Application
This unit describes the skills and knowledge required to diagnose and repair faults in electronically controlled suspension 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. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.
This unit applies to those working within the automotive service and repair industry. The electronically controlled suspension systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, mobile plant machinery or motorcycles.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
