A dealer and some mechanics can re-flash the computer if that is what you mean.

Or if you recently had your Nissan repaired and the computer cleared as part of the repair you failed because the readiness monitors have not reset yet. Keep your gas tank between 3/4 and 1/4 full. No more and no less. Then just drive normally for a few days. You can have 1, but only 1, of the readiness monitors not set and you'll still pass inspection. My '00 Grand Prix reset all but the EVAP system readiness monitor in 1 hour of driving. I just had to get it inspected and of course one of the coil packs quit creating a misfire code. After I fixed it I had to clear the computer. This also clears the readiness monitors. HTH. -Jim

The California Emissions test does not test tailpipe emissions but reads the computer instead.

NJ is that way too for OBD II (1996 and newer) vehicles. That's when they check the readiness monitors, check for trouble codes, command the check engine light on for testing purposes, and test the gas cap if the EVAP system readiness monitor is not set. HTH. -Jim
