Steeljan, it’s been about a month since your posting with news of a $50 OBDII reader that is ED compatible.
Got any screen shots that you might share showing the 12V and HV battery condition?
And how did your visit to the dealer go with A/C service?
OBDII that works, FOUND! Electric Smart Car

It is believed that when the temperature goes above 40C (104F)…
“On vehicles with code (V03) Battery cooling system, the coolant for the high-voltage battery can additionally be cooled by the air conditioning system via a refrigerant/coolant heat exchanger (chiller).”

The electric refrigerant compressor is a high-voltage component and contains an inverter for powering a spiral compressor, which is driven by an electric motor, as well as an integrated control unit. The control unit of the electric refrigerant compressor regulates the speed of the electric motor to the value set by the heater/AC operating unit. The control unit communicates with the drive-train control unit via LIN. This only acts as a router for the CAN signals from the heater/AC operating unit in this case.
Note, the High-voltage adapter plate fuse box contains a 40 A fuse on the electric refrigerant compressor. PROCEED WITH CAUTION!
