ABS code as the 0057 is also known for volvo as the BCM code .

BCM-0057 Power supply. Voltage too low.

We find that the problem lies with in the BCM module, But could be as we also see after water ingress on the wiring harness

the connection are bad and need cleaning with contact cleaner also on the CEM check connections and clean .

You will have to replace the BCM module and have it updated with the new software .
