ABS Actuator GEN 3 Question

Hi everyone,
I got code C1345 and C1368, tried Linear solenoid valve offset calibration multiple times with Techstream and other scanners, with battery charger attached to 12v battery, on leveled surface, but no luck. I decided to replace the ABS actuator, today got used one at u-pull-it for cheap, the problem is it has different part number than mine.
The one that I pulled from parts yard and i am planning to install is from 2013 Prius, part number: 47210-47350 EC
I own a 2011 Prius and part number for my actuator is: 4210-47310 EH
Visually they look identical, but not sure if the software or something else is different, I did my own research, some websites will show that 47210-47350 fits Prius 2010-2015, other websites will show only 2012-2015, how to know exactly if the part will fit my car or not?
Also what letters "EC", "EH" mean?
Thanks in advance.

 

47210-47310

 

Parking brake was applied for bleeding procedure and released for LSV offset calibration, I followed the instructions:
1. Reset Memory
2. Parking brake released, Ignition On/Ready Off, aux battery 14.3V connected to the charger. Car parked on levelled surface, steering wheel straight.
2. Start Learning process, it starts, lights on the dash are blinking and I can clearly hear the ABS actuator is making different sound, sometimes it will last 120 seconds and lights will stop blinking and become solid and it will set the codes, other times it will not even finish the process and stop after 40-70 second setting the codes. Basically the offset calibration fails, I don’t thing there is an easy fix, and I will have to replace the ABS actuator(assembly with brake booster and brake cylinder), but will keep the same ABS pump, I don’t have any codes for low pressure, so I assume the pump should be good.

 

In that case the learning procedure will not start and lights on the dash will not start blinking until parking brakes are released.
