What Car Scanner Should I Buy? Top Picks for Advanced Diagnostics (2024)

No Comments

For car enthusiasts and DIY mechanics, a basic OBD2 code reader might suffice for simple error checks. However, when you need to delve deeper into your vehicle’s health, perform advanced diagnostics, and even carry out repairs yourself, you’ll quickly realize the limitations of entry-level tools. This is where advanced car scanners, particularly bi-directional scan tools, become indispensable. If you’re asking “What Car Scanner Should I Buy” to step up your diagnostic game without breaking the bank, the $500 to $1000 price range offers a sweet spot, providing professional-level features for serious enthusiasts and workshops alike.

Understanding Bi-Directional Scan Tools

Before diving into specific recommendations, it’s crucial to understand what sets bi-directional scan tools apart. Unlike basic code readers that only retrieve diagnostic trouble codes (DTCs) and display live data, bi-directional scanners offer two-way communication with your vehicle’s electronic control units (ECUs). This capability allows you to not only receive information from the car but also send commands to it.

What does this mean in practical terms? Bi-directional control unlocks a range of powerful diagnostic and service functions, including:

  • Active Tests: You can command specific components to activate or deactivate to verify their functionality. For example, you can cycle the A/C clutch on and off, test fuel injectors, operate cooling fans, or perform EVAP system tests directly from the scanner. This pinpoint testing helps isolate faults quickly and accurately.
  • Special Functions: Bi-directional tools often provide access to advanced service functions like:
    • Key Fob Programming: Program new keys or key fobs – a feature rarely found in scanners under $1000.
    • Module Resets and Relearns: Perform procedures like throttle position sensor relearn, idle relearn, steering angle sensor calibration, and reset adaptations after replacing components.
    • System Calibrations: Calibrate sensors and systems after repairs or component replacements.
    • Service Resets: Reset oil life monitors, service lights, and perform electronic parking brake service.

These features empower you to perform more comprehensive diagnostics, troubleshoot complex issues, and even carry out certain repairs and maintenance tasks that would otherwise require a trip to a professional mechanic.

Top Car Scanner Picks in the $500 – $1000 Range

Within the $500 to $1000 budget, you’ll find a selection of tablet-based scan tools that offer a significant leap in capability compared to cheaper options. These scanners typically boast faster processors, larger screens, more memory, and expanded bi-directional functionality. Let’s explore some of the top contenders:
