In this guide, we’ll break down the main types of diagnostic tools available at JB Tools, explain their uses, and highlight top products from each category.

Why Diagnostic Tools Are Essential

Today’s vehicles are more advanced than ever before, equipped with complex computer systems and sensitive components. While that technology improves performance, safety, and efficiency, it also makes troubleshooting more challenging without the proper equipment.

Automotive diagnostic tools allow you to:

  • Detect problems before they become costly repairs.

  • Save time by pinpointing the root cause of a malfunction.

  • Access detailed information that visual inspections alone can’t reveal.

  • Maintain vehicle performance and safety standards.

Whether it’s identifying a misfire, locating a leak, or programming new sensors, diagnostic equipment is a must-have in any modern workshop.

Diagnostic Cameras

Diagnostic cameras give you a direct view into areas of a vehicle that would otherwise require disassembly. Also known as inspection cameras or borescopes, they use small cameras mounted on flexible probes to display real-time images on a screen.



Common Uses:

  • Inspecting cylinder walls and pistons.

  • Locating leaks in hoses or coolant systems.

  • Viewing wiring and electrical connectors hidden in panels.

  • Checking for corrosion or damage in tight spaces.

  2. Vehicle Compatibility:
    Ensure your tool supports the make, model, and year of vehicles you service.

  3. Functionality Needs:
    Some tools focus on basic code reading, while others offer programming, reprogramming, and advanced diagnostics.

  4. Portability vs. Shop Use:
    Handheld tools are great for mobile repairs, while larger, more complex systems may be better suited for a fixed workshop.
