Not supported means that component doesn't apply to your vehicle. Heated O2- Try driving at steady speed (cruise control) on highway for 10 miles or so , and then coast downs (not braking) as much as safe in driving conditions. Each manufacturer has their own rec. , but that routine has worked pretty well for me on most. BE PATIENT , all cars react differently and individual driving styles can have a big effect on setting the readiness codes.
Thank you ziptie for your help. Will use your advice.
