Dont you just plug in a computer? – What a Real Scan Tool Can Do (That Cheap Ones Can’t)
I wanted to get into a bit more depth with diagnosis, so I made a video about the scan tool. After completing it, I feel there is so much more that could be shown, but this is already my longest video. Let me know if you would like more depth on this topic.
Think all scan tools do the same thing? Think again. In this video, we explain what a real scan tool can do, how it goes far beyond a basic code reader, and why professional diagnostics require more than just reading a check engine light.

Difference between a code reader and a full-function scan tool
How scan tools read live data, freeze frames, and system-specific codes
Why some codes don’t trigger a warning light
Features of pro-level tools (bi-directional control, resets, module access)
How scan tools help with diagnosing intermittent issues
OEM-specific vs universal scan tools
What your mechanic sees that you can’t
Real-world examples of what cheap tools miss
Whether you’re a DIYer, curious car owner, or looking to understand shop diagnostics, this video breaks it all down in plain language.
