Car is focus 2006 1.8 TDCI KKDA engine code, ecu by autodata is SID202

Actually , keys are ok in dash, but stored DTC in engine ecu and after delete dtc car start
I didnt make snbapshot from actual errors and just erased and car starts, but after that I have those errors in ecu engine (but car start ok)
U0423-E1
Invalid data received from Instrument panel control module
ane pending DTC
U0422
Invalid data received from Body Control Module

In Instrument cluster was those errors:
