Elements and Performance Criteria
- Prepare for diagnostic procedure
- Nature and scope of the work requirements are identified and confirmed.
- OH&S requirements, including individual State/Territory regulatory requirements and personal protection needs are observed throughout the work.
- Technical and/or calibration requirements for testing and diagnosis are sourced and support equipment is identified and prepared.
- Analyse reported faults
- Information is gathered from all sources to provide a full overview of all faults and conditions under which they occur.
- Function and operation of the system when operating correctly are identified.
- Systematic fault-finding processes are used across relevant systems to determine the extent of the fault.
- Additional technical sources are consulted to assist with analysis, if necessary.
- Actual faults are distinguished from perceived faults.
- Identify causes of faults
- Diagnostic equipment and tests are selected to facilitate precise identification of faults and causes.
- Tests are applied systematically and efficiently to gather precise data on system operation.
- Appropriate use is made of technical information to compare gathered data with specifications.
- Test results and gathered data are compared to system specifications and normal functions, and discrepancies are identified.
- Source/cause of fault is isolated and confirmed.
- Establish repair requirements
- Viability of repair or replacement is assessed.
- Appropriate repair procedures are identified and prescribed to meet customer service requirements.
- Repair requirements are clearly and legibly documented and/or communicated to appropriate persons.
- Repairs involving equipment/skills not held in the workshop are sourced from specialist workshops.
- Customer is informed of the diagnosis and repair requirements.
