Good evening mates

I have this Volvo that has a problem that lost synchronization after battery discharge. CEM has fault in it saying about lost communication with ECU.

ECU is ESU-121 with 95040 eprom inside and CEM has 1K79X mcu inside.
Can someone please make the synchronization on this one? I haven't found it on small soft anywhere

Thanks in advance

Both eprom attached
