- D7S Bidirectional Diagnostic Scan Tool, ECU Coding PMI OBD2 Scanner

As a professional mechanic with several years of experience, I have used a wide range of automotive diagnostic tools, and I must say that the Xtool D7 has been a pleasant surprise. I have been using it in my workshop for the past six months, and so far, it has exceeded my expectations in terms of functionality and performance. The Xtool D7 is extremely versatile. It has allowed me to perform comprehensive diagnostics on a variety of vehicles, from small cars to commercial vans. I can scan all the vehicle's electronic modules and obtain detailed information on error codes, real-time data, and active tests. This has been crucial for identifying hard-to-detect issues and ensuring accurate repairs. The Xtool D7's user interface is intuitive and easy to navigate. The menus are clear and well-organized, making it quick to find the function I need without wasting time searching through complicated manuals. The high-resolution screen displays graphics and data clearly, making it easy to interpret information while working on the vehicle. One of the things I appreciate most is the Xtool D7's ability to perform special functions such as key programming and DPF regeneration. These functions have been helpful on numerous occasions and have allowed me to provide more comprehensive service to my clients. Additionally, software updates are frequent and easy to install, ensuring that the tool is always up-to-date with the latest automotive models and technologies. Investing in the Xtool D7 has been an excellent economic decision. not just is the best scan tool between 300-400 price but It has helped me improve the efficiency of my workshop by reducing diagnostic time and avoiding the need for expensive subcontracted services. Furthermore, Xtool's technical support has been excellent; they are always available to answer questions and provide assistance when needed. I would recommend the Xtool D7 to any automotive industry professional looking for a reliable and comprehensive diagnostic tool. Its combination of advanced functionality, ease of use, and continuous support makes it a valuable investment for any workshop or vehicle repair service.

This scanner is so good for the price. It really blew me away with the ability to scan individual systems including the SRS airbag system. I recently bought a 2012 Xterra and I was able to use the scanner to diagnose a faulty airbag module instead of just buying random parts. I reset the airbag module (50$) and cleared the codes and the airbag light is off! I was ready to buy sensors and airbags but this scanner helped me spend 50$ instead of 500$. This thing also programs keys! I made a key for a family members 2019 honda clarity and it worked. I couldn't believe it. I highly recommend this scanner. You can't beat it's features for the price. With the airbag fix it already paid for itself. I am diy, and work on my own cars

The XTool D7S BIDIRECTIONAL Scanner was exactly what I needed for my 2021 Jeep Grand Cherokee WK2 3.6L. The scan tool is very easy to use and even simpler to set up and pretty straightforward. You will need to use your phone to connect the scanner to your hotspot if your Wi-Fi does not reach your vehicle after i easily did that I was able to read any and all codes along with easily doing a crankshaft position relearn after replacing my sensor. There were some hiccups with the 12 + 8 bypass cable trying to bypass the SGW firewall.I had to purchase a $60 yearly subscription through AUTOAUTH the product and then they scan tool worked like a dream . The product support team was super helpful and responded to every email within 12 to 24 hours at most. I would highly recommend this bi-directional scan tool for any at home DIY'ER that wants to save their money from paying a auto shop $250 to do a relearn which is required with the majority of the newer Vehicles made these days. I'd give it a 10 out of a 10!

I’m not a mechanic, I just work on my own stuff. With that said though, I have used this quite a bit already and it has definitely been worth the money. The last few things I used it for that come to mine was I used it to program new key fobs on my Jeep and my son’s Honda car, and I used it to troubleshoot some emissions alerts that my daughter’s car was having and verify the repair when I was done. The live logging was really helpful for that. I could see that an oxygen sensor kept losing voltage while I was driving. It works really good and it seems like every time I turn it on there are new updates for the diagnostic software so it does seem like they are really keeping it updated well. I’m happy with it

ADDITIONAL UPDATES! - - I'm again moving my review from an initial "Single Star" (then to "3 Stars") and now to 4 STARS! XTool has been EXTREMELY PROACTIVE in repeatedly reaching out to me and doing one follow up after another to assist me with the various issues I've been facing. So far, I'm EXTREMELY PLEASE with how they are doing everything in their power to resolves the frustrations and misgivings I was experiencing. "Caleigh" (w XTool) has reached out to me on numerous occasions, offering me REAL SOLUTIONS! - - I'm hoping to report again in the near future via another "Updated Review" and move this all the way up to a 5-Star Rating, but so far, XTool has exhibited OUTSTANDING CUSTOMER SERVICE and follow up! "Thank You", XTool !!! UPDATE!! - - I'm REVISING my initial 1 Star Review, up to 3 Stars, and may raise it even higher!! XTool staff have been extremely proactive and professional in the way the have reached out to me in order to resolve the issues I brought up. I will continue to work with them, but so far I am VERY SATISFIED as to how they're trying to make things right. Time will tell, but for now I did want upgrade my review due to how they QUICKLY REACHED OUT TO ME, and expressed their desires to correct the issues I've outlined. KUDOS to XTool so far, and "THANK YOU!!" I just received this unit 2 weeks ago (April 12th, 2026), and was busy with other things and didn't get around to even opening up the box until several days later. It was then that I discovered I'd been sent a USED UNIT, as it already had a user name, and a user email (which I CAN'T ERASE and put in mine without knowing the password the original owner put in), AND the unit (and subsequently the Subscription) was activated on January 17th of this year!! Secondly, this unit (as others have noted) is CLUNKY and not real intuitive. (I have a $40 Ancel scanner that I purchase via Amazon many years ago, and while not bi-directional, is far easier to use, and I've NEVER gotten a "Failed to Communicate" message from it, which I've already received numerous times with the D7S unit.) Not only did this unit FAIL in its claimed capabilities (despite numerous attempts, I was unable to do a "Relearn" on a new Crankshaft Position Sensor for our 2005 Buick Century w/the 3.1 l engine), but I was PERPETUALLY getting messages of "Refer to Service Manual" I guess that means I paid $400 for it to tell me to go buy the dedicated Service Manual for whatever vehicle I was working on. I also was frustrated by the fact that the "Auto Scan" feature is far from one, (again, my $40 Ancel scanner has never failed me in this task), as in just attempting to "Auto Scan" post plugging into the OBD-II Port for our '12 Highlander (standard V6 engine) the D7S kept giving me a "Failed to Communicate" message. It was only after I FIRST inputted into the scanner that it was a Toyota I was working on, did it recognize the vehicle. I had also wanted to reprogram keys for my '03 BMW 530i, and the wife's '12 Highlander, but after reading the comments here from others that have tried and failed, I'm not even going to bother before returning this unit. MASSIVELY DISAPPOINTED with the inability of this scanner to perform the functions it claimed its capable of, its perpetual "Refer to Service Manual" messages, and its inability to recognize the vehicle its been plugged in to! I'm also VERY UNHAPPY that I received a USED UNIT, with the subscription having been activated some 3 months ago by whoever the previous owner/user of this D7S was!! (Btw, one last note... though "tolerable" and not a "deal breaker" its obvious that whoever programmed this scanner, did not speak English as their native language, which one will note with the spelling errors for basic English words).

Doesn’t do half the stuff it advertises. Tried it on 3 cars and was pretty much a regular obd scanner with a few more options. Not worth the price that’s forsure

**UPDATE: No customer service!!! I want to program the keys on my 17 Traverse, the vide and other info sys this unit does it . My unit is missing the icon that will complete the key programming. It is up to date on software. I have tired several times to get in touch with XTool, there has been no answer to my emails and the phone system is a joke, they put you on hold for about 5 mins and then ask you to leave a message, and no one returns your call. Customer support is nonexistent at this point even though there is a 3 year guarantee!!! I down graded then to a 2 for their customer support. I just got the unit and I am already more impressed as to how it functions over the the D7.. I had the D7 but it started having issues so I returned it and bought this one, it was on sale. This unit has 3 years of software updates, that will save some money . The hardware seems to be the same as the D7 but the S model has different software and also comes with a USB port. The software on the D7S is way better than the D7. It is faster and more intuitive. It just runs so much smoother than its predecessor. Also the USB port allows for devices to be added, like a borescope. When connected to the vehicle it seems to run faster as well. The amount of functions it can do is awesome. A DIY mechanic will be able to use this a lot. Hopefully this model will be more durable than the last, only time will tell. I'm hoping they will add more attachments to make this device even better, wouldn't mind a wireless adapter to make it like the W model. Ill update this in 6 months to let you know how it goes over a longer period of time.

Great tool, After the first start you need to active it and register it to link it with your email for you and for the update. It need internet at first use. Then you can use it without internet anywhere you like. It works without internet but if you have internet it will update the files and look for solutions for your problem using the AI.
