Hey there.
The issue is most likely with your radio/cd player (hard to say for sure without seeing it). There is a 6 pin connector on the radio that has 2 sets of communication wires. If you unplug the 6 pin connector on the radio, the message "Check the connection of the air conditioner" will pop up. I know this because I installed a stereo in my 2001 LS and left the 6 pin disconnected to see what would happen. The gateway ECU feeds a CAN signal to the factory radio, and then the radio connects to the multi display. If there is an issue with the radio, and the multi display cannot communicate with the gateway ECU, then this message will appear. I've attached a wiring schematic outlining what I've described above.

It makes a lot of sense.
Thank you.
I was planning to send out my original radio and amp for repair.
I’ll post the results after they are re-installed.
