What an assessment for MEM27002 must cover

37 assessable components: 3 elements (16 performance criteria), 10 performance evidence and 11 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Determine job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from specifications, drawings, job sheets or work instructions

2 Assess fuel system operation

2.1Apply knowledge of fuel injection principles and component part functions/operation to assess fuel system operation
2.2Start, operate and shut down diesel plant/equipment
2.3Undertake checks safely to prescribed procedures
2.4Determine and record flows, pressures and speeds
2.5Interpret engine and plant operating characteristics and parameters
2.6Interpret test results and operational data for faults and serviceability

3 Repair compression ignition system

3.1Identify components to be repaired or replaced
3.2Select appropriate tools, equipment and materials
3.3Repair and replace components according to manufacturer specifications, WHS and environmental requirements
3.4Time the high-pressure fuel pump or injectors to engine
3.5Use test equipment to test ignition system and set to specifications
3.6Record repair according to workplace procedures

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
describing the function and operation of ignition system component parts through identification and interpretation of appropriate specifications, charts, lists, drawings, service documents and reference to fuel injection principles
starting/operating and shutting down diesel plant/equipment
conducting operational checks of the diesel fuel system in determining and recording fuel flows, pressures and engine speeds using appropriate test equipment in accordance with specifications and procedures
interpreting faults from the test results and ignition system operating characteristics and parameters
determining serviceability of the fuel system components, including: engine control unit (ECU), injectors, sensors
removing, replacing and carrying out adjustment of ignition system components, including: injectors, sensors, connectors and cables, tank, filters, fuel pumps
undertaking calculations and numerical operations for testing compression ignition fuel systems
timing the high-pressure fuel pump or injectors and carrying out final adjustments to engine in accordance with specifications
recording/reporting service activities according to SOPs.

Knowledge evidence

safe work practices and procedures and use of personal protective equipment (PPE)
principles of fuel injection and function/operation of each component in a fuel injection system
types of fuels used in compression engines, air/fuel ratios, combustion process and combustion products
compression ignition management systems, including: electronic injectors, electronic control systems, common rail systems, exhaust management and treatment
procedures for starting up, operating and shutting down diesel plant and equipment
visual and aural checks to be made on the diesel fuel system and procedures for carrying out these checks
use of appropriate test equipment, including use of oscilloscopes, multimeters and other electrical and electronic test equipment and methods for testing: high and low pressure fuel pump performance, oil pressures, injectors, sensors and circuits, exhaust composition, engine performance against specifications
plant operating characteristics and parameters
indicators of ignition system faults, including: engine knock, difficulty in starting, incomplete combustion and excessive smoke, warning lights and diagnostic trouble codes
causes of ignition system faults, including: dirty/worn injectors, incorrect timing, poor fuel, poor oil, low compression, worn engine components e.g. piston rings, incorrect timing, damaged dirty air, fuel and oil filters
reasons for the decisions made with respect to serviceability and likely faults and causes for unserviceable systems.

Questions about assessing MEM27002

What does an assessment tool for MEM27002 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM27002 needs to address all 37 unit components: 3 elements with 16 performance criteria, 10 performance evidence requirements, 11 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM27002?

Auditori pulls the current release of MEM27002 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM27002 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM27002 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM27002, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
