Assessment tool
Version 1.0 Issue Date: May 2024
This unit describes the performance outcomes required to diagnose and repair faults in the electronic compression ignition engine management systems of vehicles 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.
It applies to those working in an automotive service and repair industry. Compression ignition engine 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.
