Hi,
Does the vehicle have navigation? Also, what does the BAV stand for? I don't recognize it.
Let me know.

Hi,
I just figured out what BAV is. In your first post, I think you meant NAV. LOL
As far as the code U1243, I attached the diagnostics specific to it. If you take a look below, read through what is suggested and let me know if you are comfortable performing them.
Am not understanding which other harness am supposed to check as far as av. I have pulled screen out and it has a harness, what do i check as far as the av, where is it and what connects to it?

Hi,
The two codes that are stored are related. They seem to be related to the multi-function switch. See attached below. I say the switch because it is present in both codes. See pic 1
The multi-function switch ties to the front display, and the A/C control unit. I attached the wiring below.
You mean the multifunction switch on steering? That can cause this issue?

I'm looking through the schematics again and they don't specify. If that is the only AV switch, I would have to say yes.

Hi,
The schematics are vague but extremely extensive. LOL Not having things in front of me for this issue makes it extremely difficult because I can't compare what I'm seeing with what is on the vehicle. If there is an AV switch on the steering, that must be it.
