Page 2 of 5 Suitable tools and equipment means industry approved tools and equipment that are recognised within the industry as being the most suited to complete the task in a professional and competent manner with due regard to safe working practices. 3 This unit standard includes either computer controlled electronic ignition systems or standard (stand-alone) electronic ignition systems used on motorcycle engines. 4 Personal injury or injury to others could result from the high voltages generated by electronic ignition systems. 5 For this unit standard, it is essential that the practical assessment evidence is obtained in the workplace under normal workplace conditions. Elements and performance criteria Element 1 Diagnose faults in an electronic ignition system on a motorcycle engine. 1.1 Safe working practices are observed throughout the task in accordance with 1.2 Suitable equipment is selected and used to enable the system to be tested in 1.3 Self-diagnostic test codes are activated, read, and interpreted, to identify any circuit that has a fault, in 1.4 The circuit indicated by the self-diagnostic test codes is tested, and the fault is located and identified in 1.5 No damage to circuit components and electronic devices is caused by using test instruments. 1.6 The battery is tested for cranking voltage, and the result noted, in accordance with service information. 1.7 A check is made to determine if the triggering device turns when the engine is cranked, and the result noted, in 1.8 A test is made to determine whether the ignition cables and leads are connected correctly, and if high tension (HT) is present at a spark plug and at the ignition coil when cranking, and the results noted, in accordance with service information.
Page 3 of 5 1.9 Tests are made to determine the presence of the appropriate low tension (LT) signal at the ignition coil with key on, engine off (KOEO) and with the engine being cranked, and the results noted, in signal absent, steady, pulsing. 1.10 The initial ignition timing is checked with a timing light, and the result noted, in 1.11 The results of all tests are analysed, and any faults and their probable causes are identified in Element 2 Test electronic ignition system components for faults. 2.1 Safe working practices are observed throughout the task in accordance with 2.2 Suitable equipment is selected and used to enable the components to be tested in 2.3 The HT components are tested for serviceability, and any faults identified and noted, in HT leads, ignition coil, spark plugs. 2.4 The rotor and distributor are checked, and any faults identified and noted, in shaft and bush wear, operation of automatic advance mechanisms. 2.5 Sensors and actuators are tested in 2.6 The pulse coil is tested, and any faults identified and noted, in accordance with service information. 2.7 The rotor air gap is checked in 2.8 All ignition system ground connections are tested, and the state of their conductivity noted, in

Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards. Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.
Page 5 of 5 Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
