Need some help. Warning message

[1969cruzer]

2013 lexus lx570
My alternator is dead therefore battery is struggling a bit. Alternator being replaced tomorrow.
I started up the car after replacing all front light bulbs. The warning "check 4-wheel ahc" came on the display.
Could this be due to low voltage currently? I have a 2000 mile round trip coming up on the 19th.

Thanks

I don’t know about that specifically, but I would not do anything until the alternator and perhaps the battery are replaced and then see where you are. I’ll guess everything will be fine because low voltage can cause weird things.

This error is a low voltage issue

How about continued parking sensor failure warning? Looks to be front left. Is there a reset for the system like the back up camera/ assist feature?
