Hey,

Occasionally while driving I will get a message "Normal cruise control active. Adaptive braking off" pop up on the display. This usually goes away immediately and I can continue using adaptive cruise control.

Looking at PTS I noticed that around those times I get a DTC related to my ABS module:
- U023A : 00 Lost Communication With Image Processing Module A

The DTC clears itself eventually,, or I can clear it with Forscan and it doesn't come back until another random time.

I also noticed that every time I run the ABS self test in Forscan, I end up with 2 DTCs in the ABS:
U023A:00 and U0140:00
Lost Communication With Image Processing Module A
Lost Communication With Body Control Module

Are those two issues (the occasional "Normal cruise control..." meesage, and the DTCs after self-test), indicative of a bad ABS module?
