How to Choose the Best OBD2 Scanner in 2024: Buyer’s Guide
Choosing the best OBD2 scanner in 2024 depends on your specific needs and technical expertise. Here are key factors to consider:
Code Reading and Clearing
The fundamental function of any OBD2 scanner is reading and clearing diagnostic trouble codes (DTCs) that trigger the check engine light. DTCs are generated by the vehicle’s computer when it detects a system malfunction in the engine, transmission, emissions, or other systems.
Clearing a code removes it and turns off the check engine light. However, if the underlying issue persists, the code and light will reappear. Clearing codes is useful for confirming recurring problems or after attempting a repair.
The Bluedriver Pro is known for its ease of use, making it ideal for those new to OBD2 scanners.
Understanding Error Codes
OBD2 codes are five characters long, following a standardized format:
- First Character: System affected (B-Body, C-Chassis, P-Powertrain, U-Undefined).
- Second Character: Code type (0-Generic, 1-Enhanced).
- Third Character: Subsystem (1-Emission Management, 2-Injector Circuit, 3-Misfire/Ignition, etc.).
- Fourth and Fifth Characters: Specific problem details.
The OBDLINK MX+ is a top-quality scanner, highly rated for its comprehensive diagnostic capabilities.
Code Reading Interface
All scanners read basic five-character codes, but user interfaces and additional code support vary. Basic scanners like the Motopower MP69033 offer simple menus for basic code reading and clearing. The Bosch 1300 OBD, while thorough, may require more steps to access codes.
Bluetooth scanners with phone apps, like Bluedriver Pro and OBDLINK MX+, provide more intuitive interfaces and often display more detailed vehicle-specific codes. Some scanners, like Ancel BD31, Bluedriver Pro, OBDLINK MX+ and Topdon TopScan OBD2 Bluetooth Scanner, can also read ABS, airbag, and TPMS codes, offering broader diagnostic coverage.
Ancel BD31 offers Bluetooth and wired connectivity, plus a HUD for live data display.
Diagnostics and Solutions
Beyond reading codes, diagnostic capabilities vary. Basic scanners like Motopower MP69033 provide only code descriptions. The Bosch 1300 OBD includes a database of 26 million fixes. Bluetooth scanners often leverage internet connectivity for broader diagnostic information and potential solutions. The Ancel BD31 stands out by suggesting multiple potential fixes and providing a Google search link for each code.
Bluetooth OBD2 scanners use smartphone apps to display data and offer enhanced features.
Live Data and Real-Time Monitoring
OBD2 scanners can display real-time data from vehicle sensors. Some show single sensor data, while others monitor multiple sensors simultaneously, presented numerically or graphically. The OBDLINK MX+ excels with a dashboard-style heads-up display, customizable gauges, and extensive data logging, including trip data. The Topdon TopScan OBDII Bluetooth Scanner offers advanced features like air-fuel mixture adjustment and compression testing.
The Bosch 1300 OBD includes multiple connectors for broad vehicle compatibility.
Ease of Use
Modern OBD2 scanners are designed for user-friendliness. Bluetooth scanners, controlled via smartphone apps, generally offer simpler and more intuitive interfaces than traditional wired scanners. The Bluedriver Pro app is particularly praised for its ease of navigation and step-by-step instructions.
Wired OBD2 scanners have built-in screens for displaying diagnostic information.
Connection Type: Wired vs. Bluetooth
OBD2 scanners connect via wired or Bluetooth connections.
Wired Scanners
Wired scanners are traditional, self-contained units with a screen and button controls. They are reliable, don’t require batteries (vehicle powered), and can store offline data like the Bosch 1300 OBD‘s fix database. However, they are less compact and require physical proximity to the OBD2 port.
Bluetooth Scanners
Bluetooth scanners are compact adapters that connect wirelessly to smartphones or tablets via an app. They offer larger, clearer displays, more user-friendly interfaces, and greater portability. However, they rely on a compatible device with a charged battery and may require internet access for full functionality.
We tested a variety of OBD2 scanners to help you find the best one for your needs in 2024.
