Setting up and testing prototype vehicle electrical/electronic engine/transmission control units
Overview
This standard identifies the competences you need to set up, test and adjust electrical/electronic engine/transmission control equipment, in accordance with approved procedures. The equipment and systems to be set up and tested may be on bench or test rig or fitted to the prototype vehicle. You will be required to use appropriate drawings, specifications, and test documentation to set up, test and adjust the various items of equipment. You will be expected to use the specified/appropriate techniques to carry out the setting-up and testing procedures in the correct sequence. The equipment to be set up and tested will include engine management, traction control and gear selection systems.
Your responsibilities will require you to comply with organisational policy and procedures for the setting-up, testing and adjusting activities undertaken, and to report any problems with the activities, components or equipment that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying appropriate setting-up and testing techniques and procedures to prototype vehicle electrical/electronic engine/transmission control systems. You will understand the engine/transmission control systems being set up and tested, and their application, and will know about the testing and adjustment techniques, test equipment and methods, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the system functions to the required specification.
You will understand the safety precautions required when carrying out the setting-up and testing operations. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- follow all relevant setting-up and operating specifications for the product or asset being configured
- set up the equipment following defined procedures and ensuring that all operating parameters are achieved
- deal promptly and effectively with problems within your control and report those that cannot be solved
- check that the configuration is complete and that the equipment operates to specification
ensure that work records are completed, stored securely and available to others, as per organisational requirements
leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements

- how to recognise defects (under or over performance)
- the various fault finding techniques that can be used if the system fails the test
- displaying/recording test results, and the documentation to be used
- how to interpret the test readings obtained, and the significance of the readings gained
- how to analyse the test results
- the authorisation requirements for changes to test procedures
- the importance of ensuring that test equipment is used only for its intended purpose and within its specified range and limits
- potential problems or errors that could occur, and which may affect the test results, and how they can be avoided
- the environmental control and company operating procedures relating to the testing activities
- the documentation required, and the procedures to be followed on completion of the tests
- the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
Scope/range
