Code Readers & DIY Scanners — Know What's Wrong Before You Spend a Dime at the Shop
That check engine light does not have to mean a $150 diagnostic fee at the dealer. A ThinkCar code reader tells you exactly what triggered the light, lets you clear the code if it is a one-time event, and gives you the information you need to decide whether this is a weekend fix or a shop job. Every car sold in the U.S. since 1996 has a standard OBD2 port — plug in, read, and know.
This collection covers everything from basic code readers that do one thing well to mid-range scanners that rival tools costing three times as much. Whether you are a weekend warrior changing your own brakes or a mobile mechanic building a toolkit, there is a ThinkCar scanner here that fits your budget and your skill level.

If you are not sure which scanner you need, here is the simple rule: if you just want to read and clear check engine lights, start with the ThinkOBD 20 or 100. If you want to scan ABS, airbags, and transmission too, look at the ThinkCheck M70 or ThinkScan Plus series. If you want phone-based diagnostics, the ThinkDiag Mini is hard to beat.
