My ABS light is on, Stability Control and traction Control problem any ideas.

First suspect, very common, the power supply to the ABS control module circuit board has come un-soldered. Traction and Stability Control function through the ABS module so those systems are impacted as well. You can install a refurbished module for many hundreds of dollars or fix it for fifty cents. There's multiple how-to write-ups on this forum (really the only differences are how people get access to solder the two wires back onto circuit board from full-on open heart surgery to laparoscopic procedures) and even at least one Youtube how-to video.
