(a)

A light duty gasoline vehicle that is a 1996 and newer model year or a light duty diesel vehicle that is 1997 and newer model year must meet the OBD test requirements of OAR 340-256-0355 (Emission Control System Inspection: Emissions Control Test Method for OBD Test Program). For those vehicles that cannot be OBD tested due to manufacturer defects in the vehicle, incompatibility with the OBD test equipment, or other similar manufacturing problems, the vehicle must meet the basic test requirements of OAR 340-256-0340 (Emission Control System Inspection: Light Duty Motor Vehicle and Heavy Duty Gasoline Motor Vehicle Emission Control Test Method for Basic Program), 340-256-0380 (Emission Control System Inspection: Light Duty Motor Vehicle Emission Control Test Criteria for Basic Program), and 340-256-0400 (Emission Control System Inspection: Light Duty Motor Vehicle Emission Control Standards for Basic Program) or other test criteria as determined by DEQ.

(b)

A light-duty vehicle that is 20 model years in age through 1995 model year must meet the basic test requirements of OAR 340-256-0340 (Emission Control System Inspection: Light Duty Motor Vehicle and Heavy Duty Gasoline Motor Vehicle Emission Control Test Method for Basic Program), 340-256-0380 (Emission Control System Inspection: Light Duty Motor Vehicle Emission Control Test Criteria for Basic Program), and 340-256-0400 (Emission Control System Inspection: Light Duty Motor Vehicle Emission Control Standards for Basic Program).
