    My 2005 Prius is still sayin “check the connection of the air conditioner” with the new MFD in the audio doesn’t work only thing work on the steering wheel is the defrosters, MAX ac button, and cruise control. I swapped out fuses that were blown and still nothing is there anything else to check for will the AMPLIFIER be the problem of this situation. My 12v Battery reads over 13v and I can’t find videos ab the MFD saying “check the connection of the air conditioner” if there’s anything else I can do plz lmk im trying everything I can rn

    best thing to do would be to check for trouble codes with a prius aware scanner, and get the 12 volt load tested

    Well, did you check the connections on the back of the MFD? If you recently swapped it, did you replace the original with an MFD that had an exact match part number? Did you connect ALL the wires on the back?

    The warning you get is identical to the warning I see on screens when bench testing an MFD that is connected only using 12v power wires, with no I/O connections made up.
