Falcon incomplete system readiness check

My 2005 Ford Falcon with a gasoline engine is showing an incomplete system readiness check. There's an error stored and a message on the speedometer. This started after OBD2 diagnostics. Could that be the cause?

The recent OBD2 diagnostics is likely the cause. The system readiness monitors may have been reset. Have you driven the vehicle through a complete drive cycle since?

Could you elaborate on what a complete drive cycle is? I'm not familiar with the parameters.

A complete drive cycle varies, but it generally involves a cold start followed by city and highway driving to allow all system monitors to run. If the issue persists, get a professional evaluation to ensure no underlying problems exist.

Performing a standardized driving cycle resolved the issue. The system readiness check is now complete; it just needed recalibration. The repair cost was 0€, as it required just driving. Thanks for your assistance.
