The California Air Resources Board (CARB) has mandated the use of certified On-Board Diagnostic (OBD) test devices for periodic vehicle emissions testing, starting in 2024. This requirement is part of the Heavy-Duty Inspection and Maintenance (HD I/M) Regulation, specifically outlined in Title 13, California Code of Regulations (CCR), Section 2196.3(a)(1) and (2). For those involved in the Clean Truck Check program, it’s crucial to understand that only CARB-certified OBD test devices are permitted for compliance testing on eligible vehicles.
To assist vehicle owners and fleet operators in selecting the appropriate tools, CARB has issued Executive Orders (EO) for OBD test devices that meet these stringent requirements. It is important to note that this list is dynamic and will be updated as more devices undergo the certification process and receive an EO from CARB.
For businesses and individuals needing to perform Obd Tester Tests for CARB compliance, purchasing these certified devices directly from the vendors is necessary. Below is a breakdown of the CARB-certified OBD test devices, categorized by their connection type: Non-Continuously Connected and Continuously Connected.
Non-Continuously Connected OBD Testers
Non-Continuously Connected (NCC) devices are typically scan tool-type devices designed for testing multiple vehicles during specific testing events. Here is a list of CARB-certified NCC OBD testers:

Note on OBD Protocols: Heavy-duty and medium-duty vehicles commonly utilize SAE J1939 and J1979 protocols. Vehicles equipped with Cummins, Detroit Diesel, Navistar, or Paccar engines generally use the SAE J1939 connector. In contrast, vehicles with Ford, Hino, Isuzu, or Volvo engines typically employ the SAE J1979 (or OBD II) connector.
Guidance for Volvo/Mack Trucks: For specific guidance on testing Volvo/Mack trucks using the SAE J1979-2 (OBDonUDS) Protocol, please refer to this link.
For those needing to conduct OBD tester tests for the California Clean Truck Check program, ensuring you are using a CARB-certified device is paramount for compliance. Always verify the latest list of certified devices from the CARB website to stay up-to-date with any changes or additions. Contact the device vendors directly to acquire these certified OBD testers for your vehicle or fleet.
