I had the same problem with my 2018 Ram 2500 Mega Cab, the ABS pump or the ABS control module quit working and the cruise control would not work. The problem occurred about 18 months after I bought the truck. I went online and ordered genuine MOPAR replacement parts; ABS pump and control module and did the replacement. I had to take it to an auto shop that had the soft wear to flash the module or something so that my truck recognized the new ABS module. Parts cost me about $300.00 before pandemic.
2018 Ram 2500 - my ABS / HCU just failed while the cruise was engaged on the expressway... [EDIT] 3rd HCU FAILED!!!
<UPDATE 3/29>
This is now the 3rd HCU that has apparently failed. My original failed per this thread, Ramcares expedited a replacement, which arrived dead/broken per the dealer, and the dealer to dealer part they replaced it with has now failed 9 days after closing my original case.
<original 2/21>
I own a 2018 Power Wagon and while I was on the expressway my truck had a sudden deceleration and almost got us rear-ended.
I had the cruise engaged and it unexpectedly shut off and the whole dash lit up with ABS/BRAKE warnings and a Service Electronic Braking System was displayed on the dash. It kept dinging and spamming the cluster lights every 30 seconds.
I took it to the dealer and set up an appt (they can't even look at it for 4 days and sent me driving it home - hope it is safe to drive!). I am still under my extended factory warranty, but given everything I've read on these forums, I am now expecting to be told there is a parts issue and to expect months of waiting for a replacement HCU. This could kill someone and needs to be a recall!
My question - Aside from the constant dinging, is the vehicle currently safe to drive? Aside from the TCS and ABS not functioning, is the truck otherwise safe to drive? The failed HCU/ABS module will not completely render the brakes inoperable? It will just be like driving an older truck not equipped with ABS/TCS?
Has anyone recently had the work performed? How long was your parts wait?
