Last weekend, I had to brake hard on the road and that's when I realized that the ABS was not working (no pulsing). The ABS light on the dash is off before I start and after I start the car. I searched the forum and most of the posts were for the light being on. Any ideas where to begin to troubleshoot? This is for a 1990 190e 2.6. Thanks!
