edge, traction control and abs

[duck67]

I was traveling last weekend and al of a sudden the ABS (amber) light and the TRAC off symbol illuminated. I lost cruise control as well. When I shut down and restarted I got warnings for the Traction control, collision avoidance and adaptive cruise control inop. The brakes seemed a little different but still worked. The next day, I started the car and after the light test phase I had no lights. After driving I got the ABS etc on again. Anyone have any thoughts on this? Could brake booster issue be the culprit?

I would run a CCA test on the vehicle battery. An old battery, nearing its end will cause failures similar to this. (A straight voltage test is insufficient. It must be a CCA test to diagnose a modern battery properly). 

 

This is what I use (there is a less expensive version that just measures the battery, this version also checks the charging system):

But the one listed with it is cheaper and the better tester with system test going by specs and the hierarchy chart down lower.

The BA-7 costs more because it will do all the battery tests PLUS it tests the alternator, starting and charging system.
