Automotive Repair Case Studies(Diagnostic Strategies of Modern Automotive Systems)By Mandy ConcepcionIn this section, we'll take a look at automotive diagnostics in action. An effort has been made to look at problems in different ways, in each of the examples. Although there are many ways to perform the same task, the idea here is to show the technician or avid DIY mechanic the different ways to go about diagnosing automobiles. Special attention is given to specific systems and different makes and models. The different real life diagnostic cases are explained from narrated perspective to make learning easier. Hopefully you find this section enlightening and productive. Enjoy your readings.Table of Contents* - Audi data bus signal recognition (exposes the intricacies of diagnosing vehicle networks and how computers talk to each other.)* - Cadi idle re-learn (explains the importance of module re-learn procedure, which is done by re-adapting the ECM to a new sensor.)* - Case of the EVAPs (these emission systems are difficult to diagnose, due to their complexities.)* - Computer Data Lines (scan tools talk to the different engine modules or computers through the data line or bus. See how to diagnose this type of problem.)* - Faulty EGR operation (the EGR is in charge of lowering combustion temperatures. But issue with this system can cause pinging, performance, misfire and countless other issues.)* - Lean (dirty) MAF (the lean condition comprises about 60% of all engine performance issues. Learn to deal with this situation.)* - The case of the low volume (Fuel pumps deliver both pressure and volume. If one of these is missing then the engine has problems.)* - Unsynchronized CAM & CRK signals (CAM and CRK signal synchronization is needed for the engine to start.)* - Wrong MAP reading (The manifold air pressure is a main input to the ECM. See how this sensor creates havoc with the engine.)* - The Cadi's dual crank affair (this Cadillac's engine control system has dual crank sensors. Learn to diagnose these systems.)* - Analytical misfire code (Misfires are difficult to diagnose and this case shows precisely that.)* - The misfire ghost (A case of hard to find misfire.)

See the entire diagnostic path and also using an array of auto diagnostic equipment. Find out what happened next... * - Nissan Altima's Cross Identity Crisis That's right, a Nissan with what you could call double personality. See how an ingenuous auto repair and diagnostic path was used to get to the issue. Shown with dedicated diagrams and animations to prove the case and present the case to you. Also get the scoop on using the Fox and Hound for electrical diagnostics. * - Nissan Maxima's Burning Bush A surging idle speed issue with a difficult to detect origin. After replacing various parts, the shop ran out of options and called in the expert. See hoe this popular stepper-motor component was inoperable and the diagnostic path to repair. Follow this case from a simple scan to deep ECM diagnostics using various equipment. * - Nissan that Wouldn't Cool Down Yes, a hot Nissan, but to the engine, the climate control system. That's right, this A/C compressor did not want to turn ON, no matter what and it was fully computerized. The auto diagnostic path was not as easy as one would think. In fact this issue proved a high tech diagnostic and tough to detect. see what happened... * - Noisy Neighbor An erratic engine on a Ford Explorer where the TPS and ECM had already been replaced. What could it be? See the whole auto repair path and learn to interpret scan PID graphs, scope waveforms and analyze wiring issue. Get the whole story here... * - BONUS - The AFR or air fuel ratio sensor circuit The newer wide band or A F R O2 sensor solves the narrow sensing problem of the previous Zirconium sensors. These sensors are often called by different names. Learn how they work and how to test them.

Oil Spill Environmental Forensics Case Studies includes 34 chapters that serve to present various aspects of environmental forensics in relation to “real-world oil spill case studies from around the globe. Authors representing academic, government, and private researcher groups from 14 countries bring a diverse and global perspective to this volume. Oil Spill Environmental Forensics Case Studies addresses releases of natural gas/methane, automotive gasoline and other petroleum fuels, lubricants, vegetable oils, paraffin waxes, bitumen, manufactured gas plant residues, urban runoff, and, of course, crude oil, the latter ranging from light Bakken shale oil to heavy Canadian oil sands oil. New challenges surrounding forensic investigations of stray gas in the shallow subsurface, volatiles in air, dissolved chemicals in water (including passive samplers), and biological tissues associated with oil spills are included, as are the effects and long-term oil weathering, long-term monitoring in urbanized and non-urbanized environments, fate and transport, forensic historical research, new analytical and chemical data processing and interpretation methods. Presents cases in each chapter on the application of specific oil spill environmental forensic techniques Features chapters written by international experts from both academia and industry Includes relevant concepts and theories elucidated for each theme

Diagnostics, or fault finding, is a fundamental part of an automotive technician's work, and as automotive systems become increasingly complex there is a greater need for good diagnostic skills. Advanced Automotive Fault Diagnosis is the only book to treat automotive diagnostics as a science rather than a check-list procedure. Each chapter includes basic principles and examples of a vehicle system followed by the appropriate diagnostic techniques, complete with useful diagrams, flow charts, case studies and self-assessment questions. The book will help new students develop diagnostic skills and help experienced technicians improve even further. This new edition is fully updated to the latest technological developments. Two new chapters have been added – On-board diagnostics and Oscilloscope diagnostics – and the coverage has been matched to the latest curricula of motor vehicle qualifications, including: IMI and C&G Technical Certificates and NVQs; Level 4 diagnostic units; BTEC National and Higher National qualifications from Edexcel; International Motor Vehicle qualifications such as C&G 3905; and ASE certification in the USA.
