DSC / ABS light

Hi everyone. My car was originally equipped with DSC from factory but for a reason unknown to me one of the previous owners replaced the module (without removing the hydraulic block) with an ASC module. Now i wanted to get the full DSC back so i went to a junkyard and got a DSC module and coded it to the car. However i now i have a weird issue that i didnt have before: whenever i floor it both ABS and traction control lights come on and i lose both those functions. Brake light does not come on and cruise control continues to function properly. All it takes to get those lights to turn off is turning off the ignition, waiting 20 seconds and turning it on again until you accelerate again, which will make the lights come back up. When i check the module for errors, there is only one error: Pressure sensor (precharge pump plausibility). I have already replaced the pressure sensor and tried another DSC module but the issue remains. Does this mean that the hydraulic unit is bad?
