Enabling Pilot Assist and Adaptive Cruise Control

[Apansson]

It might mean the combination of configurations you are changing does not fit to the car or your car does not have the required software.

I reverted to OEM and still had the same codes. 

I initially used ACC PA level 1 with curve speed, so I tried ACC PA level 1 without curve speed but still had the same codes. 

not sure what is wrong...

I also am getting that same DTC message on my 2023 XC40 Recharge after flashing ACC/PA.    to Level 1(used presets).   I did not enable the speed curve like you did though.  

PSCM:
U112B - Interrupted Communication with Central Electronic Module (CEM)- Bus Signal / Message Failures- Missing message

I moved to Level 1 as well and still had the DTC

I have this DTC as well, but my car has ACC from factory so i havent changed anything about ACC. Don’t know if I had it before using orbit though.
