  • 2.2. Meters/gauges/measuring equipment is applied to isolate fault
  • 2.3. Identification of fault(s) are made from test results
  • 2.4. Findings are confirmed by an alternate route/plan
  • 2.5. Faults are diagnosed without causing damage to workplace property, component or equipment
  • 2.6. Inspections are carried out according to industry regulations/guidelines, WHS legislation, legislation and enterprise procedures/policies
3. Recommend rectification method(s)
  • 3.1. Report of findings is completed in workplace approved format
  • 3.2. Rectification strategy is identified
  • 3.3. Consequences of ignoring strategy are identified
  • 3.4. Any faults in conflict with roadworthiness or safe operation of component/equipment are immediately brought to the attention of the supervisor for action
4. Component/equipment is prepared for customer use
  • 4.1. Work schedule documentation is completed
  • 4.2. Final inspection is made to ensure safety features are in place
  • 4.3. Final inspection is made to ensure work is to workplace expectations
  • 4.4. Job card is completed and delivered to appropriate persons
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Diagnose problems
Diagnosis is a process of elimination, fault find and fault isolation
Diagnostic methods
Diagnostic methods are to include:
removal and replacement, dismantling, adjusting
visual and aural identification and testing
component/equipment performance comparison
on-and off-site, indoor and outdoor and on-and off-shore diagnosis
WHS
WHS requirements are to be in accordance with legislation/regulations/codes of practice and enterprise safety policies and procedures. This may include protective clothing and equipment, use of tooling and equipment, workplace environment and safety, handling of material, use of fire fighting equipment, enterprise first aid, hazard control and hazardous materials and substances
Personal protective equipment
Personal protective equipment is to include that prescribed under legislation/regulation/codes of practice and workplace policies and practices
Safe operating procedures
Safe operating procedures are to include, but are not limited to operational risk assessment and treatments associated with vehicular movement, toxic substances, electrical safety, machinery movement and operation, manual and mechanical lifting and shifting, working in proximity to others and site visitors
Emergency procedures
Emergency procedures related to this unit are to include but may not be limited to emergency shutdown and stopping of equipment, extinguishing fires, enterprise first aid requirements and site evacuation
Environmental requirements
Environmental requirements are to include but are not limited to waste management, noise, dust and clean-up management
Quality requirements
Quality requirements are to include, but are not limited to regulations, including Australian Standards, internal company quality policy and standards and enterprise operations and procedures
Statutory/regulatory authorities
Statutory/regulatory authorities may include Federal, State/Territory and local authorities administering acts, regulations and codes of practice
Tooling and equipment
Tooling and equipment may include computer software, computer hardware, specific tooling and equipment used for dismantling, testing and diagnosis, meters, gauges and measuring equipment
Materials
Materials may include minor spare parts and consumables and cleaning materials
Communications
Communications are to include, but are not limited to verbal and visual instructions and fault documenting and may include site specific instructions, written instructions, plans or instructions related to job/task, telephones and pagers
Information/documents
Sources of information/documents may include:
verbal or written and graphical instructions, signage, work schedules/plans/specifications, work bulletins, memos, material safety data sheets, diagrams or sketches
safe work procedures related to the diagnosis of faults
regulatory/legislative requirements pertaining to automotive industry, including Australian Design Rules, Environment Protection Regulations (Diesel Fuels) and National Environment Protection For Diesel Vehicle Guidelines
engineer's design specifications and instructions
organisation work specifications and requirements
instructions issued by authorised enterprise or external persons
Australian Standards
EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations in the critical aspects of:
observing safety procedures and requirements
communicating effectively with others involved in or affected by the work
selecting methods and techniques appropriate to the circumstances
completing preparatory activity in a systematic manner
conducting diagnosis of a range of faults in accordance with workplace requirements to test and verify symptoms
interpret results
confirm diagnosis of fault(s)
diagnosis carried out to manufacturer/component supplier requirements
complete diagnosis within workplace timeframes
component/equipment presentation to customer in compliance with workplace requirements
Context of, and specific resources for assessment
Application of competence is to be assessed in the workplace or simulated worksite
Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints
Assessment is to comply with regulatory requirements, including Australian Standards
The following resources should be made available:
workplace location or simulated workplace
material relevant to diagnosis of faults
equipment, hand and power tooling appropriate to the diagnosis of faults
activities covering mandatory task requirements
specifications and work instructions
Method of assessment
Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R Training Package
Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge
Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies
Assessment may be applied under project related conditions and require evidence of process
Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
