What are the requirements for my customer to get a waiver?

If their vehicle fails a retest, a vehicle owner may apply for a waiver from further testing at any Applus test station, when:
  • At least $150.00 of diagnostics and repairs were directed towards identifying and correcting the reason for the initial test failure. You need to give the customer pre-printed repair receipts with the vehicle’s license and VIN.

  • The diagnostics and any repairs were done by a current AES at an authorized repair shop.

The AES must sign the failed test report.
  • All the emission control system components are present and not tampered with.

  • You should note on repair receipts any removed or tampered emission control system components that would prevent a waiver from being issued.
  • Contact Ecology if replacing a missing or tampered emission control system component may be difficult or impose an undue burden on the customer.

How do I get a copy of a vehicles emission test?

On the main page click on the “Get test record” link at the top of the page. Then enter the VIN or the plate number.

You can print the most recent test records or view the previous test history for the vehicle. A test copy may also be obtained at an emission test station.





top

Can I sign a test report that I printed online?

Yes, you can sign an online reprint of a test report even though the format is different from a test received from an Applus test station. You must provide your name, AES number, date, and time on the test report.

Can I sign a test report that was signed earlier by an
AES at another shop?

Yes, there can be two signatures on the same emission test form. Customers that had work performed at another AES shop may add two work orders together to apply to the waiver.

Why do we test the Evaporative system and
how does the monitor affect readiness?

On 1996 and newer vehicles, the OBD2 system monitors the fuel system for fuel vapor leaks to make sure no hydrocarbons are escaping into the atmosphere.

The requirements for running the EVAP monitor vary depending on the year, make and model of your vehicle. Generally, the following requirements apply:
  • The fuel tank must be 1/4 to 3/4 full because a near empty tank or a full tank can affect the accuracy of the EVAP self-test.

  • The ambient (outside) temperature must not be too hot (above 95 degrees) or too cold (below 30 degrees) because this affects fuel volatility and the amount of vapor inside the tank.

  • The vehicle must also have sat overnight or for 8 hours or more without being driven.

  • On some vehicles, the EVAP monitor runs when the vehicle has been cruising on the highway at light throttle for at least 10 minutes.

  • All of the components in the EVAP control system must also be functioning normally. The presence of any EVAP-related fault codes will prevent the EVAP monitor from running.




top

What vehicles are tested by Two Speed Idle (TSI) instead of by OBDII?

  • All 1995 and older gasoline powered vehicles.

  • Vehicles with a GVWR over 8500 lbs.

  • Some other vehicles authorized by Ecology because of OBD testing problems.

How many “not completed” readiness monitors
cause a vehicle to fail an OBDII test?

  • 1996-2000 model years: Three or more Non Continuous Monitors with the Readiness Flags set to “not completed” will cause the vehicle to fail.

  • 2001 and newer model years: Two or more Non Continuous Monitors with the Readiness Flags set to “not completed” will cause the vehicle to fail.

Even if there are no DTCs that have commanded the MIL on, the vehicle will fail for not being ready for testing. Ignore the evaporative monitor if there are no codes present.




top

Should I clear the codes?

Generally it is best to NOT clear the codes. This erases the memory in the PCM, including stored fault codes and previous OBD monitor test results. Consequently, it may take several days (or even weeks) of driving before all of the monitors will run, allowing the vehicle to be tested. However, there are certain repair or diagnostic procedures that will require you either disconnect the battery or clear the computer. Your customer may need to acquire a trip permit from DOL if their tab is expired.




top

What is a tampered/modified vehicle?

Tampering is considered any change to the manufacturer’s design or element of design of the vehicle. This includes the removal or disabling of an emission control device or system, or making adjustments outside the manufacturer’s specifications. Tampering is a violation of both state and federal laws. Tampering laws apply to all persons in all areas.




top

Can I work on a tampered/modified vehicle?

You may perform repairs to a modified vehicle. When doing Emission Check repairs, the Authorized Emission Specialist must list on the invoice / receipt any missing or inoperative emissions control components.

You may install aftermarket devices only if they meet the original factory specifications. Look for CARB Executive Order (EO) stickers or for an obvious disclaimer such as “Not legal for street use in California.”

Advise your customer to retain paperwork or receipts for legal aftermarket devices.
Explain to the customer that the vehicle cannot qualify for a waiver without all of its emission controls in place and operational. Customers need to understand the importance of having the emission devices in place and operating at manufacturer’s specifications so that the vehicle will perform as originally intended

Kit Car – Home Built – Specialty Car Information

There are special case vehicles that may fall out of the normal realm of testing. These may include Gray market, Home Built, and Reproduction. When in doubt about how to test these vehicles, contact Ecology for assistance.




top

I recently changed locations. Should I contact Ecology?


Yes. You must contact Ecology when you change employment or locations. Your work may not count toward a waiver if work is performed at a shop in which you are not registered.

Emission Specialist Training

For both new certification and recertification, contact your Ecology representative or one of the AES instructors for more information.
