What action should a technician take if the Emission Inspection System (EIS) returns a "No Match" message?

• A. Verify the VIN number and plate number match the numbers on the vehicle; if they match, complete the test.
• B. Immediately abort the test.
• C. Re-enter the VIN number multiple times.
• D. Call the DMV to reissue paperwork.

Answer: (A)

When the EIS shows No Match, the first priority is to confirm the vehicle’s identity in the system by checking the numbers on the vehicle itself. Look at the VIN and the plate and compare them with the numbers you entered in the EIS. If those numbers match the vehicle, you can go ahead and complete the test—the No Match was due to a data-entry or record discrepancy, not a problem with the vehicle or the test itself. If the numbers don’t align, you need to correct the entries or resolve the mismatch before proceeding. The other options don’t address verifying that the correct vehicle is being tested.
