Complying with California’s Heavy-Duty Inspection and Maintenance (HD I/M) Regulation, also known as the Clean Truck Check, requires the use of certified On-Board Diagnostic (OBD) test devices for periodic vehicle emissions testing starting in 2024. The California Air Resources Board (CARB) has rigorously evaluated and issued Executive Orders (EO) for a range of diesel scan tool options that meet these stringent requirements. For businesses and fleet operators seeking “Diesel Scan Tool Used For Sale” to ensure compliance, this article provides a detailed overview of CARB-certified devices currently available.
Only CARB-certified OBD test devices are authorized for performing compliance tests on eligible vehicles under the Clean Truck Check program. It is crucial to procure these certified tools directly from the vendors listed below to guarantee adherence to California regulations. This list is regularly updated by CARB as more devices complete the certification process and receive an EO.
For Volvo and Mack truck operators, specific guidance is available regarding the SAE J1979-2 (OBDonUDS) Protocol. Click Here for detailed information on testing vehicles utilizing this protocol.
Below is a categorized list of CARB-certified diesel scan tools. These tools are divided into two main types: Non-Continuously Connected (NCC) devices, ideal for versatile use across multiple vehicles, and Continuously Connected (CC) devices, designed for ongoing monitoring of individual vehicles. Both categories ensure your fleet can meet the necessary emissions testing standards.
Non-Continuously Connected Diesel Scan Tools
Non-Continuously Connected (NCC) devices are scan tool-type devices designed for testing events on multiple vehicles. These versatile tools are essential for workshops and fleet managers needing to perform periodic checks across a range of diesel vehicles.

*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.
