Hey everyone I own a 2004 Volvo s60R, I started seeing the abs warning light show up on my dash very occasionally. Over the last few weeks became worse untill last week it was on continuosly.
The fault codes are as follows;
Central electrical module
CEM-1A64 AOC control module signal missing.

DEM differential ECU
DEM-E000 module communication faulty.

ABS
ABS-0100 coms with engine ECU
ABS-0094 coms with ECU, problems with active on demand
ABS-0115
Cons with steering wheel angle sensor signal missing
ABS-0148 coms between control modules faulty configuration

Battery voltage is 11.8 volts.

The ABS ECU has just come back from ECU Testing with no faults found.

There is no active suspension, no abs no traction control. I am using launch diagnostic equipment.
However I can't distinguish what's causing the issues can anyone help me please?
