 Master OBD2 Scanners — Even as a Complete BeginnerÂ
Get a pro-level scanner on a DIY budget, diagnose problems yourself, and avoid mechanic scams.
Have a scanner but don’t know how to use half the features?
Â
You’re not alone—I’ve been there.
I once paid $700 for a part I didn’t need. Then I scanned the car myself, replaced a used sensor for $40, and the issue was gone.
That’s when I realized:
🔧 “It’s not about the tool. It’s about knowing how to use it.”
Â
🎓 This course is for you if you want to:
âś… Scan your car the right way
âś… Understand fault codes (not just read them)
âś… Use live data to find real problems: misfires, vacuum leaks, bad sensors
âś… Do resets, coding, battery relearns, throttle calibration
âś… Check used cars for hidden issues and mileage fraud
âś… Avoid wasting money on unnecessary repairs
✅ Help friends—or even make money with your new skills
Why learn from me?
I test OBD2 scanners for top brands like Launch, Topdon, Ancel, Thinkcar, and xTool—and I’ve worked with over 100 different models.
But I’m not just a tester. I actually use these tools myself to fix cars, find bad parts, read fault codes, and even do coding and service resets.
I’ve packed everything I know into this course—so you can skip the trial and error and start using your scanner with confidence. Even the cheap ones.
(And don’t worry, no boring 1-hour lectures—I hate those too.)

"Money well spent, I knew how to read fault codes but understanding live data is powerful for actualy diagnosing problems instead of changing parts."
Alex K.
"Loved the course, especially explaining different scanner types. Before I thought I have to spend $1000 for pro-level scanner. I got bi-directional Xtool you recommended for $89."
