Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to test an existing wiring harness and loom, remove, fabricate and fit the new wiring harness and loom, and then test its operation. It involves preparing for the task, performing the work, and completing workplace processes and documentation.It applies to those working in the automotive service and repair industry. The wiring harnesses and looms include those in agricultural machinery, heavy commercial vehicles, light vehicles, vessels, mobile plant machinery, motorcycles or outdoor power equipment.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 the vehicle, vessel or machinery wiring harnesses and looms that they have repaired, 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 workplace or simulated workplace

workplace instructions

manufacturer machinery wiring specifications

three different vehicles, vessels or machinery requiring repairs to their wiring harnesses and looms

tools, equipment and materials appropriate for repairing wiring harnesses and looms, including:

multimeter

continuity tester

crimping tools

soldering equipment
