OBD2 Port and Smog Checks: What You Need to Know
In many states, including California, smog checks are a mandatory part of vehicle registration, particularly for gasoline vehicles from model year 2000 and newer, and diesel vehicles from model year 1998 and newer. The OBD2 system plays a critical role in these inspections. During a smog check, a certified technician will connect a smog check analyzer to your 2006 Suzuki Aerio’s OBD2 port to assess several key aspects of your vehicle’s emission control system.
Key OBD2 Tests During a Smog Check:
-
Readiness Monitors: These are self-tests performed by your vehicle’s computer to ensure that the emission control systems are functioning correctly. Common monitors include those for the oxygen sensor, catalytic converter, evaporative system, and EGR system. For 2000 and newer gasoline vehicles, regulations typically allow only the evaporative system monitor to be incomplete. All others should be in a “ready” state to pass the OBD test. For 1998-2006 diesel vehicles, all monitors must be complete. For 2007 and newer diesels, only the Particulate Filter and NMHC monitors can be incomplete.
Model Year Fuel Type Number of Incomplete Monitors Allowed to Pass OBD Test 1996-1999 Gas Any one 2000 and newer Gas Evaporative system 1998-2006 Diesel Zero 2007 and newer Diesel Particulate Filter and Non-Methane HydroCarbon (NMHC)
Readiness monitor standards for OBD tests, outlining the allowable number of incomplete monitors based on vehicle model year and fuel type.
-
Malfunction Indicator Lamp (MIL) or “Check Engine” Light Status: The smog check will verify that the MIL is functioning correctly. It should illuminate briefly when the ignition is turned to the “key on, engine off” (KOEO) position and then turn off once the engine is started and running (KOER) if no malfunctions are detected. If the MIL is on when the engine is running, or if it doesn’t illuminate at all during the KOEO test, the vehicle will fail the OBD portion of the smog check.
Vehicle Pass/Fail Standard All with OBDII Pass MIL illuminates when key on engine off (KOEO). All with OBDII Pass MIL turns off when engine running (KOER). All with OBDII Fail MIL does not illuminate when key on engine off (KOEO). All with OBDII Fail MIL illuminates when engine running (KOER).
