[AK Bob]

Thank you!

I hope this saves me some pain, suffering, and money.

Please keep us posted on your progress.

I found an HCU on eBay.

It was a new in-the-box Mopar's new part number (AB, not AA).

I got it in 3 days, installed it, and the light went away.

The dealer told me months before they’d get one in.

Good find.

I just had this done on a 2018 BEFORE I purchased it.

$2000 later (fixed at Hoover Ram in Summerville, SC) it was fixed.

The dealer I purchased from ate the entire cost.

Important note, this truck had 14k on the odometer, and it failed.

This has just got to be an extremely bad run of HCUs.

I might have to try this or rebuild.

I finally got around to cleaning the connector.

Unfortunately, it was squeaky clean no sand or dirt in there as I had hoped.

Thanks for the ideas, guys.

Also, was this just the pump / just the module?

Or both?

I honestly don't know which part is bad and needs replacing (computer or pump).

Shop made it sound like they came together as a whole new unit.

I’ve been seeing more and more of this problem on pages.

Unfortunately after I posted the link, that guy sold them all, but I’m sure you can find one somewhere that has them.

I’ll keep my eye out for them and will post it for you guys.

It’s not the module that the wire connector connects to.

It’s the hydraulic control unit.

You’ll have to remove the old module and put it on the new HCU.

Did you do the "ABS Brakes Bleed" procedure or bleed the system normally?

I just replaced mine on the first of the year.

Unfortunately, from what research I had done.

It seemed like most people found the issue was actually in the pump, not the electronic module.

You might want to get a second opinion before replacing the module, not the pump.

I replaced my pump, reused the abs module, and have not had an issue since.

I thought I'd post this question here instead of starting a new thread.

Sorry, OP.

I have a new controller and module, and I will replace both when I do this.

Do any of you guys know if the new controller has to be flashed or calibrated or anything of that nature to the truck?

Or is it plug-and-play?

You have to do the ABS bleed procedure.

Otherwise, you will never get the air out.

I used AlfaOBD to do the bleeding procedure, which worked great.

I did have trouble getting fluid out of the rears with my standard pump, the pedal, 5 times and hold.

I went to the old open bleeder, pushed the pedal close the bleeder, and that did the trick.
