Replacing audio module Volvo V70
 

hi all:
I have a Volvo v70 2008. The car had a faulty audio module (the unit behind the waterfall console with a CD player). after replacing The audio module. the radio starts now normally but after few seconds turns off. The reason for that is the infotainment module (ICM) checks whether the integrated audio module (IAM) is on the valid list stored in the central electronic module (CEM).
I need to match the audio module with the infotainment module (ICM).
the fault code i'm getting now is u01844a.
Thank you for any idea and help.
