I called those fancy scan tools a waste of money for years
I ran a small shop for a decade and thought my basic code reader was enough. Then a 2018 Ford F-150 came in with a weird transmission shudder and no codes. A buddy let me borrow his high-end scanner, and it showed a live data PID for torque converter slip that my cheap tool couldn't see. We swapped the converter and the problem was fixed in a day. That one job paid for half the tool. How many of you actually use the advanced features on your scanners, or is it still just for clearing check engine lights?
