The California Air Resources Board (CARB) has mandated the use of certified On-Board Diagnostic (OBD) scan tool hardware for periodic vehicle emissions testing, starting in 2024. This requirement, outlined in Title 13, CCR, Section 2196.3(a)(1) and (2) of the Heavy-Duty Inspection and Maintenance (HD I/M) Regulation, is a critical part of the Clean Truck Check program. For vehicle owners and fleet operators in California, understanding and utilizing CARB-certified Obd Scan Tool Hardware is now essential for compliance.
This article provides a comprehensive guide to CARB-certified OBD scan tool hardware, drawing directly from CARB’s official list of approved devices. It’s designed to help you navigate the options and ensure your vehicles meet the necessary emissions testing standards for the Clean Truck Check.
Understanding CARB’s Clean Truck Check and OBD Scan Tool Hardware
California’s Clean Truck Check program is designed to ensure that heavy-duty vehicles operate cleanly and efficiently, contributing to improved air quality throughout the state. A key component of this program is the requirement for periodic OBD emissions testing. This is where CARB-certified OBD scan tool hardware comes into play. These specialized tools are designed to accurately read and interpret the diagnostic information from your vehicle’s onboard computer system, ensuring reliable and standardized emissions testing.
Only devices certified by CARB can be used for official Clean Truck Check compliance tests. Using non-certified hardware could lead to failed inspections and potential penalties. Therefore, selecting the correct, CARB-approved OBD scan tool hardware is a crucial step for vehicle owners and fleet managers.
Non-Continuously Connected OBD Scan Tool Hardware
Non-Continuously Connected (NCC) OBD scan tools are designed for versatility and use across multiple vehicles. These devices are particularly useful for garages, inspection stations, and fleet operators who need to test various trucks periodically. Here’s a breakdown of the CARB-certified NCC devices:

PT40 by Pacific Track, LLC
Pacific Track, LLC offers the PT40, a continuously connected device designed for reliable vehicle tracking and diagnostics. This device also supports both 9-pin SAE J1939 and 16-pin SAE J1979 diagnostic ports, making it a versatile option for fleet management and Clean Truck Check compliance.
V4 Series by Zonar Systems
Zonar Systems provides a wide range of V4 series devices, including V4, V4 Base, V4 Essential, and more, all certified by CARB. These continuously connected devices are designed to support the 9-pin SAE J1939 diagnostic port, catering to vehicles commonly using this protocol.
Choosing the Right OBD Scan Tool Hardware
Selecting the appropriate OBD scan tool hardware depends on your specific needs and operations. For periodic inspections of multiple vehicles, NCC devices offer flexibility and cost-effectiveness. For continuous monitoring and fleet management, CC devices provide ongoing data and streamline compliance reporting.
When choosing, consider:
- Vehicle Types: Ensure the tool supports the OBD protocols (SAE J1939 and/or SAE J1979) and connector types used by your vehicles. Vehicles with Cummins, Detroit Diesel, Navistar, or Paccar engines generally use SAE J1939, while Ford, Hino, Isuzu, and Volvo engines often use SAE J1979 (OBD II).
- Functionality: Determine if you need a basic scan tool for periodic checks or a more advanced telematics system for continuous monitoring and data analysis.
- Vendor Support: Reach out to the listed vendors to discuss your specific requirements, get detailed product information, and understand purchasing options.
Staying Compliant with CARB Regulations
Using CARB-certified OBD scan tool hardware is not just about passing inspections; it’s about contributing to cleaner air and a healthier environment in California. By choosing the right tools and staying informed about CARB’s regulations, you can ensure your vehicles meet the required standards and operate efficiently. Always refer to the official CARB website for the most up-to-date information and any changes to the certified device list. For purchasing CARB-certified OBD test devices, contact the device vendors directly to find the best solution for your vehicles and fleet needs.
