Based on that video the o2 sensor is not telling you that it is lean. It should be switching back and forth like that. Basically the engine controller cannot keep the engine running perfectly all the time so it is constantly changing it to get it to switch between rich and lean. This means it is right on the sweet spot.
What was the actual code that you are getting and is there a reason they are saying it was running lean?
We don't have a manual on your vehicle because it is not offered here in the USA but I am sure we can try to figure this out as an engine is an engine.
