I was on the freeway going around 60 behind a car that wouldnt move out of the way. I decided to go past him so i went on a WOT and started going on his right. He then decides to change lanes to where i was at now so i had to press the brake hard. Then I accelerated past him from the left. I look to see how fast i was going and the ABS INOP light is on. I get home turn off the car then start it again. Light is off. PHEW!. What could have made the light come on?

 

My manual says it's normal.But you might check all the tail lights(third brake light especially)as they are on the same wireing as the abs(93;s anyway).
