Venza System Readiness Error After OBD2 Scan

Probably. Did you clear any codes during the scan? Sometimes that messes things up. Have you tried doing a drive cycle?

I did clear some codes. What's a 'drive cycle'? Is there a specific procedure for the Venza?

Yeah, clearing codes will do it. It's basically a set of driving conditions the car needs to see to reset everything, especially the exhaust system monitors. Figuring out the exact Toyota drive cycle can be a pain. Easier to just take it to a workshop.

Thanks! I went to the workshop. It simply needed a computer reset. No cost.
