YOUCANIC UCAN-HD-A Heavy-Duty Diesel Truck Scanner – Full-System

As someone who frequently tackles automotive diagnostics and repairs, I'm consistently on the lookout for tools that bridge the gap between enthusiast-level capabilities and professional-grade performance. The YOUCANIC Pro OBD2 Scanner – Advanced Full-System Diagnostic Tool has not only met but exceeded my expectations, proving to be an indispensable asset in my toolkit.

From the moment I began using this scanner, its "dealer-level access" was immediately apparent. Unlike many consumer-grade OBD2 tools that offer limited insight, the YOUCANIC Pro truly delivers on its promise of comprehensive full-system diagnostics for "all makes." I've successfully used it across a range of vehicles, from everyday commuters to more specialized models, and each time, it has provided a depth of information previously only accessible with much more expensive, brand-specific equipment.

The "bi-directional controls" feature is a significant standout. This functionality allows not just for reading fault codes but also for actively commanding various components and systems, enabling more thorough testing and troubleshooting. This is a massive time-saver and provides a level of diagnostic precision that is crucial for accurate repairs. Whether it's cycling ABS pumps, performing relearns, or testing actuators, the YOUCANIC Pro handles it with impressive ease.

Another truly remarkable benefit is the "free lifetime updates." In the ever-evolving automotive landscape, having a diagnostic tool that stays current with new vehicle models and software protocols without additional recurring costs is a huge advantage. This commitment to ongoing support from YOUCANIC ensures the scanner remains relevant and effective for years to come.

The user interface is intuitive and well-organized, making complex diagnostic procedures surprisingly straightforward. Even for those new to advanced scanning, the learning curve is minimal, allowing users to quickly leverage its powerful features.

While my experience has been overwhelmingly positive, it's reassuring to know that YOUCANIC prioritizes customer satisfaction. Their explicit invitation for feedback and dedicated support team at [****] demonstrates a genuine commitment to their users.

In conclusion, if you're a serious DIY enthusiast, a small garage owner, or anyone looking for a robust, feature-rich, and future-proof diagnostic tool, the YOUCANIC Pro OBD2 Scanner is an exceptional investment. It delivers professional-grade capabilities at a fraction of the cost, making it a truly valuable addition to any automotive diagnostic arsenal. Highly recommended!

Bought the Youcanic Ucan-II-C to use on various car's, so far I have tested it on a 02 GMC Envoy and an 06 BMW E66.
I was able to quickly diagnose and find all issues and do the appropriate repairs and successfully clear the code for each repair.
Very pleased with this purchase! The build quality is very durable and should easily last a long while.
Good performance for low wait times, I was surprised how quick it completes each task.
Also like the support options while connected to wifi for each code that appear, if you need this is handy.
Video scope works great and does capture.
Wireless OBD is also nice for working under the hood+ live data options.
I definitely recommend Youcanic full diagnostic scan tool, Amazing Features and Amazing Support for an Amazing price.
I also wanted to say the Support Team at Youcanic shipping is top notch 5 star service.
Speciaythanks to Olivia & Melisa + Youcanic shipping Team! Much Thanks To you all

This heavy duty truck scanner went above and beyond what I expected. Build quality is excellent, and I really like that it comes with a solid carrying case to keep everything in one place. I tested it on my truck and two work semi-trucks, and so far I have been impressed. It’s super easy to set up, touchscreen works great, and it gives you diagnostics fast and clear. If you own a truck, this thing is super useful — I’d say it’s a must have. Beats scanners from the competition that cost $2k or more.

Saves trips to the dealer for diagnostics and maintenance that you can do yourself. After careful consideration and research, I chose YOUCANIC and you should to! I called 4 of the big scan tool manufacturers and found the majority were all manufactured in basically the same location. However, YOUCANIC had a significantly different approach to solving malfunctions focused on the end user with how to assistance and minimizing out of pocket cost after purchase. No annual subscriptions, instant access to diagnostic reports, videos, one on one troubleshooting assistance and more. I fixed all the issues with my son’s car in a week after purchase and the cost savings covered the cost of the unit, now each additional is money in the bank. You can spend more for the same functionality so long as you pay associated fees year after year and settle for lackluster performance or you can skip that, get customer support directly from people who just want to help you get back on the road. Buy the YOUCANIC, save money, and be pleasantly surprised.

First attempt. 2008 Prius SRS issue with passenger light stuck in off for years . After connecting and going in and out this issue was corrected and my TPMS system was reset as well . The software did what it was suppose to do . An amazing investment and the staff was always quick to return on a call away . Highly Recommended .

This scanner has great functions and it's easy to use. I take care of vehicles for my extended family and some friends. So far I've diagnosed a wheel speed sensor on a 2017 BMW 230 (diagnosed incorrectly by dealer at a cost of $180.00 just for scanning) the real time output display was great, a glow plug on a 2006 GMC Duramax, and O2 sensors on a 2007 Buick Terraza. And also reset maintenance messages after performing oil changes and installing new brakes. It connects quickly with the smart vin and the battery in the scanner seems to have a very good working time.

I received my scanner about a week and a half ago and immediately use it to diagnose an ABS sensor light that was on my daughters Kia Sorrento that the other scanners we had were unable to read or find a code. This scanner immediately pinpointed the bad wheel sensor and we were able to fix it in a few minutes.
Seems sturdy and the battery lasts a long time on a charge so I am looking forward to using this in the future!

Five stars all the way. I’m a small business owner: This is the first scanner I have ever owned. In the past three weeks: Mercades ABS light was on. Mercades told me I needed all four ABS sensors replaced. I decided to purchase the Youcanic scanner. Result, I only one sensor was bad (I replaced it). On my first repair, Youcanic saved me $2,700.00. I also figured out that I had a bad clock spring in two other vehicles (easy to change) and a bad ABS sensor in another. Cold weather would not allow a service truck to start. With a little research, the Youcanic scanner shower me what was the problem (fixed). Best purchased I ever made.
The bi-directional communication is really the greatest thing to have when using a scanner. This scanner is very easy to use. Well thought out controls. Very durable.
The only thing I would like is, when using “Live Data” split the screen so that more data can be viewed at one time. Oh, the battery drains fairly quickly (couple of hours of use) although, I don’t have another brand scanner to compare it to, this could be normal. Only recognized VIN on 2 of 5 vehicles. I had to type in the VIN then the information popped up. Not a big problem.
Customer service was fantastic. The scope switch wasn’t mounted properly. Youcanic sent a new camera. It arrived in a couple of days.
Thanks Youcanic for a great product and great customer service. You folks should be very proud of your product. Good Job.

First, I decided to buy this product because of the professional reviews I read. I used the Youcanic on a 2004 S430, as it was having issues with "Airmatic Visit Workshop." YouTube was leaning towards replacing the Air Valve Block, however the Youcanic identified B22/9 Right Level Sensor. After a closer inspection, the component did need to be replaced and the issue was resolved. I have 2015 Audi, 2016 Silverado and 1999 Mustang, so this has been and will be money WELL spent. Got it, Get it, you will Love it.

I rented the scanner to troubleshoot my 2012 Mercedes GL550, no start problem. I was skeptical until I tried it. I was able view the real-time data as I turned to key in the ISM, which showed me that the ISM was not sending the signal to the start relay to allow it to start. I was able to repair the ISM, that had a broken connector and was able to see the signal from the ISM to the relay. The car still wouldn't start, so I went further, and found that the starter was also bad. I was very pleased to save a bunch of money, even with the rental fee,taken into consideration.
The only thing I had an issue with was the fact that the scanner wasn't able to test the starter, which I had to remove and het tested. I liked it so much that I bought one, with no hesitation. Even woth the purchase price plus the rental fee, it was much cheaper than letting the Dealer/Stealer fix the problems. Lol

The YOUCANIC UCAN-II-B PRO Full System Scanner is an awesome tool. It paid for itself on my first use. We have 5 cars from 1997 to 2021 and it works with all of them. On my GMC Sierra Denali, I was having issues with Stabilitrak and once I plugged this in, it was obvious that I had a grounding issue. I did not have to spend hours on it as we started with the battery and found that a ground had become loose. Way cheaper than the dealership.

Had an issue with my Dynamic Multicontour seats in my S600. The scanner identified the issue and with the ability to reset error codes and then provocating the error over and over i was finally able to locate the root cause: a broken air-pipe in the driver seat. Was able to fix this myself. Love the scanner. Robust and easy to use.

I highly recommend this to the home mechanic. I had a few issues to sort out on my 08 volvo and this was the way to finish out my work.
I set the transmission to learn, recalibrate the ac system, sorted out my haldex AWD, got rid of my airbag warning, and cleared up a traction control issue.
Plus cleared out old codes from over the years.
It's easy to use and was in new condition.
The company is easy to work with also.

The whole process went very smoothly from beginning to end. Before renting I asked if the tool could do what I needed to and tech support confirmed it could. Renting was straightforward and the tool was easy enough to use. Did not need to schedule a remote tech support session. Once I was done with the tool I emailed them asking for a return label which was they promptly emailed me. Got my refund when they received their tool back. 10 out of 10 would rent from them again.

An affordable. fully-interactive diagnostic scanner was just a passing dream of mine until I purchased the UCAN-II. The day it arrived I updated the software and immediately afterward used it to diagnose. solve and reset ABS issues on a 2014 Volvo S60. I then diagnosed and solved vexing and persistent coolant sensor problems on a 2014 Mini. Didn't have to find a local repair shop or drive long-distance to a dealer, book and wait for an appointment, take time off work, drive to the shop, nor pay a diagnostic fee and hope for an honest diagnosis and quick turn around. That afternoon my UCAN-II paid for itself in no lost wages, no diagnostic fees and no run around. With the UCAN-II I discovered the actual problems, researched the repair procedures from the UCAN-II browser, ordered new parts, made and verified the repairs, then cleared the codes and returned the vehicles to service. That is the definition of a dream come true for a home mechanic. Once you hold the UCAN-II and use it, you will never want to do car repairs without it.
