Description
This unit describes the skills and knowledge required to diagnose complex faults in heavy commercial vehicle transmission and driveline systems and determine the repair action necessary to restore system performance. It involves confirming the existence of a fault, developing a diagnostic testing strategy, diagnosing the cause of the fault, reporting conclusions and making repair recommendations. Complex faults are outside the normal scope of a technician’s diagnosis and repair work. They include intermittent faults, multi-system faults, faults introduced as a result of system repairs, and indirect faults caused by the influence of external systems, requiring the application of complex diagnostic processes to resolve.The unit applies to those who work in the automotive service and repair industry. The heavy commercial vehicle transmission and driveline systems include those of trucks or buses.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
