SOLD 2001 Dodge 3500 4x4 Expedition vehicle with 5.9 cummins and 5 speed manual

[1cambo]

When I purchased it, there was a check engine for a heater pump relay. I swapped that out and had no other issues with check engine lights. I am uncertain of why the ABS and Brake light stay on. I have had mechanics try to figure it out. But they are were not able to figure it out.

often times the rear abs sensor causes this, does the cruise work?
