What Is The Difference Between A Code Reader And A Diagnostic Tool?

A basic code reader displays stored fault codes. A professional diagnostic tool reads live data, runs component tests, performs bidirectional controls, and logs graphs to verify causes. Using live values and functional tests allows accurate fault isolation, reducing parts swapping and repeat failures.

How Do You Diagnose Electrical Problems In A Truck?

Start with the complaint and visual inspection. Verify battery health and grounds, then measure voltage drop across suspect circuits under load. Use a scan tool for codes and live data, interpret wiring diagrams, and isolate sections systematically. Confirm repairs with retests and a final scan.
