The majority of vehicles on the road in California are made after the year 2000. As of 2015, the state only requires that vehicles 2000 model year or later be tested using the Onboard Diagnostic System of OBDII. It's possible to have a vehicle made on or after the year 2000 in 15 to 30 minutes.
The steps of an OBDII Smog Check are:
Physical Inspection
OBDII Smog Test
Certificate Transmitted to the Sate for vehicles that pass testing.
Model years prior to 2000 may require a more rigourous test. Since the ODBII standard was not formalized until 2000, the vehicle must be manually inspected. Testing is done on different equipment. Not all smog shops can smog check a vehicle of this age. If you have a vehicle model years 1999-96, Indio Smog has the equipment and training to smog check your vehicle.
Physical Inspection
Functional Inspection, (possibly OBDII if available)
Acceleration Simulation Mode (ASM) inspection and possibly a tail pipe inspection
Certificate if your vehicle passes.
In addtion to the tests run on a 1999-96 vehicle a 1995 and earlier vehcile may need to have an EVAP test done. The test looks for holes or leaks in the Evaporative Emissions Control System (EVAP), which manages and stores fuel vapors to prevent them from escaping into the air. As with 1999-96 vehicles, Anytime Smog & Repair is able to test vehciles in this model year range.
Physical Inspection
Funcitonal Inspection possibly including an EVAP Test
Certification sent to the DMV if your car passes.
Heavy-Duty, Sport or Specialty Cars, and Recreational Vehicles of any model year take additional time to run a smog check. This is because in many cases parts such as a cover assembly may need to be removed in order to physically inspect the vehicle. Large vehicles also require additional time to conduct the physical inspection and test due to their size.
Physical Inspection
Emissions test appropriate for model year
Certificate transmittal to the DMV for vehicles that pass.
A smog check is a test required by the state which measures the amount of airborne pollution emitted from the vehicle being teseted. Many states including California require vehicle owners to have an smog check run on their vehicles. What type of emissions test and how often you need to have your vehicle smog checked depends mainly on where you live, the type of vehicle you have and the age of the vehicle. You can find out more in our smog check information area. A smog check consists of a visual inspection, a functional test using your vehicles OBD II connection. Depending on the age of your vehicle and the type of fuel it uses you may require and Evap and tailpipe test. If you pass your smog check you will receive a certificate. Regardless of whether you pass or fail the smog station will transmit your test results to the DMV. If you pass you will be able to register your vehicle with the DMV. If you fail, you have a certain amount of time to remedy the issue and test your vehicle again.
Smog Check Visual InspectionAll vehicles will be visually inspected to verify that the required emissions control equipment and systems are identified and present and in the vehicle and that they appear properly connected. |

Smog Check Functional InspectionMost vehicles will now go through a functional test using the ODB II connection in your vehicle. Depending on your vehicles age, gross vehicle weight and fuel type additional tests may be performed such as EGR, and EVAP. |

Smog Check Tailpipe TestAs of 2015 most vehilces only require ODBII tests. These tests eliminate the tailpipe testing requirement. If your car cannot be ODBII tested then a tailpipe emission sample will be taken by the technicial. The test system will analyze the exhaust gases emitted from the tailpipe. |

Smog Check CertificateOnce the test is complete a certificate will be issued and transmitted to the DMV. The transmission currently takes place nightly and so your results may not be available until the following morning. |
