A very user friendly and easy to use device.
The device works as advertised. It has an easy to follow user interface. There is good documentation and user manuals that are provided. I had an airbag warning light. The diagnostic indicated the passenger seat rail sensor was disconnected or defective. Looked under the seat and sure nuff…the connector was disengaged. Plugged it back in to the sensor. Reran the diagnostic. No problem was noted. I reset the warning light. Problem solved. The cost for a diagnostic at The Ford dealer was the same cost as the device. So effectively the cost of the device was zero.

Buy American
NEW out of the BOX, followed set up and software update. Plugged into 2 different cars and get the same message update software. Does not even find the car to read. Blank screen. I try to update and get nothing. Reached out to Customer service, but they can not help because this is an overseas product. Emailed overseas service and no response. Then I got a response and you need a Credit Card to access the functions. Come to find out the serial number was attached to a different email? How does that happen. finally sorted out with China at 2:00am EST. HAD to rest entire unit on their end and remove the fake email attached to my serial number. finally worked, but not worth the headache. Buy American!

Good enough
Great code reader, will display ALL codes! On the downside it doesn’t pair with the phone for internet connection, therefore unless you are close to a WiFi spot it will not send diagnosis results to your email.

I am typically clueless when it has to do with cars and how they operate, I thought using something like this would be confusing but using this LAUNCH CRP123I V2.0 OBD2 Diagnostic Tool is so simple and really good. The touchscreen layout is smart and intuitive, pretty straightforward I could navigate through the different options and understand everything with ease. The live data and ability to erase fault codes after fixing an issue is perfect, my ford 2017 has a check engine light system issue where is the gas cap is moist it shows the check engine light, without the diagnostic tool I would never have learnt that this was a thing. I was able to clear the message without a trip to the mechanic.I even learnt some new things from oil reset to brake bleeding, DPF regeneration and throttle relearn because of the features it has. I love how bulky it is and that i can save the tests to look at and show the professionals later on. Love my Launch Scan tool

This is a great code reader with a great screen for read out. I was very impressed by the quality and ease of use.I was getting a light in my car so I hooked this up. It ended up being something very minor that I could fix on my own. The code reader itself saved me 150 bucks because I didn’t have to go to a garage to get them to do it. Money well spent.I then used the system to change my battery. I had no idea that you needed to reset the BMS (battery management system) as per instructions so I did that without issues. The code reader hooks right into the car by a cable where it gives you real time read out of the systems for your vehicle. I don’t know if it would fit every vehicle but, I image the connection is universal.One thing I didn’t do which caused a few issues was I didn’t update it before use. So I would suggest doing that so you’re not having any issues. Once it was updated there were no issues at all so I suggest you do that first. I did have to send in a help request which was answered in 48 hrs. I was given instructions on how to fix the issue which in hindsight was my own fault and I should have read the directions and updated. It’s very easy to update just connect to Wifi and your pretty well good to go with a few buttons pushed to get that going. The code reader has lifetime free updates so no need to pay to get the newest updates when or if you get a new vehicle. To me that’s huge and makes the system even better.In the first week I saved 150 plus just to get a diagnostic on an issue with a fuse which was 10 bucks. It hasn’t paid for itself quite yet but I have no doubt it will very quickly. The code reader is high quality and my brother who is a mechanic tried it out and said ya this is a good one. He really liked it and is going to get one himself so that says a lot for the product to me.The code reader takes batteries it is not a rechargeable in case anyone wanted to know.

Review for: “LAUNCH CRP123I V2.0 OBD2 Diagnostic Scan Tool 4 Systems Engine ABS SRS Transmission Scanner with 7 Reset, OBD2 Code Reader with Oil/EPB/DPF/SAS/BAS/BMS Reset Throttle Adaption,Fit for All Cars”Brand: LAUNCHFirst look: The LAUNCH CRP1231 V2.0 OBD2 diagnostic scan tool came in a single-zippered case inside a box (24.9 cm x 17.7 cm x 7.6 cm) with the User manual, Quick start guide, USB charging cable, and diagnostic cable (with cap). The case is slightly smaller than the box.Measurements: The code reader is about 8 3/4″ x 4 3/4″ x 1 3/8″ (22.2 cm x 12 cm x 3.4 cm). The USB cord is about 29.5″ (75 cm) and the pin cord to the car is about 41” (104 cm).Charging: The code reader is rechargeable, either with the USB charging cable or plugging it into a vehicle with the diagnostic cable. The light will be red when charging and green when fully charged.Operation & Testing: I tried plugging it into the car, and it asked me language, time zone, then wanted to connect to the nearest Wi-Fi. There is no “skip” button so it needs to be connected to register and update the software. On page 23 in the manual under “Renew Software Subscription” it says, “for Creader Professional 123E PLUS / 129E PLUS, the preset diagnostic software can be free to use and update for two years. After it expires, it will become disabled. In this case, renew your subscription to unlock it.” I’m not sure if this remains free or if there is a fee to renew after 2 years.I found that when it was downloading then installing the new updates, the screen would go blank and the download would need to start over. In the settings, I found under “Display/Brightness” the “Sleep” time and set it to “Never” until the updates were complete. When it said it was complete, there was a button to “continue updates” and I clicked it, and then it started the downloads all over again. I would think it should know what it has done already and continue from where it left off. I would suggest not pressing “continue” if it says it is finished.There are also options in the settings menu for volume, screen capture, and units. You can enter your Shop information and email address and it will send you the reports via email when connected to the internet which is pretty cool.The screen is brightly lit up and is touch-screen, but there is no lighting on the buttons to the right of the screen.Opinion: As a backyard mechanic I was really impressed with this scanner. It does things other scanners I’ve used haven’t done, like graphs of the O2 sensors and battery that says if they are good or bad, and if the battery is charging in real time.It’s awesome that it charges while plugged into the car, so you don’t have to locate the specialized cord and plug it in when you want to charge it, although I would prefer it charged via USB-C as well rather than the specialized cord.
