BAR On-Board Diagnostic Inspection System
The BAR On-Board Diagnostic Inspection System (BAR-OIS) is required to inspect most model-year 2000 and newer gasoline vehicles, hybrid vehicles, and alternative-fuel vehicles and most model-year 1998 and newer diesel vehicles.
The BAR-OIS consists of a certified Data Acquisition Device (DAD) and off-the-shelf equipment, including a computer, bar code scanner, and printer. The system uses the California BAR-OIS software to communicate with BAR's central database through an internet connection.
For information on BAR-OIS inspection requirements, refer to the Smog Check Manual. For information on system and equipment requirements, refer to the BAR-OIS Frequently Asked Questions page.
