Don't know an easy way to get those warnings to go out. When they are lit, your car does not have ABS, traction control, or stability systems that can be life savers. Of course, everyone drove cars for years without them and my 70 Cougar doesn't have them, but they probably account for a major part of the big reduction in US auto accident death rates in recent years.
Anyway, you could pull off the Instrument Cluster & disable the ABS light. But you'd still get the Service Stability System & Traction messages.
The pump that is running too slowly - intermittently, when the lights come on - is part of the Brake Pressure Modulator Valve (BPMV) as you know. It isn't too bad a DIY project to replace if you are so inclined. Requires car to be jacked up & left front tire taken off to get access. A Factory Service Manual (FSM) from Helm or eBay has diagrams & steps. You could get a used BPMV at a yard to save $, or buy a new one from one of our sponsors here & not pay retail. If you don't want to DIY, you could bring it to a mechanic who is willing to use your part - would not cost $1,100 that way.
Lastly, you don't need to go to a store to get your codes read, you can read them yourself from your driver's seat. See this thread:

Good luck.

Read my ordeal with the C1243 code. It may help you. I have not had the code for a few weeks since I did this write up.

I certainly hope so. I wish I could go back and edit the post, because after I realized the location of the BPMV getting at the ground on the motor itself was easy (remove FL wheel, remove forward splash guard).
However, if the issue is in the wiring buried in the harness as one of the other posters mentioned, the solution I would propose next would be to run a new ground from the BPMV post to a clean spot on the frame.
