• Hello, my name is Paul Danner. I am an ASE Ll certified master technician with 20 years of field experience in driveability diagnostics and computer systems troubleshooting.
• For the past 11 years I have been an instructor for Rosedale Technical Institute near Pittsburgh, PA where I developed this book for training my students. Before entering my class students are expected to have a basic understanding of the 4 stroke engine and also some basic electrical background. Although this is important, it is not completely necessary to understand most of the topics and testing methods taught in this book. One of the main focuses in this book is what I like to call the “anti-flowchart”.
• I hate engineer written flow charts! These are step by step procedures that some pencil pusher thinks is the best way to troubleshoot a particular problem on a car. For the most part they don’t give us technicians enough credit. They are certainly never written with speed in mind. How could they be when half of them start off with disconnecting the computer and the sensor and checking the wire for opens and shorts?
• Do they realize that step one could take more than a half hour to just get to the computer? This is ridiculous! There has to be a better way! I think I have said that to myself thousands of times over the past 20 years. Well guess what, I have found a better way and I want to share it with you.
• Some of my methods are a little unorthodox, but if used correctly there is no faster or more accurate method for computer systems trouble shooting than what I have outlined in this book.
• Do I still use engineer written flow charts? Of course, but only as a guide and almost never literally. Maybe someday engineers will wake up and figure out that some of us can handle more information than what they are providing. Until then we must develop a more complete understanding of sensors and circuit designs. Once we have these fundamentals we will be able to troubleshoot ANY computer controlled system, not just a fuel injection computer.
• I even fixed my furnace at home using these same principles!
