How to Use The Snap-On MODIS With the ever increasing electronic content in today's vehicles, the scan tool has become the tool of choice to look into the ECM or module func-tions. The scanner is the only window into what the different modules are doing. One thing's to use an oscilloscope or GMM, but to know what the computer is actually interpreting, your only choice is this piece of equip-ment. This book is different than other book on the MODIS. This book actually teaches you how to use the equipment and interpret the PID datastream. This book also borrows from some of our other...

Automotive Relay Circuit Guide (Includes circuit explanations, how current flows and how to wire relays from the ground up.) By Mandy Concepcion This book is a comprehensive work on automotive relays and their circuit analysis. The book is also a companion to our Video-DVD series of the same title. Here, we analyze how automotive relays are connected with their peripheral components. Each section starts with the specifics of the components used in that circuit and then there's a deep analysis of how current flows on the circuit. The idea is to first explain and give the reader the particulars...
