ASE L-1 Preparation Guide

This well illustrated and easy to use guide provides all the necessary information to pass the ASE (National Institute for Automotive Service Excellence) L1 test on advanced engine diagnosis. It covers repair stategies for cars and trucks that failed an emissions test; how to work on fuel injection; vehicle sensors; and OBD II. The book also contains an interactive training CD-ROM for any windows based computer. An amazing technology breakthrough allows the same CD to contain audio tracks playable on a CD player. The audio tracks are the author's instructional lessons on 5-gas analysis and OBD II (on-board diagnostics).
