This document contains general information, Test Specifications, Task Lists, sample questions, and test preparation resources for these ASE tests.  \nThe following tests are covered by this guide:  \n∙ Gasoline Engines (T1)  \n∙ Diesel Engines (T2) *  \n∙ Drive Train (T3) *  \n∙ Brakes (T4) *  \n∙ Suspension and Steering (T5)*  \n∙ Electrial/Electronic Systems (T6) *  \n∙ Heating, Ventilation, and Air Conditioning (HVAC) Systems (T7)*  \n∙ Preventive Maintenance Inspection (PMI) (T8) *  \n* Required for recognition as an ASE Certified Master Medium/Heavy Truck Technician  \nThe Test Specifications in this study guide are determined by working professionals and technical experts and list the main content covered by each test and the number of test questions devoted to each topic  .  \nThe Task Lists are developed by working professionals and technical experts, and they spell out the technical knowledge and skills required for success on the test. The Task List provides a valuable  \nchecklist of what you should know. Every question on the test represents one or more of these tasks, although some tasks may not appear on the version of the test that you see. To improve changes of success, use the Task List to identify weak areas and to select learning resources  .  \nThe sample questions show the several types of multiple-choice question formats used on an actual ASE test. Some questions have special instructions; those same instructions will appear with similar questions on the ASE tests. If you are a native Spanish speaker, be aware that all ASE tests have a pop-up English to Spanish glossary .  \nASE Certification requires successful completion of the test and documentation of relevant work experience (2 years for tets in this series) .
