💡 Finally, a Scanner That Puts You in Control — No Subscriptions. No Guesswork. No Dealer Trips.

Ever spent $300 at the dealership just to confirm what you already suspected?

Or bought a “full system” scanner, only to find it needs a monthly subscription just to clear basic codes?

Yeah. We’ve been there too.

Most OBD2 scanners are either:

❌ Too basic — Only reads generic engine codes, useless for ABS, airbag, or transmission issues.

❌ Too expensive — Thousands of dollars and built for pros with years of training.

❌ Too limited — Locked to one car brand or need internet just to run.

❌ Too greedy — Charge extra just to unlock what should already be included.

❌ Too weak — Still leave you stuck at the dealership for advanced diagnostics.

That’s Why We Built the YOUCANIC UCAN-II

Created by real techs in the USA to give DIYers, shops, and everyday drivers the power of a dealer-level scanner — without the cost, confusion, or subscription scams.

✅ Works 100% offline — no WiFi required.
✅ No subscriptions. No brand unlock fees. Ever.
✅ Scan every control module — engine, ABS, airbag, transmission, hybrid battery, ADAS & more.
✅ Run bi-directional tests: fans, injectors, fuel pumps, EPB, throttle relearn, and dozens more.
✅ Covers 150+ makes worldwide — from 1996 to today, including gas, diesel, hybrid, and EV.
✅ Built-in touchscreen — simple menus anyone can use.
✅ Includes U.S.-based support + free lifetime updates.

Whether you're a weekend warrior, pro mechanic, or just tired of paying the dealer to read codes…

The YOUCANIC UCAN-II-C gives you the power of a $2,000 tool — for a fraction of the price.

Pro-Grade Diagnostics—At ¼ the Cost & No Yearly Subscription 

• ✅ Professional-Level Diagnostics — Access all available systems including engine, transmission, ABS, airbag, and more (up to 90+ ECUs on some vehicles). Compare: Autel MaxiSYS Elite & Snap-On Solus ($2,000+) offer similar access but cost 4x more.
• 💡 Beginner-Friendly, Mechanic-Approved — Easy-to-use Android touchscreen with guided menus. Perfect for DIYers, powerful enough for pros. Compare: Launch X431 and Snap-On scanners have steeper learning curves and less intuitive interfaces.
• 🔄 Free Lifetime Updates — Never pay for yearly subscriptions or brand unlocks. Updates are 100% free and the scanner continues working even if not updated. Compare: Autel requires at least $400/year after the first OR second year. Snap-On subscriptions are also recurring.
• 🚗 Gas, Diesel, Hybrid & EV Coverage — Supports nearly all vehicle types, including trucks up to 3500 series (e.g., RAM 3500, F-350). Compare: Many mid-range scanners from Innova or Launch lack full EV or diesel support.
• 🔧 40+ Service Reset Functions — Oil reset, battery registration, DPF regen, EPB, ABS bleed, injector coding & more. Compare: Most $500–$800 scanners only support 10–15 reset services. YouCANIC leads with the most functions in its class.
• 📊 4-in-1 Live Data Graphing — Track multiple sensor values side-by-side, record & export reports. Compare: Snap-On scanners offer this but at significantly higher cost. Most consumer-grade tools only graph 1-2 values.
• 🎮 Bi-Directional / Active Testing — Activate components (fans, windows, EGR valves, fuel pumps, etc.) just like a dealer tool. Compare: This feature is often missing in scanners under $1,000. Autel & Launch charge premium for this.
• 🌐 Supports 130+ Brands — Full global support across U.S., European, and Asian makes. No hidden unlock fees. Compare: Launch & Autel lock brand access behind subscription tiers.
• 📞 Free U.S.-Based Tech Support & Remote Help — Talk to real ASE-certified mechanics or let us remotely assist you.  Compare: Most brands offer slow or outsourced support. Remote diagnosis is rarely included.
• 🚫 Works Offline — Internet is only required for updates. Diagnosis, resets, and scans all work fully offline. Compare: Some Autel and Launch tools require online logins to function fully.
• 📦 All-In-One Coverage, No Hidden Costs — No add-ons, brand fees, or upgrade packages. Full access out of the box for ~$500. Compare: Snap-On, Autel MaxiSYS, and Launch PRO models easily exceed $1,200+ with optional upgrades.

Frequently Asked Questions

We offer a full refund on first-time returns, even if the unit has been opened and used, as long as it’s returned within the return window. However, if the scanner is purchased and returned more than once, a restocking fee of $30 will be applied to cover inspection, testing, cleaning, and repackaging costs. Used units cannot be resold as new, and each return incurs shipping and handling expenses. If you only need the scanner temporarily, consider our rental program:

$85 for one week, including both outbound and return shipping. This option is ideal for one-time use or short-term diagnostics.

 

Still have questions? Reach out to our support team—we’re here to help.

Does the scanner need internet to work?

No, scanner will work without internet. Internet is only needed for updates and emailing reports.

Does it work with cars outside of USA?

Yes, it has worldwide vehicle model coverage for cars 1996 and newer. Wroks also on some OBD-I vehicles with adapters.

Where is the product made?

We design the product in Baltimore, MD and manufacture it in China to maintain quality while keeping costs affordable.

Where is support located?

Our support team is based in Baltimore, MD and available Monday-Friday, 9AM-4PM EST.

Do you ship worldwide?

Yes! Add the product to cart and enter your address to see international shipping rates.

Will I have to pay duty taxes?

Depends on your country's rules. We don't collect duty or VAT tax - these may be charged upon delivery according to local regulations.

Are updates free?

Yes, updates are free for the lifetime of the product. We regularly add new car models and features.

How do I update the scanner?

Simply connect to WiFi and click the update button - it's that easy!

What if I have trouble connecting to my car?

With your permission, we can remotely access the device and help resolve any connection issues.

Can this device code/program modules?

While the scanner can perform some coding tasks like battery registration, injector coding, and TPMS sensors, it's not designed as a primary coding tool. It may not support control module coding or VIN-to-module coding.

Can I print diagnostic reports?

Yes, you can print directly to any WiFi printer and email reports to any email address.

Can I record live data?

Yes, you can record live data while driving and play it back later for analysis.

Why can't I buy this scanner on Amazon?

We choose to sell directly to our customers to provide better service, support, and value. By cutting out middleman fees, we can offer free lifetime updates, US-based technical support, and remote diagnostic assistance - services we couldn't provide through Amazon. This direct relationship also ensures you receive a genuine YOUCANIC scanner with full warranty coverage and access to our expert support team in Baltimore. While it might be more convenient to buy on Amazon, we believe giving you direct access to our team and full product support is worth much more than one-click shopping.

Adapter for 1996-2002 Mercedes-Benz vehicles with 38-pin port under the hood. Available only with the purchase of a YOUCANIC UCAN-II full-system scanner. This adapter allows you to access all control modules and systems on the models with the 38-pin port. Without this adapter, you may only be able to access the engine control unit if your Mercedes-Benz is between 1996 and 2002 and has the 38-pin port. 

This adapter is only available for customers who have purchased the YOUCANIC full-system scanner. 

See models with 38 pin port

Pre-1996 models may or may not be supported. 

The YOUCANIC 12+8 Adapter is a must-have accessory for automotive professionals and DIYers who need full diagnostic capabilities on late-model FCA  vehicles (see list below).

 This adapter is specifically designed to bypass the factory-installed Security Gateway Module (SGM) — a system that blocks most aftermarket scan tools from performing advanced diagnostics beyond basic code reading and live data.

Without this adapter or AutoAuth credentials, scan tools attempting to communicate with FCA vehicles equipped with an SGM will display errors such as:

“Device unable to communicate with the control unit.”

This adapter allows your YOUCANIC Full System Scanner (and other scan tools) to seamlessly access all modules for bi-directional control, active tests, resets, adaptations, and advanced diagnostics — just like the dealership scan tools.

✅ Compatible FCA Brands:

• Chrysler

• Dodge

• Jeep

• RAM

• Fiat

• Maserati
  

• Alfa Romeo

📌 Common affected models include: Grand Cherokee, Wrangler, Charger, Challenger, Pacifica, 300, RAM 1500+, and more.

🔒 What is a Security Gateway Module (SGM)?

Starting in 2018, FCA began installing SGMs in most of their vehicles as a cybersecurity measure. While it protects the vehicle network, it also blocks aftermarket scan tools from sending commands or performing service functions — unless bypassed.

Estimated SGM Implementation by Model Year:

• 2017: ~20% of vehicles

• 2018: ~50% of vehicles

• 2019: ~90% of vehicles

• 2020+: ~100% of vehicles

🔌 How the Adapter Works:

• Connects to the YOUCANIC Full System Scanner (UCAN-II-C or UCAN-II-P)

• Plugs directly into the vehicle’s 12+8 diagnostic port

• Bypasses the SGM for full access to all vehicle modules, including:

  • ABS

  • Airbag

  • Transmission

  • Body control module

  • Climate control

  • Steering and more

🔍 SGM Location:

The Security Gateway Module is typically located in:

• Behind the glove box

• Passenger side kick panel

• Behind the infotainment/radio unit

⚠️ Important Compatibility Note:

This adapter is only for verified YOUCANIC scanner owners.
If you purchase this adapter without owning a YOUCANIC full system scanner, your order will be canceled.

💡 Already own the scanner? Be sure to use the same email address from your scanner order during checkout to verify eligibility.

📦 What’s Included:

• 1x FCA 12+8 Bypass Adapter
  

🛠️ Bring Dealership-Level Access Home

Skip the limitations and unlock your vehicle’s full potential with the YOUCANIC 12+8 Adapter. Whether you’re a shop tech or an advanced DIYer, this tool gives you complete control — no subscriptions or AutoAuth required.

• 2017 and earlier FCA vehicles generally do not have SGW.

• 2018 model year onward: SGW became the standard across nearly every FCA/Stellantis brand, though some overlap years (like Ram DS “Classic” trucks) had mixed configurations.

• Even commercial and fleet models (ProMaster, ProMaster City) eventually received SGW after 2019.
