Stop Paying Dealership Diagnostic Fees
Dealer Level OBD2 Scanner With Bi-directional Control And No Subscription
Ever paid 200 to 300 dollars at the dealer only to confirm what you already suspected about a check engine light or ABS warning? Or bought a “full system” scan tool and then found out you must pay a yearly subscription just to clear basic codes?
The YOUCANIC UCAN-II gives you professional-level diagnostics, bidirectional testing, and full system coverage, with no yearly subscription, no brand unlock fees, and a scanner that keeps working even if you never update it again.
Why Most OBD2 Scanners Let You Down
Most generic OBD2 scan tools fit one of these problems:
- ❌ Too basic – Only read generic engine codes and are useless when you need ABS, airbag, transmission, or body module diagnostics.
- ❌ Too expensive – Professional shop scanners cost thousands and assume years of training.
- ❌ Too limited – Locked to one brand or need a constant internet connection just to work.
- ❌ Too greedy – Brand unlock fees, paid features, and yearly subscriptions just to keep full system access.
- ❌ Too weak – Still send you right back to the dealership for advanced diagnostics and real bi-directional tests.
- ❌ Poor support – Support that answers slowly, is only email-based from overseas, and often not even from a real technician.
That Is Why We Built The YOUCANIC UCAN II
The Youcanic UCAN II (current hardware version C) is a full system OBD2 scanner and bi-directional scan tool designed by working technicians in the USA. It gives DIYers, small shops, and everyday drivers the power of a dealer-grade diagnostic scanner without subscription games or complicated software.
Version C of the UCAN II platform includes double the memory, double the internal storage, and around 25 percent more battery capacity compared to earlier units, so scans run smoother and you can work longer between charges.
Core Advantages
- ✅ Works completely offline – no WiFi required for diagnostics.
- ✅ No subscriptions and no brand unlock fees at all.
- ✅ Scanner keeps working even if you never update it again.
- ✅ Dealer-level access to all available modules on supported vehicles.
- ✅ US support with real techs and free lifetime updates.
Professional Features
- ✅ New topology map to visualize and scan every control module quickly.
- ✅ Bi-directional tests for fans, injectors, fuel pump, EPB, throttle relearn, and more.
- ✅ Full system coverage for engine, transmission, ABS, SRS, TPMS, body, hybrid battery, ADAS, and more.
- ✅ Simple touchscreen interface that new users learn very fast.
Whether you are a weekend DIY mechanic, a small shop, or just tired of paying dealer diagnostic fees, the Youcanic UCAN II C gives you the capabilities of many two-thousand-dollar professional scan tools for a fraction of the price.

How YOUCANIC Compares To Autel, Launch, Snap On, Thinkcar 689bt and Others
Many buyers compare the Youcanic UCAN II C to tools from Autel, Launch, Snap On, Innova, and Foxwell. The UCAN II C focuses on three things that matter most in real-world use: full system coverage, bi-directional control, providing helpful support, and predictable total cost of ownership.
- ✅ Subscription cost – Youcanic includes free lifetime updates and the scanner keeps working even if you never update it again. Many Autel and Launch tools charge yearly fees, and higher end Snap On tools are among the most expensive on the market.
- ✅ Brand coverage – The UCAN II supports more than one hundred manufacturers with no per brand unlock charges. Some tools from Autel and Launch charge extra for advanced coverage or regional brands.
- ✅ Bi directional tests – On Youcanic, active tests like fuel pump, EPB, fans, injector cut out and more are included. Many consumer grade tools from Innova and Foxwell do not offer the same level of control.
- ✅ Support quality – Youcanic support is based in Baltimore, Maryland, with technicians who use this scanner every day. Many competing brands rely on slower overseas support that is often only email-based.
| Feature | YOUCANIC UCAN II C | Most Scan Tools |
|---|---|---|
| All System Diagnosis | ✅ Full module access across all systems | ❌ Engine only, limited ABS and transmission access |
| Bi Directional Control | ✅ Fuel pump, EPB, windows, fans, and more | ❌ Rare, locked, or missing |
| Updates | ✅ Free lifetime updates and scanner still works if you never update again | ❌ Yearly fees or per brand charges |
| Coverage | ✅ 150 plus makes including gas, diesel, hybrid, and EV | ❌ Limited or paywalled |
| Ease Of Use | ✅ Touchscreen with simple Android based interface | ❌ Complex menus and steep learning curve |
| Support | ✅ US based phone and remote support, often same day reply | ❌ Outsourced or slow email only |
What Real YOUCANIC Owners Say
“This scanner has great functions and it is easy to use. I take care of vehicles for my extended family. Recently diagnosed a wheel speed sensor on a BMW 230 that the dealer misdiagnosed for 1800 dollars just for scanning. The real time output display was great, found a glow plug issue on a Duramax, and oxygen sensors on a Buick Terraza.”
“This is the best scan tool any individual or small automotive shop can get without spending thousands. Simple instructions, lifetime updates. Got it for my Mercedes, can check all modules, engine, electrical, suspension, and even bleed brakes. I should have bought it years ago.”
“Works as expected with my ninety four Delica, zero eight Jaguar, ten Audi, and twenty eighteen Tacoma. Clears codes and emails reports directly. The Bluetooth connection works every time. System has passed my expectations. Great value for professional diagnostics.”

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 is returned within the return window. If the scanner is purchased and returned more than once, a 30-dollar restocking fee applies to cover inspection, testing, cleaning, and repackaging costs. If you only need the scanner for a short time, consider our rental option:
Rent a full system scanner for one week, including outbound and return shipping, which is ideal for one-time or short-term diagnostics.
Still have questions? Reach out to our support team, we are ready to help.
Does the scanner need the internet to work?
No. The scanner works completely offline for diagnostics and service functions. Internet is only needed for software updates and emailing reports.
Does it work with cars outside the USA?
Yes. It has worldwide vehicle coverage for cars from 1996 and newer and supports some OBD one vehicles with the proper adapters.
Where is the product made?
The product is designed in Baltimore, Maryland and manufactured in China. This keeps quality high while keeping the price more affordable.
Where is support located?
Our support team is based in Baltimore, Maryland and available Monday to Friday from 9 AM to 4 PM Eastern Time.
Do you ship worldwide?
Yes. Add the product to your cart and enter your address to see international shipping options and rates.
Will I have to pay duty taxes?
That depends on your country. We do not collect duty or VAT. Your local customs office may collect these taxes when the package is delivered.
Are updates free?
Yes. Software and coverage updates are free for the lifetime of the scanner. We regularly add new models and features, and the scanner will keep working even if you decide not to update.
How do I update the scanner?
Simply connect the scanner to WiFi and tap the update button on the device. No computer is required.
What if I have trouble connecting to my car?
With your permission, our team can remotely access the scanner and help you solve connection or communication issues.
Can this device code or program modules?
It supports functions like battery registration, injector coding, and TPMS sensor programming, but it is not intended as a full ECU programming or control module coding tool.
Can I print diagnostic reports?
Yes. You can print reports directly to a WiFi printer or email them to any email address and print from there.
Can I record live data?
Yes. You can record live data while driving and replay it later for detailed analysis, which is very helpful for intermittent issues that do not always appear right away.

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.
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.

-
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.
