This unit describes the skills and knowledge required to diagnose and repair electronic body management systems. These systems include two-wire high and low speed (CAN-bus) and single wire low speed (LIN-bus) networked circuits in the vehicle or machinery’s embedded network electronic control system and are essential to controlling vehicle, vessel or machinery body control functions, including passenger convenience, comfort, navigation and infotainment systems. 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 electronic body management systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, or mobile plant machinery.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
