Was drifting in a parking lot with 4x4 off, when suddenly after i came to a stop after one of the drifts, i looked at the dash to see yellow abs and dsc lights on. They quickly went off after that, and the car drove home fine.

My question is what triggers these lights? Is it when these systems are in use that triggers the lights (i.e like 4x4)?

From experience, the only time these lights have turned yellow on me is when i just got jumped from having a really dead battery.

Sorry, edit, it is the yellow brake and yellow abs lights that were flashed.
