No disconnecting the DEM will bring up lots of DTC's because the DEM is missing from the system.
If you have a ABS-0094 then it will be the DEM that's failed, most probably due to water ingress , its a known problem.
If it was corrosion on the CEM then you would have lots more DTC's for other systems, when my CEM got wet I had just about every warning light on the dash and even after drying it out I still had lots of DTC's until it took it out and cleaned the circuit boards.
