Lexus LX System Readiness Incomplete After OBD2 Use

My 2011 Lexus LX with a gasoline engine has an incomplete system readiness check, an error stored in memory, and a speedometer error message. I recently used an OBD2 diagnostics tool at 142687 km. Any ideas before I book an inspection?

I have a similar Lexus LX, and I experienced something similar after using an OBD2 scanner. Have you checked the I/M monitors to see which ones are not ready? This happened when performing car diagnostics. The check engine light was on.

Thank you for your response. I have not checked the I/M monitors specifically. Could you elaborate on how you addressed this issue, and whether it is linked to the onboard diagnostics?

In my case, the monitors eventually reset after driving for a few days, but I recommend consulting a workshop. It could be a minor hiccup due to the OBD readiness, or there could be an underlying problem.

Thank you, I appreciate your input. It seems the issue has indeed resolved itself after a few days of driving. The system readiness check is now complete, and the error message is gone. No repair cost was needed. I will keep an eye on it.
