OBD Test Devices
Contact
The California Air Resources Board (CARB) has issued Executive Orders (EO) for the following devices that meet the requirements for periodic On-Board Diagnostic (OBD) vehicle emissions testing starting in 2024 as specified in Title 13, California Code of Regulations (CCR), Section 2196.3(a)(1) and (2) of the Heavy-Duty Inspection and Maintenance (HD I/M) Regulation. Only CARB-certified OBD test devices can be used when performing periodic compliance tests on eligible vehicles for Clean Truck Check.
Please reach out directly to device vendors to purchase CARB-certified OBD test devices for your vehicles/fleet. This list is subject to change and CARB will include additional certified test devices when vendors complete the certification process and are issued an EO for their device.

*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.
