Update on this. Ended up getting the AB version of the HCU and installed it last month. The code has now returned . Could the module itself possibly be the problem? I can not find the AB version of the module anywhere

I replaced the HCU with a new HCU I purchased online from a dealer. It’s the new AB version. The module is the old one I put back on the front.The HCU comes with a new motor, pump, valves etc. It's under the little black dome on the back side.
What faults do you currently have?
I saw this after I had already purchased the new “improved” HCU.I'm guessing a few of you guys haven't watched this video,it's worth watching.
RAM ABS Code C0020-01 FIX!!! on 2017 5500
Here is a video i made to help all you Ram owners with the dreaded abs code c0022-01. This was on a 2017 ram 5500 cummings. The complaint will be abs light a...www.youtube.com
Not taking anything personal here. Reason I’m frustrated is my truck has 25k miles,almost zero rust(live in Florida), and everything looks almost new. I have pulled apart the connector and everything looks good too. I’m wondering if a bad module would have any effect on the pump? I haven’t changed that part yet since I’m unable to find one. I also just attempted the ABS bleed again and it blew the 40 amp fuse. Maybe there’s a short in the motor somewhere ?At some point in time (i.e. several ABS pumps ago) you need to realize there is something else going on here. I'm not trying to be an A-hole here or anything so don't take this wrong. But obviously there is something else wrong and you need to go further with diagnosis. I question if the part you keep replacing is even truly bad but rather is not getting the proper control signals, intermittent power feeds or grounds (bare wiring, bad connector). For example, if a wiring connector is corroded the simple act of unplugging and plugging it back in will temporarily restore the connection. But give it a few weeks or months and you lose the connection again because the corrosion comes back. If it is truly going bad something else is causing it to fail, and not that is just a bad part.
Yea I just calle ran care they opened a case for me . Dealers Ben waiting 4 mo for the parts to fix mine.they have 10 other trucks that need the same parts.I’d suggest sending a DM to RamCares, they may be able to expedite a solution for you. I had the HCU replaced on my 2018 2500 back in the spring. It was replaced with the newer part number ending in AB, they have been out there for a while now. I had contacted RamCares and they opened a case and had a new HCU at my dealer in a week- the dealer was shocked because they had trucks lined up for this part for months.
The current UAW strike will not help since it’s affecting the parts distribution centers, but you can get the ball rolling at least. RamCares may also be able to get you some goodwill in regards to cost as well, given you have replaced this multiple times already.
Yea and in 4 mo I’ll need my state inspection. Good luck with thatbRamCares may be able to expedite one for you. You should reach out to them and see. A bunch of months with malfunctioning ABS is a serious safety concern.
