Diesel engines are very simple – just compress some air and fuel and you get combustion. But with the advent of common rail fuel pressurization and delivery symptoms, diagnosis and repair became a complicated and time-consuming game. Add variable vane turbochargers, feedback EGR systems, and exhaust aftertreatment systems like Diesel Particulate Filters, Selective Catalyst Reduction, and Diesel Exhaust Fluid injection, and it’s hard to know where to start. System, code, and system diagnosis covered includes:

• Finding elusive Cummins & Duramax internal fuel leaks
• Modifications & retrofits that make sense
• Tips for getting DPFs to regenerate
• Help for stuck DEF messages and codes
• Easy tests for Cummins injector ball faults
• New Duramax pressurized fuel return
• Simplified no-start & hard-start diagnostics
• Variable Vane Turbo issues & diagnosis

Other published Cummins and Duramax repair information is inconsistent, and many of the flow charts run you in circles performing tests that would take days. In contrast, our approach looks for high-level indicators to make a better possible-cause list, and then offers multiple simple tests to trim that list as fast as possible without taking too much apart.

Cummins and Duramax are each comprehensively covered in separate sections, including special tools, workarounds, unused Scan Tool functions, and other great shortcuts.

From a simple high-level pass to system-specific tips, this seminar covers the entire diagnostic process. We have included dozens of real-world examples to prove that these strategies will find the root cause of your code or symptom in the shortest amount of time.
