Release 1 

New unit of competency.

Application

This unit describes the performance outcomes required to diagnose and repair faults in the engine and transmission management systems of vehicles or machinery. These systems communicate on the vehicle two-wire (CAN-bus) networked controlled circuit, and are an integral part of an engine and transmission management system. The unit 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. Engine and transmission management systems include those in agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

1.4 Hazards associated with the work are identified and risks are managed

1.5 Diagnostic tools and equipment are selected and checked for serviceability

2. Diagnose electronic engine and transmission system

2.1 Diagnostic tests are performed according to workplace procedures and safety requirements  without causing damage to components or system

2.2 Faults are identified from diagnostic test results and causes of faults are determined

2.3 Diagnosis findings and recommendations for necessary repairs or adjustments are reported according to workplace procedures

3. Repair electronic engine and transmission system

3.1 Repair information is sourced and interpreted

3.2 Repair options are analysed and those most appropriate to the circumstances are selected

3.3 Repair tools, equipment and materials are selected and checked

3.4 Repairs and component replacements and adjustments are carried out according to manufacturer specifications, workplace procedures and safety requirements, and without causing damage to components or systems

3.5 Post-repair testing is carried out according to workplace procedures to confirm fault rectification, and any further problems detected as having been introduced during the repair process are rectified

4. Complete work processes

4.1 Final inspection is made to ensure work is to workplace expectations and vehicle or machinery is presented ready for use

4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected

4.3 Tools and equipment are checked and stored and any faulty electrical equipment is identified, tagged and isolated according to workplace procedures

4.4 Workplace documentation is processed according to workplace procedures

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills 

Description 

Learning skills to:

  • identify and locate various sources of information efficiently.

Reading skills to:

  • interpret text, symbols and wiring diagrams in information relating to electrical system testing and repair equipment from manufacturer specifications and workplace instructions and procedures.

Writing skills to:

  • legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used.

Oral communication skills to:

  • clarify instructions
  • report diagnostic findings and make repair recommendations.

Numeracy skills to:

  • match engine and transmission management components and part identification numbers to workplace instructions, vehicle and component part lists, and manufacturer specifications
  • interpret vehicle electrical measurements and readings
  • measure voltage, current and resistance and use basic mathematical operations, including addition and subtraction, to calculate deviations from manufacturer specifications.

Planning and organising skills to:

  • plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.

Technology skills to:

  • use specialised equipment, including multimeters and scan tools.

Range of Conditions

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety requirements  must include:

  • work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for:
  • using specialised tools and equipment
  • using appropriate personal protective equipment (PPE)
  • identifying hazards and controlling risks associated with:
  • working on vehicle high voltage ignition systems
  • wearing jewellery while working around high current wiring systems.

Release 1 

New unit of competency.

Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements and performance criteria, range of conditions and foundation skills:

  • diagnose and repair a fault in the integrated engine and transmission management systems of two different vehicles or machinery, in which the work must involve removing, refitting or replacing a system component that affects the operation of both the engine and the transmission management system.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

  • work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing integrated engine and transmission management systems, including procedures for:
  • using specialised tools and equipment
  • using appropriate personal protective equipment (PPE)
  • identifying hazards and controlling risks associated with:
  • working on vehicle high voltage ignition systems
  • wearing jewellery while working around high current wiring systems
  • integrated engine and transmission management system principles, including:
  • engine and transmission management system topography, inputs and outputs
  • typical vehicle or machinery systems equipped with engine and transmission management systems
  • application, purpose and operation of integrated engine and transmission management systems and components, including:
  • control modules
  • control sensors and actuators
  • communication systems, including controlled area network data bus (CAN-bus)
  • diagnostic testing procedures for integrated engine and transmission management systems, including:

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the integrated engine and transmission management systems that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • workplace instructions
  • manufacturer specifications for engine and transmission management systems
  • two different vehicles or machinery with integrated engine and transmission management system faults
  • diagnostic equipment for integrated engine and transmission management systems, including:
  • multimeter
  • scan tool
  • tools, equipment and materials appropriate for repairing vehicle engine and transmission management systems.
