I wasn't using the MicroVAT for parasitic draw testing I was trying to check just the condition of the battery with it. It won't let me proceed with the test because it must see a draw on the battery and thinks an accessory is on which wouldn't give an accurate test.

How long did you wait before connecting it? It takes a while for everything to shut down again after opening the door to open the hood.

So, disconnect the battery and THEN check its condition.

I didn't want to disconnect the battery (even with a battery power saver plugged into OBD II connector) because I don't want to give the dealer any reason to point the finger at me and say I was the cause of any electrical component failures from spikes or whatever. The battery has never been disconnected in this car. I just thought I would check the battery with the MicroVat myself before I brought it to the dealer this Thursday. I didn't realize the MicroVAT would give me that message. If I was able to get a battery test and the results were bad battery I was going to call dealer and ask them if they wanted me to replace battery prior to my appointment. Of course if I was going to replace battery at that point I would check and see if draw was still present. Now I guess I just wait it out and bring to dealer on Thursday.

I let it sit overnight. I just connected the MicroVAT again and now it allowed me to do the battery test. The battery tested good.
