Autel OBD2 Scanner MaxiScan MS309 Car Check Engine Code Reader, Check Emission Monitor Status, Newer CAN Diagnostic Scan Tool for All OBD II Protocol Vehicles After 1996

I've had one for about 5 years . Easy way to find trouble codes and fix your car. Just use a search engine to look up the codes and fix the car yourself.I saved thousands of dollars because I don't go to a garage or mechanic. So it takes me all day to do a 2 hour job from a shop. I save $300-$400 dollars that I don't have .Especially nowadays.Alot of fixes are simple, but mechanics and garages are greedy. A $40 part installed by you can save about $300 if a garage does it.Spark plugs, coil packs, replacing a leaking gas cap.The new one I just got is better than the older one but looks the same.I gave the old one to someone who kept borrowing mine.

I needed a scanner for a check engine light. Found a P0442 code. This scanner can erase the codes. It also tells which monitors are complete, incomplete or non-applicable. I used the scanner to verify all was well with the car before taking it for emissions inspection. Easy to use...just plug into OBD port and turn the key to on position. Well worth the money.

I have only been able to use this once on my truck. I have not had any issues with the truck and nothing showed up but it did plug right in and started right up. 2018 GMC Sierra. When the weather gets above freezing I'll try it on my niece's 2010 GMC Terrain. I'm sure something will show up on the car

Worked for me and was not too pricey. I passed inspection based off it its reading. Useful tool.

Works great. Tells you everything you need to know. Great tool. Great price. Very accurate.

Works good. I was impressed. It read the VIN so you knew it had the engine data. Confirmed the problem and gave the problem code. Also was able to clear the issue.

Work good on my car, give me accurate readings

Didn't want to spend a lot - just got bushwhacked by a mechanic. Cant count on anyone these days. Bought this- easy to use and read. Replaced the broken part myself. Car runs great. Get this and know what is wrong with your car before you take it in. Could be a $40.00 part as opposed to a $440.00 bill. Never again.

Exactly as described. Gave correct code and able to remove engine light after fix. Would recommend

Petit lecteur parfais pour petit mécano. Évidement q’il na pas les fonctions d’un scanneur professionnel mais donne les codes très facilement et efficacement. Très Facile d’utilisation.

Great little scanner. Straight forward set up. Found and erased my engine fault immediately. Good thing with the MS 309 being popular there is a whole lot of information on You Tube about how to set up and use it. Very happy with my buy.

Great little tool works perfect and very easy to use

I tested this diagnostic tool on two cars: a 2003 Toyota Echo and a 2013 Kia Sportage. Both cars were recognized with limited features. Since neither of these cars has a warning light, I can’t comment much on the functionality of this diagnostic tool. The price is reasonable.
