The California Air Resources Board (CARB) has mandated the use of certified On-Board Diagnostic (OBD) test devices for the Heavy-Duty Inspection and Maintenance (HD I/M) Regulation, also known as Clean Truck Check, starting in 2024. For those wondering What Hardware Obd2 Hardware Works With Tech Authority Website requirements for this program, this article provides a comprehensive guide to CARB-certified OBD-II devices. Using only CARB-certified devices is crucial for performing compliant periodic tests on eligible vehicles within the Clean Truck Check program.
To ensure your fleet complies with California’s stringent emissions testing, it’s essential to understand which OBD2 hardware meets CARB’s requirements. This guide outlines the approved devices, categorized for your convenience, and provides key information to help you make the right choice for your vehicle testing needs. For purchasing these certified devices, please contact the device vendors directly. Keep in mind that this list is dynamic, and CARB will regularly update it as more devices get certified.

*NCC means non-continuously connected; these scan tool-type devices can be used for testing events on multiple vehicles. CC means continuously connected; these are telematics devices that are assigned to one vehicle for on-going testing events.
** The most common protocols for Heavy-Duty/Medium-Duty vehicles are SAE J1939 and J1979. In general, vehicles with Cummins/Detroit Diesel/Navistar/Paccar engines are using the SAE J1939 connector, and vehicles with Ford/Hino/Isuzu/Volvo engines are using the SAE J1979 (or OBD II) connector.
Understanding OBD Protocols and Connectors for Clean Truck Check
It’s important to note the OBD protocols and connectors supported by each device to ensure compatibility with your vehicles. The most common protocols for heavy-duty and medium-duty vehicles are SAE J1939 and SAE J1979. Generally, vehicles equipped with Cummins, Detroit Diesel, Navistar, or Paccar engines typically use the 9-pin SAE J1939 connector. In contrast, vehicles with Ford, Hino, Isuzu, or Volvo engines commonly utilize the SAE J1979 (or OBD II) connector, which is a 16-pin connector. The listed certified devices are versatile, supporting both types of connectors for broad vehicle compatibility.
Ensuring Compliance with CARB Regulations
Choosing the correct CARB-certified OBD2 hardware is not just about passing inspections; it’s about contributing to cleaner air in California. By using these approved devices, fleet operators can accurately monitor vehicle emissions and maintain compliance with the Clean Truck Check program. Always verify the latest list of certified devices on the CARB website to stay updated with any changes and ensure your chosen hardware meets all regulatory requirements. Contact the listed vendors to acquire these essential tools for your fleet’s compliance and a greener future.
