Modified Software Standards

On July 19, 2021, a modified software check was added to the BAR-OIS Smog Check inspection. Software approved through a California Air Resources Board (CARB) Executive Order should not cause a vehicle to fail for modified software.

Vehicles identified with illegally modified software will fail the Smog Check inspection. The vehicle inspection report will show Modified Software for the overall inspection result. Once the vehicle is restored to an OEM-approved or CARB-approved software configuration, the vehicle may be retested at any licensed Smog Check station, unless otherwise directed by BAR to a Referee or STAR station. Consumers seeking to dispute inspection results may contact the Smog Check Referee by calling (800) 622-7733.
