor

Unit descriptor 

This unit describes the performance outcomes required to install and test basic vehicle ancillary electrical components that do not require programming procedures to connect and interface them with the vehicle computer area network databus (CAN-bus) network.

The unit also involves identifying and confirming work requirements, preparing for work, and completing work finalisation processes, including clean-up and documentation.

Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.

Application of the Unit

Application of the unit 

Work applies to the installation and testing of basic ancillary electrical components that are fitted in light and heavy vehicle, mining, construction, agricultural, motorcycle, outdoor power equipment and marine environments.

Basic ancillary electrical components include driver interlocks; remote keyless entry and security alarm systems; audio systems; mobile phones; speed alert and navigation systems; reverse parking aids, including audible alerts and cameras; and driver gauges and instruments.

Work requires individuals to demonstrate some judgement and problem-solving skills in managing own work activities and contributing to a productive team environment.
