Ashcroft ATB/3 Amigos/Traction Control Nightmare

Recently purchased Ashcroft ATB's front and rear and had them professionally installed. The 3 Amigos lights and the brake light have been on since the installation (two months or so) but the vehicle has been functioning fine. I purchased a Hawkeye Total code reader to clear the codes and it gave me a "historical" fault 4084 as well as WABCO DATA Factory Code 0115. Because it had been working fine, I just cleared the codes. Upon starting the engine, all lights were gone except the ABS light. I started to drive and the traction control light turned on and there was a grinding noise. I restarted and got the same thing. I parked and am really confused. Could the reader have somehow defaulted to some improper settings? I would be concerned about the ABS Pump/Module except it had run fine until the reader entered the picture. Spoke with someone in the UK and he thought maybe the control/ABS unit is not allowing the brakes to release.

Any ideas? Thank you for your help.

Well, I googled both codes and nothing came up. I think there should be more numbers, at least for the 4084.
The WABCO fault might be a worn out o-ring. You might need this ABS Modulator valve from R.N.

How old is your vehicle and when was the last time you had your brake fluid changed?

I have purchased an item that looks identical to that but is made by WABCO. I have not installed it yet. I am not sure on the brake fluid. Had a new engine installed a few months ago. I would really like to access the data the Hawkeye that gave me the codes before I cleared them. I will contact them and ask about accessing the history.

Did you try putting It on jack stands and spin both front and rear to determine if the issue is in the front or rear? Maybe a sensor or something was damaged in the hub or something was installed wrong and tc and/or abs was disabled until you cleared the fault that triggered them.

Flyfish, that makes a lot of sense. I will describe the procedure as I understand it. Put front axle on jack stand, put vehicle and with vehicle in neutral, spin wheels. As a shop just installed the ATBs and only after that did I have all the warning lights. The shop could have damaged something while installing the lockers. Is my description of the procedure correct? Thank you.

Basically, yes. Getting both front tires off the ground and spinning by hand and then same with the back, you would probably feel if there is a physical/mechanical issue. Sounds more likely your issue is electrical or system related, in which case everything may feel normal and sensors need to be checked out.
