Trafic OBD Readiness Reset

My 2004 Renault Trafic diesel is throwing a 'System readiness check incomplete' error. Mileage is at 236615 km. The error's stored, and I get an error message on the speedometer. This popped up after I used an OBD2 reader. Could that be it? What does drive cycle mean?

A 2004 Renault Trafic diesel displayed a 'System readiness check incomplete' error after using an OBD2 reader, likely due to clearing codes. This error indicates that the onboard diagnostics system hasn't completed its tests. The solution involved performing a specific drive cycle to reset the OBD readiness, resolving the issue without repair costs.

I had something similar on my Trafic. Was it after you cleared codes or did a scan? The onboard diagnostics system needs to run all its tests before it's 'ready' for inspection. Did you try driving it for a bit?

I did clear some codes after a scan. So, this drive cycle thing - is it some kind of magic? How long is 'a bit', and what kind of driving are we talking about?

It's not magic, more like a checklist the van needs to complete. I never figured out the exact sequence. If it persists, and you need to get the vehicle inspected, you will have to go to the workshop.

You were spot on. It just needed a specific drive cycle to reset the OBD readiness. After driving as suggested, it was gone. No repair cost!
