Application

This unit describes the skills and knowledge required to diagnose and repair electronically controlled steering systems. These systems include two-wire high and low speed (CAN-bus) and single wire low speed (LIN-bus) networked circuits in the embedded network electronic control system of a vehicle or machinery. 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 electronically controlled steering systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, motorcycles 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 of competency includes third-party evidence, individuals must provide evidence that links them to the electronically controlled steering 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 specifications for electronically controlled steering systems
  • two different vehicles or machinery with faults in the electronically controlled steering system components specified in the performance evidence
  • diagnostic equipment for electronically steering controlled system, including:
  • multimeter
  • scan tool
  • tools, equipment and materials appropriate for repairing the electronically controlled steering systems of vehicle and machinery.
