The California Air Resources Board (CARB) sets rigorous standards for OBDII scanners used in the Clean Truck Check program. These devices must undergo a comprehensive certification process to ensure they meet regulatory requirements before receiving approval for sale and use.
CARB certification for OBDII scanners involves a detailed evaluation process. Device vendors must demonstrate that their scanners accurately interpret vehicle diagnostic data and comply with specific performance criteria. This approval process culminates in the issuance of an Executive Order (EO) by CARB, authorizing the vendor to market and utilize their device within the program.
A crucial initial step for vendors is submitting a detailed test plan to CARB for review and approval. This plan outlines the intended testing procedures and methodologies used to validate the scanner’s performance. CARB provides a Vendor Guidance Package annually, typically in the first quarter, to aid vendors in preparing their test plans and subsequent certification applications.
The application window for certification typically opens in June each year. For instance, the 2024 application period ran from June 1st to June 30th. Following application submission, CARB reviews the submitted materials, including initial validation test files. Once approved, a dedicated CARB engineer is assigned to work closely with the vendor throughout the remaining certification stages.
The certification process involves rigorous field testing on actual vehicles, requiring multiple iterations and adjustments to ensure compliance. This comprehensive evaluation often takes several months to complete. Vendors seeking more information about the Clean Truck Check OBDII scanner certification process can contact CARB via email at [email protected] with the subject line “Interested Vendor, Device Certification Inquiry” to request the previous Vendor Guidance Package. This package provides valuable insights into the requirements and procedures involved in obtaining CARB approval for OBDII scanners.
