When it comes to advanced vehicle diagnostics, truly focusing on the basics might sound cliché, but it is the root of every diagnostician’s success. Automotive diagnostic workflows for technicians becomes crucial because efficiency is equally as important as accuracy.
Consider the case of an engine misfire diagnosis on a modern vehicle. Although the same physics apply, the complex vehicle configurations of today’s makes and models leave little room to perform the testing required (as it was conducted in earlier configurations). Instead, leveraging a more logical automotive diagnostic strategy means working smarter, not harder.
Leveraging oscilloscope diagnostics, for example, means implementing simple-to-perform tests that yield a ton of information for a minimal amount of time or energy invested. Relative compression testing is a prime example of monitoring each cylinder’s compression stroke as mechanical/electrical load on the starter motor.
In this article, technicians, including advanced level techs, will learn a strategy for building a game plane to approach virtually any diagnostic issue on any vehicle they encounter.
