Diagnose all your vehicle's problems with this discounted Car Code Reader for $10

Making sure your vehicle is well taken care of is much easier with the right tools. One essential that everyone should have in their glove box or garage is an OBD2 scanner like the TopDon TD309 Car Code Reader (opens in new tab). It's on sale for just $9.99 at Amazon when you use promo code UNW7UAJQ during checkout, making it affordable enough where there's no excuse not to own one.

This car code reader is extremely versatile and works with most vehicles manufactured after 1996 in the US or 2000 in Europe. Simply plug it into your vehicle's OBD-II port (usually found somewhere beneath the steering wheel) and you'll be able to check on its diagnostics and clear any trouble codes showing on your vehicle's dashboard. It can read and display I/M monitor status, determine the Malfunction Indicator Lamp status, and more, and its large display makes it easy to read too.

Now you won't have to take your vehicle to a mechanic for every little thing, and you won't have to just trust that the mechanic is telling you the truth when it is time for a repair. Having one of these could even help guide you to fixing an issue all on your own so you can save time and cash. It supports various languages, including French, German, Dutch, Spanish, and English. TopDon includes a 1-year warranty with its purchase.
