Enabling Pilot Assist and Adaptive Cruise Control

[BuiltInBelgium]

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.

I'll try reading DTC on an XC40 Recharge '23 with factory Pilot Assist this week before tweaking anything and see if any codes show up.
