New Smog Check OBD Reference Guide

Since the implementation of On-Board Diagnostic (OBD) inspection procedures, the Bureau of Automotive Repair (BAR) has identified specific vehicles with unique OBD test issues. Specialized testing exceptions must be followed when performing Smog Checks on these “vehicles of interest” to ensure the BAR OBD Inspection System (BAR-OIS) or BAR-97 Emission Inspection System function appropriately. Accordingly, BAR has adjusted the BAR-OIS and BAR-97 software to accommodate these testing issues and has updated the Smog Check OBD Reference Guide, formerly known as Appendix J.
The Smog Check OBD Reference Guide provides information and instructions for the inspection of vehicles with known OBD testing difficulties. The guide allows inspectors to search testing information by vehicle make, year, and model to troubleshoot testing issues, including the following:

• No communication
• No OBD II
• Unset monitors
• False MIL illumination

Remember, inspectors must enter the correct vehicle identifying information (i.e., VIN, make, model, engine size, etc.) to ensure the inspection equipment applies
the appropriate test modules, vehicle exceptions, and pass/fail standards.

Smog Check OBD Reference Guide available on BAR’s
