Tune in and hang on as Brandon systematically troubleshoots a real-world problem on his vehicle.

In this video of Mastering Diagnostics, Motor Age Technical Editor Brandon Steckler implements a four-trace digital storage oscilloscope and current probe to capture a very elusive intermittent engine-starter fault that took over 10 days to reproduce. Brandon takes his time to carefully triage the situation with his eyes and ears before researching the system wiring diagram and building a diagnostic game plan.

Tune in and hang on as Brandon systematically troubleshoots a real-world problem on his vehicle. That’s right, no “bugs” placed here! Brandon’s car really does have an issue, and he needs it solved swiftly and efficiently.
