Answer: In addition to an analysis of tailpipe emissions, a Smog Check inspection includes a visual and functional test of required emission control systems. Since the OBD II system involves the automated self-monitoring of a vehicle’s emission control systems, the U.S. Environmental Protection Agency (USEPA) has required states to include an OBD II system test as part of the Smog inspection.

How do readiness monitors relate to the Smog Check Program?

Answer: Part of California’s Smog Check program uses the vehicle’s on-board computer to determine if the vehicle is in proper working order. To make that determination, the on-board computer must complete various checks of its emission control systems. If the checks have not been completed, there may be a malfunction that the on-board computer has not yet detected. Once a malfunction is detected, the “Check Engine” light comes on inside the car to alert the driver there is a problem that is affecting the vehicle’s emissions. Early detection of minor problems, followed by timely repair, can often prevent more costly damage to components such as the catalytic converter.

The Smog Test technician told me my vehicle was not ready to test because too many readiness monitors were reporting the systems checks had not been completed. What does this mean?

Answer: In order for the OBD system to clear the readiness monitors and complete its self-diagnostic checks, the vehicle must be driven under a variety of normal operating conditions. All of the self-diagnostic checks have not been completed if one or more readiness monitors read “not complete.” A number of factors, including emission repair work or a disconnected battery, can result in readiness monitors being set to “not complete.” In most cases, the readiness monitors can reset to “complete” very quickly, but in some cases, a few days of normal driving will be needed to do so.

My vehicle was not ready to test because too many readiness monitors were not completed and my registration is due today. What should I do?

Answer: You can go to DMV, pay your registration renewal fees on time to avoid any late fees from being assessed, and apply for a temporary operating permit. Once your vehicle passes its Smog Check, you can complete the registration process and receive your license plate tags.
