WRV System Readiness Incomplete

Sounds like your car's computer hasn't completed all its self-tests since the OBD2 reading. These 'readiness monitors' check things like the exhaust system to ensure it's within acceptable emissions limits. What exactly did you read out with the OBD2? Did you clear any codes?

Thank you for your prompt response. I utilized the OBD2 reader to assess the general health of the vehicle and cleared some historical fault codes that appeared inconsequential at the time. Could this clearing of codes be the direct cause of the incomplete system readiness, and if so, what would you advise?

Yep, clearing those codes is almost certainly the reason. The system readiness monitors reset when you do that. The car needs to run through specific drive cycles to reset them, and sometimes it takes a while. It should eventually clear itself, but if you need an emissions test soon, you might want to take it to a workshop. They have tools to force the monitors to run.

I appreciate your insights immensely. I understand now that clearing the codes initiated this situation. I will monitor the system and, if necessary, consult a workshop as you suggested. However, after driving approximately 50km, the error message disappeared from the speedometer. Further inspection via OBD2 revealed that all system readiness checks are now complete. The repair cost was 0€. Thank you again for your invaluable assistance.
