OBD2 Scanner CRP123I V3.0 Elite, 2026 Lifetime Free WiFi Update Scan Tool, FCA SGW, CANFD&DoIP, SAS/Throttle/Brake/BMS/DPF/Oil/ABS Service Multi Systems Car Scanner, Battery Test, Auto VIN

UPDATE: the unit won't work if you don't do updates. It works fine once you do updates. I am getting various transmission codes. I've researched the forums and YouTube. This allowed me to look at the specific codes (P0843, P0877, P0751, etc) and the components. I was able to look at all my shift solenoids, Pressure switch's, and trans temperature at the same time. It was 15F outside and I was able to see the trans temperature read 80F, and if I cleared the code and shifted it went to limp mode, and then the transmission read -40F. I'm replacing the Pressure Switch assembly (ALLISON TRANSMISSION 29546972 PRESSURE SWITCH ASSEMBLY 5-SPEED & 6-SPEED 01-18) and expect the temperature to read correctly. The gauge reads correctly today after clearing the code. I bought this for my Chevy 2500 with a Duramax engine to read a code. Basic code readers were giving me a generic code (P0700) and this was snow to give me more specific detail (shift solenoid 2) as well as the ability to move monitor data. Similar to my CTS Edge scanner it can show balance rates, and SOOOO much more. It was worth the $150 for figuring out my error code so I could research potential solutions (low fluid, frayed wires, bad harness) instead of constantly having a no shift problem. Some say the software stops working in a few months, but after two days of playing with it I'm happy for the one time. It automatically detects your vin. Also, it stores stuff on servers in China (if you couldn't tell by the price) so if you want USA made this isn't it. If you shop at Walmart, Target, or Auto Zone you'll be right at home. This is not a programmer. It won't turn off features you don't like. It could help diagnose a misfire, monitor transmission or engine coolant temps, tell you the flow plug status, etc.

Easy to use, great quality and connectivity.

REPAIR SHOP TOLD ME MY TURBO WAS BAD AND THEY CAME UP WITH ERROR CODES TO REFLECT IT... THEY SAID $4500 TO REPLACE EVERYTHING WITH NO GUARENTEES... I PURCHASED THIS UNIT FROM LAUNCH AND IT QUICKLY INFORMED ME THE O2 SENSORS WERE BAD. TWO TOTALLY DIFFERENT TROUBLE CODES - TURBO VS O2 SENSORS... THIS WORKED EXACTLY AS ADVERTISED AND IS MY ONE GO TO TOOL FOR MY FREINDS THAT NEED HELP... THANKS FOR A GREAT PRODUCT THAT IS WORTH THE MONEY AND SOMETHING THAT IS RELIABLE...

Good scanner but wish I would of got a bidirectional one so I could test individual modules

I have a ‘03 Jetta that is a surprisingly great little car considering it’s age. Only problem in the last 5 years is some EVAP stuff which is causing me to fail CA smog check. I really got this scan tool to scan for emissions readiness so I can see which monitors are not ready without running to my auto shop every few days. Yesterday I got my check engine light though, and I used this tool to scan DTC. It told me exactly what my mechanic had suspected last time I was at the shop for the purge valve repair, “very small leak in evap system”. So I knew my mechanic was correct and honest, I knew what was wrong with the car, and I knew I needed to get the smoke test next to find the leak all thanks to this scan tool. It’s AMAZING. Very easy to use, lots of features, and really will save time and money. I am a blonde female so I am immediately pegged by some mechanics as stupid and easy to trick. With this scan tool, google, and my Chilton manual, I can speak to them in their own language. When you get this scan tool just charge it up; CHARGER IS IN THE CARRY CASE! Then connect to your WiFi and update! Then plug it into your port in your car and turn on the ignition. You can get a full health report. My VIN was not auto-detected, that was my only disappointment but no big deal. I was able to clear an old airbag code that was due to my battery dying, and then I found my leak. Everything else checked out. wish I got this sooner, actually, it is sooo informative. You can leave it plugged in when you drive and get live data too. I’ll do that when my car is back from the mechanic. I’ll update my review if anything changes, but I highly recommend you try this scan tool. Update: one month later I finally got my monitors ready and the photo shows the live data report for my car. Took it for smog and passed. Those monitors are a main component of smog check. So if they all pass, you will probably pass (they still have to inspect, and check tailpipe output, but monitors are main thing). In my state it’s legal for them to charge you over and over even if you fail. So knowing you will pass or fail ahead of time really adds up savings. My mechanic charges twice EVEN IF THEY do the repairs. Sux but never again!

Using this OBD reader I was able to resolve my airbag warning light problem on my 2009 Mazda 3. Using the codes from the reader and internet research I was able to fix the problem which in my case turned out to be a burned out bulb for the Passenger Airbag Disable warning indicator light. This OBD reader was easy to setup: time zone, WiFi and email address. I like the feature of being able to send the diagnostic report to my email. And the ability to clear codes. Also, doing the updates is easy on this model using the built in WiFi. It was definitely time to replace my outdated OBD reader of over 10+ years and I would have paid around $200 at the dealership just to have the diagnostics done. Now I have this amazing ODB reader for future car maintenance. I did not rate Tech Support because I did not need to use it.

This is a beautiful item. Comes with a very nice fabric case. But is useless off-grid, and creates unacceptable network security vulnerabilities when used on-grid. When first powered-on, device asks for language (page 1) and time zone (page 2). The third page wants a WiFi network ID, a login password, and a valid email address...among other bits of personal info. Trying to skip any page produces a system error, and the system reboots. Our WiFi security uses MAC address filtering and static IP addresses. Item's package/stickers/documents contain no MAC address or serial number info. I assume that MAC address filtering must be disabled to use this device. Documents have no setup info for item's network interface. I assume that the device expects DHCP support (and does not accept a static IP assignment). The item has an internal battery, and is rechargeable. If I forget to turn it off after use, I assume that it will remain online, providing global internet access to our internal WiFi network(s), until the battery dies. I'm sorry to return this item. It looks like it could be very useful. But I cannot have an IOT item that contains important personal + company info, and phones home every time I use it.

This one is extremely easy to use, very responsive touchscreen. I especially like the graphing feature and it’s nice to be able to use something with a big screen instead of using your phone to view the data. For the price, this is the one that every do it yourself or should be getting. The lifetime free updates is worth its waiting gold. Other units cost between two and $500 a year to update. Where this one is free and stays updated forever. This will definitely pull codes that the other ones will not. Those cheaper ones that you plug into the port and then link to your phone, they don’t pull all of the codes like this one does. And for the price you can’t beat this. In addition to the 7 resets that are for life. Other units expire after the 1 or 2 years of subscription. On this they do not expire! Launch is a great company to deal with, and this seller stands behind the product extremely well. You can feel confident buying from this seller.

I was expecting a bit more from this scanner for the price. It works fine and reads the main systems, but it doesn’t really do much more than a basic £5 Bluetooth OBD reader. I ended up returning it and getting the Thinkcar 689BT instead, which offers a lot more features for slightly more with a discount code. The build quality is good though, and it’s easy to use — just not the best value in my opinion.

Nunca he tenido un escáner con todo el tipo de funciones que este tiene pero estoy maravillado con el. El uso que le daré no será en capacidad de profesional. No soy un experto en el tema de la mecánica así que mi opinión del producto no será tan amplia y detallada como aquella de un experto. De todos modos espero que mi aporte le pueda ayudar a toda aquella persona que esté considerando comprar este excelente escáner. ***PRESENTACIÓN y OPERACIÓN DEL PRODUCTO DEL PRODUCTO*** El escáner viene con su cable cargador, cable que se conecta al puerto de comunicación del vehículo y su manual de operación. El escaner en si es una tablet que ya viene con su carcasa protectora y una mica de plástico que protege la pantalla. En caso de llegarse a caer no da la sensación de que se vaya a dañar. El modelo que adquirí cuenta solamente con el botón de encendido, puerto de carga y conector de puerto de comunicación del vehículo. El hecho de que no tenga botones físicos me agrada ya que minimiza la posibilidad de que se deposite polvo y grasa entre los botones que a su vez pueda llegar a dañar el escaner. Es relativamente pesado pero cómodo de sostener con una sola mano. Al iniciar el escaner se te pedirá que configures tanto el lenguaje como zona horaria, contraseña de WiFi (MUY necesario para tener acceso a internet y actualizar el escáner) datos del establecimiento que lo utilizará (nombre del negocio, correo electrónico etc.) para darle un toque más personal a los reportes de diagnóstico que llegues a emitir. En mi caso tuve que actualizar el escáner seleccionando una cantidad de casillas que corresponden a diferentes marcas de vehículos y también para la función de detección automática de vehículos. Recomiendo fuertemente descargar TODAS las actualizaciones que te pide el escáner para que no te vaya a arrojar algún error al diagnosticar algún vehículo. Les comparto que en una ocasión no podía diagnosticar un Chevy Corsa y resultó que como no había descargado los datos de la marca de auto Opel, no podía acceder a los datos de ese Chevy jeje. Me tomó buen rato dar con el problema del porque el escáner no se comunicaba con el coche, pero resultó haber sido eso jeje. Una vez que hayas actualizado el escáner estarás en la pantalla principal desde donde podrás realizar varias funciones (todo esto se detalla en el manual de usuario) Entre ellas obviamente es realizar el diagnóstico completo por medio de la detección automática, realizar un escaneo normal OBDII para cuando no funcione la detección automática, consulta de diagnósticos previos y la función de checar el voltaje de la batería de tu vehículo para verificar su estado de salud. La herramienta de detección automática me funcionó en coches del 2005 en adelante donde el escáner jala automáticamente el número de serie del vehículo y te arroja el diagnóstico completo. En vehículos más antiguos solo tuve que ingresar el número de serie y dependiendo del vehículo contestar una serie de preguntas para identificar el vehículo con mayor exactitud. Como entusiasta mecánico estoy bastante contento con el escáner. He escaneado ya varios vehículos y he encontrado los datos de todos. Agrego que para los vehículos más modernos también me arroja códigos de transmisión, sistema de frenos ABS y de las bolsas de aire. Se pueden visualizar datos en tiempo real también así como consultar una biblioteca de códigos ahí mismo en el dispositivo. Sinceramente no sé que tan útil le sería a un mecánico profesional ya que carezco de conocimientos avanzados para determinar que funciones son las que necesitan y cuales salen sobrando; pero en mi caso me ha sido muy útil. Estoy muy contento con la compra. Saludos y gracias por leer mi opinión.

フィアットのチェックランプを無事に消せました。（500Ｘ） 国産車はこれからためそうと思います！

Super outil

Work perfect, quick VIN recognition, a lot of data from different vehicles onboard sensors and computers, real time diagnostic. First time after run the OBD requires a lot of updates so it will take a time. Run updates first than go to work 😁
