I have a 1997 850 Wagon that after long trips at highway speed my ABS and TRACS OFF lights come on. I know the abs is not working because I don't hear ABS control module kick in when the car starts moving. The lights will then stay on anywhere from a few days to a week. Then for no apparent reason the lights will just go off and I can again hear the control module kick in again and things are back to normal. Would anyone have an idea what's causing the problem.
Thanks...AP
