The inspection process will only check for systems that were installed on the vehicle by the vehicle manufacturer. For more detailed specifications for your vehicle, visit a local dealership or repair shop. Again, only those systems that were originally installed by the factory are required and inspected. Vehicles may fail due to visible smoke emitting from the tailpipe or crankcase. The color of the smoke can help determine the problem with the vehicle.
Blue smoke can indicate engine oil being burned in the combustion chamber.
Visible smoke failures MUST be corrected. A waiver cannot be issued for a visible smoke failure . Invalid rpm readings may indicate that the vehicle is idling at an excessively high or low engine speed or is unable to maintain a stable rpm within a required range. These problems must be corrected before a complete inspection can be performed on the vehicle.
