That sounds like the 40amp fuse feeding the ABS unit is pitted or maybe corroded even the fuse box looking "corroded sad" giving low voltages to the the ABS brick.

Then check power, high resistances etc to your ABS brick and grounds earths (at the socket connector)
Remember you will have a <5 volt reference signal on the high speed Can-Bus

Thankyou Tuercas Viejas for the usual helpful tip
My 2017 314 CDI Sprinter has the same C011000 fault code
The only 40A fuse with “brake” in the description is Fuse No.4 Fuse Block F55/1 Brake System (delivery pump)
Is this the fuse you mean?
I’ll source a replacement 40A fuse and try to clear the error code
If this fix works I’ll let you know....and I’ll owe you a pint
