98 Abs

Hi, The ABS light on my wife's 98 TS started to come on frequently. I drove it on the weekend and here is what I noticed. The light was off when I started driving. After 15 minutes in the city driving, I applied the brake and it sounded like or felt like the brake pedal had a "Click". Almost sounded like a relay is energized. The ABS light came on. Shut the engine off and restart. The light is off. Where should I start looking? Thanks

Most likely a wheel speed sensor issue, and if thats the case you will need to replace the Wheel hub assembly..

Have you had the brake system codes pulled yet?
