Application
This unit describes the skills and knowledge required to diagnose and repair electric braking systems. These systems are single wire (non CAN-bus) circuits and include electric braking systems in light vehicles and machinery fitted with electric trailer braking controllers or trailers fitted with electric brakes. The systems used vary based on the work context. The unit involves preparing for the task, sourcing a diagnostic testing strategy, diagnosing the cause of the fault, carrying out the repair, performing post-repair testing, and completing workplace processes and documentation.
The unit applies to those who work in the automotive service and repair industry. The electric braking systems include those in agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessment Conditions
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 includes third-party evidence, individuals must provide evidence that links them to the electric braking systems that they have worked on, 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 electric braking system specifications
- two different vehicles or machinery with electric braking system faults
- diagnostic equipment for electric braking systems, including scan tool
- tools, equipment and materials appropriate for repairing vehicle and machinery electric braking systems.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
