HCU code after replacing master cylinder
I replaced Master cylinder and Booster (leaked fluid into booster) and then bleed my brakes. The threads on master cylinder would not screw in the bleeder fittings to bleed the master cylinder so I just flushed all the way through the brake system. Now the brake pedal is rock hard and brakes are barely working takes everything i got to stop. I hooked up a scan tool and ran the abs brake bleed but it wont bleed the front brakes. When I have the back brakes bleeder open it bleeds them even if it is telling me to bleed the front. I got a R116A-20 code which is HCU.

No one's going to be able to help you if you don't tell them what it is you're working on, make, model, year, etc..............
