Today’s vehicles have as many as 30 different onboard computers, and even more sensors, inputs, outputs, and codes, making a systematic diagnostic approach imperative to solving OBD-II codes quickly and efficiently. In this program, two ASE-certified instructors use a strategic seven-step approach to troubleshoot two common “check engine” light concerns, with special focus on how a step-by-step flowchart diagnosis can often point to what’s causing the code to appear. Correlates to ASE and NATEF standards, with viewable/printable ASE/NATEF task correlation checklists available online. A Shopware Production. Part of the series Strategy-Based Automotive Diagnosis.
