Hard to Find Emission Parts Locator Service
The Referee offers a Hard to Find Emission Parts Loca
tor Service to assist consumers whose vehicles fail Smog Check inspections because of missing or modified emission-related parts that are difficult to find.
The vehicle may be eligible for a Limited Parts Exemption if the Referee confirms the part is not available. Consumers requesting a Limited Parts Exemption must have their vehicle inspected by a Referee Center.
The Hard to Find Emissions Parts Locator Service can be reached at (800) 622-7733.
Vehicle Design Issues Affecting the Ability to Inspect
The Referee can help consumers with vehicles that are too large to enter a Smog Check facility, or too wide or heavy to fit on a dynamometer.
Vehicles with Emission Control Configuration Issues
Referees can also assist consumers with vehicles that have difficulties passing a Smog Check inspection due to unusual emission control component configurations.
Vehicles Modified for use by Disabled Drivers
Consumers with vehicles that have been modified for use by individuals with disabilities and are incompatible with the Accelerated Simulation Mode Emission Inspection (ASM) test may be referred to a Referee Center for a Smog Check inspection. Vehicle modifications in this category include:
- wheel chair retrofitting
- steering and braking controlled by a single mechanism
- retrofitted steering with hydraulic assist beyond the vehicle’s OEM power steering
- retrofitting to allow driving with one or no hands
Vehicles that fall into this category should receive a Two Speed Idle (TSI) Smog Check inspection.
Vehicles with Alternative Fuel Conversion Kits
Vehicles converted to run on alternative fuels are required to receive a Referee inspection. The Referee will inspect the vehicle to ensure the conversion has been properly performed and the components have been approved by the California Air Resources Board (ARB).
Engine Change Vehicles
An engine change is the installation of an engine in a vehicle that is different from the one originally installed in the vehicle. A Referee inspection is required for all vehicles that have had an engine change.
Replacement of a vehicle’s engine with the same engine size or an engine offered by the manufacturer for that year, make and model is considered an engine replacement and does not require a Referee inspection.
Grey Market Vehicles
Vehicles imported into California that are not built to US and California emission standards are classified as Grey Market vehicles and require an inspection at a Referee Center.
Some import vehicles built to US and California emission standards have an underhood emission label that does not indicate the vehicle conforms to US and California specifications. Check with the vehicle manufacturer to obtain documentation stating the vehicle is, or is not, built to US and California emission specifications before receiving a Referee inspection.
Specially Constructed Vehicles (SPCNS)
A SPCNS is a vehicle which is built for private use, not for resale, and is not constructed by a licensed manufacturer or remanufacturer.
Since SPCNS vehicles do not have a manufacturer-assigned model-year, they must be initially inspected by a State-authorized Referee before DMV will issue a registration.
SPCNS vehicles must pass an inspection at a Referee Center before DMV will issue a registration.
Law Enforcement Citations for Tampered Emission Control Systems
Law enforcement may require consumers to clear a citation for tampered emission control systems at the Referee Center. In these cases, the vehicle must pass a Smog Check before the citation can be cleared. All Smog Check provisions apply when testing a vehicle for clearance of a citation.
Law Enforcement Citations for Excessive Vehicle Exhaust Noise
Referee Centers test exhaust system sound levels for vehicles that have been cited by law enforcement authorities for excessive noise. The Referee will use a decibel level meter to test exhaust system sound levels for the vehicle.
Verification of Smog Check Exempt Vehicles
Occasionally, DMV registration renewal notices incorrectly require a Smog Check inspection on vehicles exempt from inspection. Referee Centers will inspect these vehicles to verify exemptions and issue Exempt Certificates.
