Application
This unit describes the performance outcomes required to remove, replace and program electrical and electronic units and assemblies integral to vehicle and machinery controller area network databus (CAN-bus). Electrical and electronic units and assemblies include powertrain control modules, engine and body control modules, and other electronic control modules that may require manufacturer programming procedures.
It applies to those working in the automotive service and repair industry. The electrical and electronic units and assemblies include those fitted to 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.

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 the electrical and electronic units and assemblies they have removed, replaced and programmed, 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 electrical and electronic unit and assembly specifications
two different vehicles or machinery requiring removal, replacement and programming of electrical and electronic units and assemblies
tools, equipment and materials appropriate for removing, replacing and programming electrical and electronic units and assemblies, including scan tool.
