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. |
Failure analysis and evaluation process | The objective of the failure analysis and evaluation process may be to determine fault rectification measures, to effect variation in system characteristics and parameters or to enhance system performance. |
Vehicles | Light vehicles are to include two-wheel and four-wheel drive vehicles. |
Steering systems | Steering systems to be covered in this unit are to include mechanical and power. |
Steering failures | Light vehicle steering failures covered by this unit are to include tyre wear, driveability, vibration, directional stability, tracking, calibration/adjustment specifications, component specifications, component assembly, component damage and system modifications. |
Suspension systems | Suspension systems are to cover coil, spring and spring leaf types. |
Suspension system failures | Light vehicle suspension system failures covered by this unit are to include erratic steering, mechanical damage, sub-frame alignment, component damage and systems modifications. |
Unit context | WHS, vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures. Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements. Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults. |
Evaluation criteria | Evaluative criteria, sometimes referred to as success factors, detail the criteria against which the achievement of the objectives of the analysis are judged. They are to include statistically based criteria and may include other measures. |
Isolation procedures | Equipment isolation procedures are to industry and enterprise standards. |
Testing equipment | Testing equipment is to include tape measure, tyre pressure gauge, string line, adjustable electronic bubble level and may include laser wheel alignment system. |
Tests | Tests to be conducted are to include ball-joint wear, camber, castor, leveller operation pitman arm specifications, ride height, steering access inclination, steering linkage specification, sub-frame alignment, thrust line, toe-in, toe-out turns, turning radius left/right, tyre pressures, tyre tread and wheel bearing specification. |
Personal protective equipment | Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices. |
Information and procedures | Workplace procedures relating to the use of tooling and equipment. Workplace procedures relating to reporting and communication. Manufacturer/component supplier specifications and application procedures for testing equipment and material. Manufacturer/component supplier specifications, schematics and operational procedures related to light vehicle steering and suspension systems. Australian design rules. Vehicle industry regulations. Vehicle industry publications related to emerging steering and suspension system technology and technology changes. |
