If the Emission Inspection System initially indicates a No Match, and the VIN and plate numbers on the vehicle match the records, what should the technician do next?

• A. Abort the test.
• B. Recheck the paperwork.
• C. Complete the test.
• D. Ignore the No Match message.

Answer: (C)

The important idea is confirming the vehicle’s identity before running the test. If the VIN and plate on the vehicle match the records, the vehicle is correctly identified, so you should proceed to complete the test. The No Match warning is a signal to verify identity; once identity is confirmed, you can finish the test and finalize the inspection to capture the emissions data. Aborting isn’t needed when the identity check passes, rechecking paperwork isn’t necessary, and ignoring the No Match could leave a data discrepancy unresolved, so go ahead and complete the test and note the No Match as required by procedure.
