Lafesta System Readiness Incomplete

I've got a 2009 Nissan Lafesta with a gasoline engine and only 48166 km. The system readiness check is incomplete. There's a fault stored, and a message on the speedometer. This happened after reading the car via OBD2. Anyone seen this before?

The 2009 Nissan Lafesta experienced an incomplete system readiness check after using an OBD2 scanner, resulting in a fault message on the speedometer. This issue may arise if the onboard diagnostics haven't completed a full cycle, potentially due to a minor glitch. Suggested solutions include performing specific drive cycles or consulting a workshop to reset the system using professional diagnostic tools, which is often a quick and cost-effective fix.

Did this summary help you solve your problem?

I have a Lafesta and had a similar issue. It can happen if the onboard diagnostics didn't run a complete cycle. Did this occur after a repair or inspection, especially involving the exhaust system? Are there particular drive cycles that might help?

It happened right after I plugged in an OBD2 scanner to check for error codes. Are you suggesting that driving under specific conditions might get the system to complete its readiness checks? Or could something have been corrupted during the diagnostic read, requiring a more invasive approach? Should I bring it to a workshop?

Yes, that mirrors my experience. A drive cycle sometimes helps, but my issue persisted. It turned out to be a minor glitch that only a professional diagnostic tool could reset. I suggest consulting with a workshop to connect diagnostic equipment and reset the system. It may be the quickest solution, plus it's usually not too expensive.

Thanks for the insight. A trip to the workshop seems best. So the saga concludes with a system reset, costing me nothing. Thanks again!
