Proper and timely maintenance of automobiles will save time and money. Mechanical symptoms can be caused by a multitude of failures that can be difficult to isolate. Proper diagnostic tools and equipment are necessary to service advanced automotive systems. A problem solver understands what has been done, knows why the process was appropriate, and can support it with reasons and evidence. Supporting rapidly advancing automotive technologies will require ongoing education and certification. Challenges faced by the automotive industry reflect global, social and environmental changes. Individual and company ethical practices directly affect reputation and the ability to be competitive in the marketplace. An individual s earning potential is directly related to that individual s skill level, certifications, and continuing education. LEARNING STRAND Automotive Systems Diagnostics Page 2 of 11
