Unit Descriptor
Unit descriptor |
This unit describes the performance outcomes required to diagnose complex faults in heavy commercial vehicle transmission and driveline systems in order to initiate action to service, repair, replace or improve performance. The unit involves evaluating system performance and identifying possible operational anomalies. Faults may be electrical, electronic, mechanical or hydraulic by nature, requiring the application of complex diagnostic processes to resolve. Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority. |
Application of the Unit
Application of the unit |

Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Identify and confirm the work requirement |
1.1. Workplace instructions and reports are used to determine the nature and objective of system diagnosis requirements 1.2. Specifications for correctly functioning heavy commercial vehicle transmission and driveline systems are accessed and interpreted 1.3. Workplace health and safety (WHS) requirements , including equipment and system isolation and personal protection needs, are observed and addressed throughout the work 1.4. Effects of systemic deficiencies or discrepancies or faults in heavy commercial vehicle transmission and driveline systems are identified and confirmed from indirect or direct evidence 1.5. Possible safety impacts of the work are considered and responded to according to regulatory and workplace procedures |
2. Prepare to perform diagnosis |
2.1. Criteria for diagnosis are developed and adopted to meet the objective of the work 2.2. System performance achievements or discrepancies are identified from scrutiny of technical support information and available on-board diagnostic systems 2.3. Diagnostic methods, including complexity of diagnostic process, sequence, tests and testing process are identified and selected from the range of available options 2.4. Testing equipment is obtained and prepared for application according to manufacturer, component supplier and workplace requirements 2.5. Tools and materials required to support the diagnostic process are identified, selected and prepared for use |
3. Apply complex diagnostic process |
3.1. Selected diagnostic processes are followed according to specifications and workplace procedures 3.2. Testing is carried out according to workplace procedures and manufacturer and component supplier specifications 3.3. Findings are verified, if necessary, by using reliable alternate or optional processes 3.4. Conclusions are drawn from findings and documented according to workplace requirements 3.5. Information and detail related to the evaluation of diagnosis is provided to the appropriate person or customer to confirm further action to be taken |

|
Context of, and specific resources for assessment |
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting. Assessment is to occur:
Assessment is to comply with relevant:
The following resources must be made available for the assessment of this unit:
|
Method of assessment |
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge. Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application. Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients. Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed |
