LAUNCH CR3001 Professional OBD2 Car Diagnostic Tool Engine Fault Code Reader
Check Engine Light
The check engine light is part of your vehicle's onboard diagnostics (OBD) system. Computers have control and monitor vehicle performance, regulating such variables as engine speed (RPM), fuel mixture, and ignition timing, and may even tell the automatic transmission when to shift.
When the electronic-control system finds a problem it cannot adjust, the computer turns on a yellow warning indicator and stores a trouble code in it's memory. These diagnostic trouble codes (DTC) help identify the probable source of the problem, such as a malfunctioning sensor or a misfiring engine and can be read with a scan tool or diagnostic computer. Vehicle manufacturers originally used the OBD system to help technicians pinpoint and troubleshoot malfunctions. Exactly what the OBD system looks for depends on the make, model and year of the vehicle.
As everybody who has cars knows, people always spend hundreds of even thousands of dollars on their vehicles just because the engine light was on.
The easiest way to reset the check engine light and clear any codes is to use a scan tool, which plugs into the OBD2 DLC port, usually somewhere on the driver’s side.
Check your owner’s manual for the location. For DIYers, you don’t need to in-vest in a top-of-the-line scan tool for basic diagnostic functions, our Launch Creader 3001 make DIYer and car enthusiatist repair their vehicle’s problem by themselves.

It performs fairly well as advertised. This is my 1st scan tool and I needed it for my own personal use to solve a check engine light issue on my 2010 Malibu that couldn't be fixed since 2017 and I used it for my powertrain control course at my community college. In the beginning, I was very new to ECM data and had no clue what to expect. Throughout the course, I was taught various types of scan tools and modes they're capable of. I eventually wanted to invest in my own scan tool so I researched on Youtube and articles. I watched Justin Dow's review and bought myself one. It's a pretty neat scan tool that I've used so far. Very easy to read and it's nicely organized how it displays the information. What bugs me about the tool is that when I scroll down too fast physically, the screen lags and doesn't keep up with the button I command it to do. It would freeze for like 3 seconds then the screen will display what I want. Another con is when I want to erase the code, I follow the instructions but then as I proceed the tool would say "Error, failure to erase code. Make sure the engine is off, ignition on." (but the engine is already off and ignition is on.) However, once I start the engine up, the check engine light will disappear, which is what I wanted. I don't know if the scan tool is haveing glitches or sort, I haven't mentioned to customer service about it. I wanted to get the name of manufacturer codes such as P1174. I couldn't obtain that type of information. So I don't know if the scan tool was not supposed to obtain that info or only if a factory level scan tool was able to obtain that info. Thank you to the team who created this helpful piece of diagnostic hardware! With the guidance of obtaining information, I was able to fix my emissions issue on my malibu.

You know the situation, where you’re driving and all of a sudden the check engine light comes on. It creates a little bit of anxiety. A little bit of fear. With this, you can keep it right in your console or your glove box and if the need should ever arise, you can always find out what it is. Or you know you always have that one coworker that’s driving around with the check engine light on and they have no idea what it’s for. This would be a great opportunity to help them out too. It’s nice and compact extremely easy to use who you are. For the price it’s real hard to beat.

This is a great obd2 scanner for the price. Simple and easy function for all makes and models. I like that it is not too small and is tethered instead of Bluetooth. It scans fast and readout is very simple to read vs more expensive and complicated models. This is not meant for complicated scanning of specific systems in cars but those obd2 scanners will run around 150.00 and up. It will read out check engine light codes and great for about 80% of any issues you might come across.

First off a bit about myself because a lot of reviews are not accurate because of the lack of knowledge. I have been a mechanic for over 30 years and have owned two diesel equipment repair businesses. Make no mistake. This is Launch of China, they are the same manufacturer that makes Launch Tech USA, but Launch Tech USA has their own software. First of all the box showed up water, damaged, and upon opening everything was extremely dirty, but it didn’t look used. Some of the components were damaged during shipping, but were in usable condition. After opening the box I noticed that the tablet was a 2020 year model, not a 2023 like the ad claimed! An account was made, the unit was charged and fully updated, and then plugged into an International Maxxforce. The unit would not connect to three different International trucks we tried and in said on the screen that “no International software was found“. The scan tool was then plugged into two different Dodge trucks, none of which preformed automatic connections, and the Vin number was entered manually. One of the trucks, the scan tool would not clear a code that my Snap-on Solus had no issue clearing. After contacting Launch of China to make them aware of the issues, they told me the unit needed to be updated. Again I performed all updates available, none of which pertained to any major heavy duty truck manufacturer or auto manufacturer for that matter. Again the unit was plugged into an International truck with the same results. After this, I looked into exactly what software was included on the scan tool, and there was absolutely no software for any major manufacturer like John Deere, caterpillar, Volvo, Hitachi, Cummins, Detroit, International , etc. NONE!!! Emailed the company twice with pictures and information to which they have not replied. A little extra kick to the teeth, in the ad it said that a free gift of a Creader 3001 and a borescope would be included free of charge and all you have to do is “add them to your cart and they would automatically include them free“. Never received the borescope, and they charged me for the Creader 3001! Thank God, Amazon was gracious enough to push a return through, even though it was past the 30 day return policy. Launch of China is not to be trusted and I will never purchase any of their products again.

Looked like a nice easy to used code reader. I am an older male. Not too computer savvy. Found the plug plugged it in and don't know if it's me or the reader. Had a hard time getting it to work. I just gave up. Took my car to o'Reilly's. Got it done. Wish I could have be able to scan my car.

Bought this 3 years ago so that we could scan our fleet vehicles in house and save on the cost of sending it to a mechanic. Works excellent with all vehicles I have used it on. Very easy to use. I bought one for myself at home
