Change in Beeps, Bloops, Bongs after Update for Trailer Recall

[chasc]

Seems the sounds went back to normal this morning on first start. Must be something to do with finishing the software update during operation.

I couldn’t find any official sources but I read around tonight and found some credible-sounding explanations. It implied that there was a normal controller responsible for the chime, blinker, and various alert noises but also a totally separate controller that can act like a backup in case the normal one is unavailable. It also suggested the BCM controller is responsible for managing the handoff of responsibility for audio from one to another.

The vehicle entering low power mode is frequently cited as a trigger engaging that backup audio. Presumably during the software updates something can cause it to flip to the backup audio too and it just takes a couple key cycles to get everything in normal operation again.

For those of us that have been hearing the ghost beeps, do you often have your My View settings reset to Trip 1? I’m wondering if there might be a correlation between these events and low battery conditions as noted above.
