At the station
What to expect at a Brookfield emissions testing station
Most stations in Brookfield perform an OBD-II diagnostic scan as the core of the inspection. The test typically takes 15 to 30 minutes if there is no line. The inspector connects a scan tool to your vehicle's OBD-II port, reads stored trouble codes, checks that readiness monitors have completed their drive cycles, and verifies that your check engine light is off.
Some older vehicles, typically those made before 1996, may require a tailpipe measurement or a visual inspection of emissions components such as the catalytic converter and gas cap. The inspector will let you know which tests apply to your vehicle's year and fuel type.
You will receive a vehicle inspection report at the end of the test. A passing result is sent electronically to the Wisconsin DNR. If your vehicle fails, the report will list the reason so you can have repairs made before retesting.
Preparation
How to prepare for your emissions testing in Brookfield
Drive your vehicle for at least 15 to 20 minutes before arriving at the station. This warms up the engine and catalytic converter and helps readiness monitors complete their cycles. Highway driving at consistent speeds is more effective than stop-and-go city traffic for completing readiness cycles.
Do not clear diagnostic trouble codes or disconnect your battery in the days before your test. Cleared codes reset readiness monitors and will cause a rejection even if nothing is mechanically wrong with your vehicle.
Make sure your check engine light is off. A lit check engine light is an automatic failure in every OBD-II emissions program. If the light is on, have the issue diagnosed and repaired before scheduling your test.
Check that your gas cap seals properly. A loose or cracked gas cap is one of the most common and least expensive reasons for a failed evaporative emissions test. Bring your current registration or any renewal notice you have received. Some stations may also ask for your vehicle identification number.
