LAUNCHOBD2 Scanner CR319 Check Engine Code Reader with Full OBD2 Functions

Nice little scan tool....Saved me a BUNCH of $$ because I was able to diagnose a bad sensor in a 2010 GMC Acadia and clear the check engine light. HOORAY!!! It's a cheap item and works for basic CEL diagnostics. And DEFINITELY worth the money!!! Only slightly negative thing is that the Screen resolution isnt awesome, but it is clear and easy to read. Super great to have around!!!

This is a very good scanner. I have couple OBD2 scanner which requires laptop. One requires serial port which non of my current laptop has. Another need USB to Serial cable which also needs driver which is very finicky. This LAUNCH OBD2 Scanner CR319 Scan Tool is awesome because it is standalone i.e.; it does not need any outside connection to the laptop. It does not require any battery either. It is very easy to use. Just plug it on the OBD2 port. Another big plus with this scanner is that the button is big. When you are working on your car with the gloves on, it is easy to use without removing gloves. If you work on your car, or want to know what is wrong with it, buy this scanner. It may pay for itself on the first time when you have to take your car somewhere.My car requires oil change on every 10k miles. After 5K miles, maintenance light comes on. When I take my car in every 5K miles in which time, they just inspect the car and reset the maintenance light, it cost more than this scanner. It pay itself when I do not have to take my car to the dealer.

Easy to use, and it will read out codes, but only if someone else hasn't erased them. If they are erased by a mechanic, and they do not reset on their own, you need to drive for about 50 to 100 miles before they come back. But in average, its a good little tool scanner just to tell you the basics. It's not the $5,000. Scanner that Scotty Kilmer uses, but it worth a few dollars for me cause I hate to get scammed and there's plenty out there scamming us!

Don't you just hate it when you check engine light goes on and you have to take it to the dealer or mechanic, or auto parts store to read codes? Well this little neat reader is so awesome, it saves you a trip to those places and it packs a ton of information...most of which I don't even know how to use. I just want to read codes and reset the check engine light..this does that and then some.On a recent 2500 trip my truck started acting funny. I read the codes with this reader...it said P0303 which is cylinder 3 misfire. That led to checking for spark in cyl 3, then wires and then distributor box...$250 part but well worth it...without this tool, I was dead in the water and at the mercy of the local mechanic "GEORGE'S"..ouch!!!Folks, get this reader and save yourself lots of headaches, let alone $$'sPS, I am not very mechanically inclined...but I do know how to change an alternator, oil changes etc.

Used for my 2016 Nissan rogue to clear and read codes. Works great

Recently I had my check engine light come on and had to go around to various auto shops to use their scanners to evaluate the problem. It appears the code was my gas cap. This was the second time this light came on, the first time the light went out on its own. I have a 2007 RAV4 4WD with 263,000 miles on it and it still runs like it’s new!!! When I went to the Toyota dealership the service mgr said for me to invest in my own scanner, they’re only $20. After much research I bought this scanner and used it the second I got it and I have no codes that came up, so the gas cap appears to have been the problem. I am planning on driving with this Launch CR319 in my car from now on as a safety measure and would highly recommend this scanner to others for its very reasonable price and accuracy.

It work OK. Wouldn't use it on an everyday use. A little hard too read and understand.
