On-Board Diagnostic Testing
Newer vehicles are tested using technology that uses the vehicle's On-Board Diagnostics(OBD) computer system to diagnose operations of emissions control systems. The new test will help ensure that today's newer and low emissions vehicles, with their advanced computerized emissions controls, continue to run clean and efficiently.
The OBD test is quick and easy. The inspector connects your vehicle to the inspection computer and downloads the data. The results are printed on the Vehicle Inspection Report (VIR) which you receive at the end of the test.
