Default Service brake system

Have abs and red brake light on dash on and service brake system on the dic. Comes on as soon as the key is turned on and doesn't go off unless I clear abs codes- there are no abs codes in it though. This started a couple days ago when I had an engine dying issue, had a fault P2510, ended up finding underhood fuse panel corroded. Replaced fuse panel and fixed the dying issue, abs issue still present. I have cleaned the ebcm ground wire, checked voltage at ebcm connector, checked abs faults-none. Not sure where to go next, possibly have the ebcm reprogrammed?

I remember seeing something about resoldering the abs module on the frame and under the driver side. No other codes ?

No faults. I have read some of those posts, seemed like most of them were intermittent in the lights coming on, mine is on all the time as soon as the key is turned on. I may tear it apart and check anyways.

Issue seems to have went away. Cleared the lights and drove it the other day, stayed off the whole time. Lights came back on with the next start and then went off after driving about 1/4 mile. Have not came back on since, not sure why.
