If you drive a car built after 1996, an OBD2 scanner can help you understand why the check engine light is on, read fault codes, and sometimes even fix the problem yourself. But not all scanners are the same. Some only read engine codes, while others can diagnose every module in the vehicle and run active tests.
We compared the listed specifications and features of five popular OBD2 scanners and code readers to help you find the best obd2 scanner for your skill level and budget. Each pick was chosen based on what the manufacturer states in the product listing — we have not tested any of these tools. Check each product page for current pricing, availability, and full details.
Our Picks at a Glance
We selected these five OBD2 scanners by comparing their listed specs, features, and compatibility. The picks range from a simple code reader for beginners to a professional-grade bidirectional scan tool. Prices and ratings change frequently, so check each listing for the most current information.

How to Choose
Selecting the right OBD2 scanner depends on what you want to do with it. Below are the key specs to consider, followed by a comparison table of the five picks.
Diagnostic Depth: Basic Code Reader vs. Full System Scanner
A basic code reader (like the ANCEL AD410 or VDIAGTOOL VD10) reads and clears engine-related codes and may show live data. A full-system scanner (like the MUCAR 783BT or THINKCAR 673BT) can access all vehicle modules — ABS, transmission, airbags, etc. — and often includes bidirectional controls and maintenance resets.
Bidirectional Control
Bidirectional scanners can send commands to components (e.g., turn a fuel pump on/off, retract a parking brake). This helps pinpoint faulty parts without guesswork. The Innova 5610, MUCAR 783BT, and THINKCAR 673BT all offer this feature.
Maintenance Resets
Dealer-level resets like oil reset, EPB, SAS, TPMS, and battery registration are available on the MUCAR 783BT and THINKCAR 673BT (28+ resets each). The Innova 5610 has special reset functions for re-learn procedures. The ANCEL AD410 and VDIAGTOOL VD10 do not list maintenance resets.
Screen and Interface
Larger screens (7 inches on the MUCAR 783BT) make it easier to view live data graphs. Smaller screens (2.1–3.5 inches) are more portable but may require more scrolling. Touchscreen vs. button navigation is a personal preference.
Connectivity and Updates
Some scanners require a wired connection; others offer Bluetooth or WiFi for wireless diagnostics. Lifetime free updates (MUCAR 783BT, THINKCAR 673BT) save you from subscription fees. The Innova 5610 also includes free updates. The ANCEL AD410 and VDIAGTOOL VD10 do not mention update costs.
Vehicle Compatibility
All picks work on 1996‑and‑newer OBD‑II vehicles, but coverage for newer protocols (CAN FD, DoIP) is only listed on the MUCAR 783BT and THINKCAR 673BT. Check the manufacturer’s coverage checker for specific makes and models.

FAQ
What is the difference between an OBD2 code reader and a scan tool?
A basic code reader (like the ANCEL AD410) only reads and clears engine-related diagnostic trouble codes. A scan tool (like the MUCAR 783BT) can access multiple vehicle systems, display live data, and often perform bidirectional tests and maintenance resets.
Can I use an OBD2 scanner to turn off the check engine light?
Yes, most scanners can clear fault codes and turn off the check engine light, but the underlying problem may return if not fixed. See our guide on what to do when the check engine light comes on.
Do I need a bidirectional scanner as a DIYer?
Not necessarily. A bidirectional scanner is helpful if you want to test components (fuel pump, windows, etc.) without guessing. For basic code reading and clearing, a simpler scanner works fine. Read more in our OBD2 scanner guide.
Will these scanners work on my 2024 or newer car?
Only the MUCAR 783BT and THINKCAR 673BT list support for CAN FD and DoIP protocols, which are used on many newer vehicles. The Innova 5610 states 2024 coverage is coming soon. Check the product listing for the latest compatibility information.
Choosing the best obd2 scanner comes down to the features you need and the vehicles you own. Whether you want a simple code reader for occasional use or a professional-grade diagnostic tool with bidirectional controls, the picks above cover a range of capabilities. Always verify compatibility with your specific vehicle before purchasing.
