In the world of heavy-duty truck diagnostics, the choice of the right tool can make all the difference. Coverage, functionality, efficiency with quick data acquisition of all vehicle controllers and systems, accuracy of identifying the correct diagnostic trouble codes and operational data is paramount to a technician’s ability to correctly identify issues and repair the vehicle correctly the first time. At Triad Diagnostic Solutions, we understand the significance of selecting the best diagnostic tool for your fleet or repair shop. In this comprehensive comparison, we’ll explore and evaluate four prominent brands: Jaltest, Autel, JPRO, and Texa. While each has its strengths, we’ll highlight why Jaltest emerges as the superior choice, closely followed by Autel.

Jaltest: The Epitome of Truck Diagnostics

Jaltest features Windows-based software and has coverage modules for Commercial Truck diagnostics and ADAS calibration systems, Off-Highway Equipment, Agricultural Equipment, Material Handling Equipment, and Marine Diagnostic Tools.


  1. Extensive Vehicle Coverage: Jaltest stands out with its extensive vehicle coverage, encompassing a wide range of heavy-duty trucks, buses, and commercial vehicles. Whether you’re dealing with a Volvo, Freightliner, or any other major brand, Jaltest has you covered.
  2. Advanced Diagnostics: Jaltest’s advanced diagnostic capabilities are second to none. Its precise and comprehensive scans delve deep into a vehicle’s systems, providing detailed insights and ensuring accurate issue identification.
  3. Bi-Directional Control: Jaltest empowers technicians with bi-directional control, allowing for component testing and actuation. This feature goes beyond mere diagnostics, enabling active problem-solving.
  4. ADAS Calibration Excellence: As Advanced Driver Assistance Systems (ADAS) become integral to trucks, Jaltest shines in ADAS calibration. Ensuring the precise calibration of safety features is paramount, and Jaltest excels in this critical area.
  5. Interactive Wiring Diagrams: Jaltest simplifies complex wiring systems with interactive diagrams. Whether you’re a seasoned technician or new to the field, these diagrams guide you effortlessly to the root of electrical issues.
  6. Integrated Troubleshooting and Repair Information: Jaltest features integration of both diagnostic trouble code and symptom-based troubleshooting and repair information, along with full circuit diagrams, removal and replacement instructions, OEM maintenance bulletins, and much more making it crucial for rep choice for professional repair organizations.

Autel: The Versatile Contender

Autel features proprietary Android-based tablets that cover class 2 through 8 Commercial Vehicles and ADAS calibration systems, and Off-Highway coverage for John Deere, Caterpillar, and Case.


  1. Broad Vehicle Compatibility: Autel is renowned for its wide vehicle compatibility, making it an excellent choice for fleets with diverse truck brands.

What’s more, if your tool falls out of an active Total Care Program period, you can renew your subscription through Triad Diagnostic Solutions and your Autel MaxiSYS tablet is once again eligible for all the benefits of the Total Care Program.

JPRO and Texa: Competent Options with Limitations


While JPRO has a few notable features, it tends to have limitations in terms of vehicle coverage and advanced diagnostics. It is fundamentally designed to work with OEM software on the same diagnostic laptop increasing the overall cost, complexity, and functionality of the tool. JPRO may only be as suitable for fleets with diverse vehicle brands or those requiring in-depth diagnostic capabilities if that fleet wants to continue making major investments in OEM software and ongoing support fees to manage the tool.


Texa poses a challenge regarding user-friendliness and cost-effectiveness. The learning curve can be steeper, and it may not offer the same level of versatility as Jaltest or Autel.

The Superior Choice: Jaltest with Autel as a Strong Contender

In this comparison, Jaltest emerges as the superior choice in heavy-duty truck diagnostics due to its comprehensive vehicle coverage, advanced diagnostics, bi-directional control, ADAS calibration excellence, and user-friendly interactive wiring diagrams. It is the epitome of efficiency and accuracy, ideal for repair shops and fleets.

However, Autel is a strong contender, particularly for those seeking versatility, user-friendliness, and a reliable diagnostic tool that covers a broad range of vehicles, with a smaller investment. Autel is the perfect choice for aftermarket repair organizations, smaller fleets or fleet shops, and mobile repair organizations.

While JPRO and Texa have some merit, they may have limitations regarding vehicle coverage, ease of use, and advanced diagnostics. On top of that, when holistically analyzed, they are both considered high-cost due to the need to supplement the respective software with OEM software or other tools.
