Each problem vehicle presents a unique set of conditions that must be analyzed and understood before a successful diagnosis and repair can be achieved.

In “A Streamlined Approach to Diagnostic Dilemmas,” Brandon Steckler explains how technicians can combine an understanding of the physics common to all vehicle systems, basic testing techniques, available service information and modern diagnostic tooling to solve seemingly difficult dilemmas, with ease and efficiency, regardless of vehicle type.

The manual begins with an overview of the fundamental knowledge that is the basis for all troubleshooting and concludes with a series of case studies to illustrate his problem-solving approach. 

The coil bound 8-1/2" x 11" manual includes 91 full-color pages.
