In How to Diagnose and Repair Automotive Electrical Systems, author and ASE Certified Master Technician Tracy Martin explains the principles behind automotive electrical systems and describes how they work.

Automotive electrical systems can seem a mystery, if not a black art, to the weekend mechanic and even to some experienced pros. From Ohm’s Law, and an explanation of 12-volt systems, to specific electrical scenarios and more, Tracy thoroughly dissects automotive electrical systems and explains the various tools needed for diagnoses and repair including: multimeters, voltmeters, timing lights, coil testers, lab scopes, and more.

How to Use Automotive

Diagnostic Scanners

Paying a dealership to scan for trouble codes to determine why your car's "check engine" light has come on is a common expense. Scanning automotive computers for trouble codes at home can save you money and only requires the ability to plug in an adapter to an easily accessible port on your car and interface with a smartphone or tablet. With the right devices, and a little knowledge, it is possible to perform On Board Diagnostic checks in your garage or driveway.

How to Use Automotive Diagnostic Scanners (second edition) teaches you how to choose the right scanner for your application; how to use it and provides a comprehensive list of trouble code definitions. Photos and diagrams help you understand OBD-I and OBD-II systems (including CAN) and the scanners that read the information they record. From catalytic converters, and O2 sensors, to emissions and automotive detective work, this is the complete reference for keeping your vehicle EPA-compliant and on the road.
