On-Board Diagnostic II
OBD II is an acronym for On-Board Diagnostic II, the second generation of on-board self-diagnostic equipment requirements for light- and medium-duty California vehicles.
What is an OBD2 emissions test?
An official OBD II emissions test consists of three parts: An inspector checks to see if the MIL light comes on when the key is turned on. If the light does not come on, the vehicle fails the bulb check. If the MIL light is on and there are any OBD II codes present, the vehicle fails the test and must be repaired.
How do you pass the OBD-2 emissions test?
To pass an OBD-II emissions test, a vehicle must: If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run.
Why does my car not pass the OBD test?
When a vehicle fails an OBD emission test due to excessive OBD monitors not ready it indicates that your vehicle’s OBD system was Not Ready to perform its examination of the emission control system because the required number of monitors had not completed their analysis of the vehicle’s emission control system.
What does OBD stand for in CT emissions?
« CT Emissions OBD stands for On-Board Diagnostics. Most 1996 and newer vehicles have standardized computer systems (also known as OBDII) that continually monitor the electronic sensors of engines and emission control systems, including the catalytic converter, while the vehicle is being driven to ensure they are working as designed.
How is the OBD system used in the smog test?
Later, OBD smog test or the application of OBD system checks with OBD-I/M functionality was legalized. The primary OBD system could read, record and display error codes after monitoring the exhaust gases of each vehicle. Now, OBD systems have been expanded and are better equipped at monitoring and controlling vehicle emissions.

When does a vehicle become ” ready ” for an OBD test?
Driving the vehicle in a normal fashion may allow your vehicle’s to become “ready”. However, for certain emission systems and certain vehicles, the status returns to “ready” only after driving the vehicle a specific way. This specific “drive cycle” is determined by the manufacturer.
