Most “professional” scan tools hit you with $100–$300 per year just to keep using what you already paid for. With YOUCANIC, your scanner keeps working, even if you never connect it to the internet again.
Scanner works fully offline. Updates are free but optional — your scanner never stops working.
From sedans to semis — we’ve got you covered.

Real owners. Real savings. Real stories.
Verified buyers who saved hundreds — sometimes thousands — by diagnosing it themselves.
“Mercedes told me I needed all four ABS sensors replaced. YOUCANIC showed only one was bad. Saved me $2,700 on my first repair. Best purchase I ever made.”
“Diagnosed a wheel speed sensor on a BMW that the dealer misdiagnosed for $1,800. Found a glow plug on a Duramax and O2 sensors on a Buick. Great scanner.”
“Called 4 scan tool manufacturers — all made in the same place. YOUCANIC was different. Fixed my son’s car in a week — savings covered the cost of the unit.”
“Day it arrived I diagnosed ABS on a Volvo, then coolant sensor on a Mini. Paid for itself that afternoon — no lost wages, no diagnostic fees.”
“Scope switch was broken — YOUCANIC sent a new camera in days, no questions asked. Fantastic customer service. You folks should be very proud.”
“YouTube said replace the Air Valve Block. YOUCANIC found the right level sensor instead. Have an Audi, Silverado, and Mustang. Money WELL spent.”
Your scanner now explains the fix.
Every fault code comes with AI-powered insights — plain-English explanations, likely causes, and what to check first. No more copying codes into Google.
- Breaks down each trouble code in simple terms
- Shows likely real-world causes so you know where to start
- Tells you what to check first — skip unnecessary parts
- Built into the scanner — no subscription, no extra app
- Free for all existing UCAN-II-C owners via update
Most likely causes: Worn spark plugs (especially over 60k miles), failing ignition coils, vacuum leak, or low fuel pressure.
Check first: Pull and inspect spark plugs. If heavy wear or deposits, replace all and retest. If misfires persist, swap coils between cylinders to isolate.
