Plan and execute test plans, document test procedure. Prepare standardized reports and presentations for CARB OBD staff review and submittal.

Gather IUMPR data for customer vehicles specifically located in California, in accordance with Title 13 CCR Section 1968.2 (j)(3). 

Reach out to the vehicle owners to identify and procure the necessary participants in the data acquisition program. Set up meetings with the vehicle owners to facilitate data acquisition, with the aim of minimizing the hassle to the vehicle owner. Travel to the vehicle owners’ locations to gather the data.  Approach OEM licensed dealerships to inform service management of ongoing data collection program and establish connections for coordinating data collection from specific vehicles while they are at the dealership for other service. Gather the standardized reported IUMPR data (obtainable via any SAE J1979 compliant tool), as well as an option to gather non-reported monitors data (obtainable through OEM specific diagnostic tool or configuration). Analyze collected data, identify and report any anomalies in the data / log files based on SAE J1978 and the 1968.2 requirements. Prepare all reports, and submit data to OEM.

EPA and CARB have adopted emission standards for motor vehicles. To show compliance with these emission standards, manufacturers must follow test procedures specified in the Code of Federal Regulations (CFR) and Code of California Regulations CCR.

CARB also develops the OBD system regulations for vehicles sold in California and certifies these OBD systems to ensure they are meeting these OBD system requirements. EPA accepts CARB OBD certification (CARB EO approval) in lieu of EPA OBD certification 

On-Board Diagnostic (OBD) systems are self-diagnostic systems incorporated into the computers of vehicles.  The OBD system monitors virtually every component that can affect the emission performance of the vehicle to ensure that the vehicle remains as clean as possible over its entire life.  If a problem with an emissions-related component is detected, the OBD system illuminates a warning lamp on the vehicle instrument panel to alert the driver.  The system will also store important information about the detected malfunction so that a repair technician can accurately find and fix the problem.  Many states currently use the OBD system as the basis for passing and failing vehicles in their inspection and maintenance programs (e.g., California’s Smog Check program). 

Additionally EPA is responsible for providing fuel economy data for the fuel economy label (or window sticker) which is affixed on all new cars and light trucks. Automakers are required to follow very specific test procedures and submit the fuel economy data to EPA for all their models each year.
