V90/XC90/S90 HK AUD .VBF Files

[IMAY2023]

Interestingly enough, I have a V90 and I went from HP to HK. I got my donor HK amp from an XC60 and was able to flash it with the proper V90 configuration. All the speakers work as expected, but I still have the B1A06 and B1A08 DTCs.

Well shiieet. Effectively it will be no difference for me as i drew a wire from amp to back door tweeters, and the fault for mid rear speakers missing will still live on. ?

Hard to say. I drew new wires to both the front and rear doors. But I still had the codes.

Were you able to find a diagram that shows the speaker numbering, i.e. that speaker "6" and "8" are for the rear door mids?

No its just my guess as its the only speaker pair i dont have and cant have vs a v90. Would love a diagram with speaker numbers

The fault codes are odd. I have a V90 and could add the mids on the rear door. But I understand they are wired in parallel with the tweeters. I have the tweeters wired to the AUD, so the AUD should not be sending a DTC for open circuits for that channel/wire pair.

So all in all, knowing what the car considers to be speakers 6 & 8 would be nice.

What is the year of your car and what is the year of replaced AUD. The wiring is different.  
If your car and the replaced AUD's year before 2023.
