Readiness bits in basic settings will pass (xxxx x100), but it doesn't record that to the readiness menu. Checking readiness with my handheld Autel also says it's not ready.
Car was in a while ago for emissions repairs, readiness was set then, but had faults. First autoscan.
After repairs were done, faults were cleared and they drove it over 200 miles.
200 miles later and a failed emissions test:
I've tried two ECU's and two others that we had that had a MIL circuit fault, but obviously wouldn't pass with the CEL on.
Both ECU's do the exact same thing, will pass readiness at basic settings, but it doesn't record that it's been set.
Am I still chasing an ECU issue?
I have a feeling I've dealt with this before, but can't remember the result.
I also have three other autoscans of the vehicle dating back to 2011, all with different faults and all had the readiness set when it came in the next time with new faults.
