ABS Actuator Master Cylinder Assembly Replacement Problem

I purchased a 2013 Prius C recently with a known Braking System issue. When I purchased the car I could hear some light hissing coming from under the driver side dash and the booster kept regenerating every 15 minutes. The car was priced for the problem so I purchased it.

I thought to start with buying a used Master Cylinder Assembly from the junkyard but first I went to Toyota to get a part number. Toyota said my VIN needed the 47050-52040 because the car came with 16" wheels. The only used MCA I could find was a 47050-52020, which is for 15" wheels. I was going to change the wheels to 15s anyways because they have a better ride and longer life, so I purchased it assuming I could program it for use.

I removed the original MCA and installed the used 47050-52020. The every 15 second ABS pump sound is now gone but my Xtool D8S scanner gave me two codes C1203 Communication Circuit of ECM and C1345 Linear Solenoid Value Offset Learning Value Undone.

I started by clearing or resetting the calibration memory for the new MCA. Then Google Gemini said to select ECU Replacement or ECU Communication Reset in the Xtools scanner. I wasn't able to find this in the menu so I went on to the next step (Fix C1345 (Linear Valve Offset Learning). The scanner bled each wheels brakes but the front right didn't behave like the others. When depressing the brake pedal and holding it down, the other wheels brake bleeders would continuously push out brake fluid. The FR bleeder would only push out brake fluid if the brake pedal was pumped.

Then, in the last part of the of the Linear Valve Offset Learning was the Stroke Simulator. I hooked up a tube to the bleeder on the MCA, opened it up, and ran the program. I could hear the MCA making noise but no brake fluid came out.

At this point I'm assuming the used MCA I purchased is either bad or doesn't work with my car. I can't get those codes cleared and the issues with bleeding the MCA has me concerned.

Any thoughts?
