    Today i got this infamous Check the connection of the Air Conditioner message. Seems like loose connection. If i try to turn on the display again, it works fine. I scanned with Autel and no error code (since it was working when it scanned).

    Did anyone had issue like this? All the posts i saw referring to the replacing the MFD. But all of them, was kind of dead. Not intermittent.

    This car does not like cold weather. First the P0420 which magically disappears when the weather warms up and now this.

    Seems it became permanent. All symptoms of bad connection inside.

    I tried the self test multiple times. Seems it re initiated the connection. The failure point was to the AV module communication. Shows a clear sign of communication break somewhere. Seems like a loose solder joint. Now need to buy a used one and replace it. 86110-47071 or 86110-47081 fits a 2009 base model? does any one know?

    Any of the four button MFDs should work in your base You have no backup camera or anything like that so you're good even if you use an MFD that accepts the backup camera it does not have to be there so that opens up your choices for more MFDs I have several bases with MFDs that go in well above the base vehicle with no problem they plug right up and work just fine All the buttons everything is the same
