I have seen a number of error messages mentioned on this forum. Check PCS, check PKSB, Check Hybrid System, etc.

Just curious how many subsystems the car is able to do self diagnostics on. Has anyone seen a list of all possible error messages from a repair manual? Item of interest is for example HVAC system. If a rock punchers the AC condenser in the winter and it loses all the refrigerant, would the system report a low pressure?

It is getting to the point that the dealer techs are relying fully on the onboard diagnostics. No warning triangle, no problem here...
