Today while driving down the freeway, the traction control light started blinking (slippery when wet sign) and it felt like one or more of the brakes started pulsating (feeling like from the rear). The TC light immediately went back off. This happened several times during the drive home. Also noticed that when putting the 4wd selector switch into 4wd low, the TC light comes on and stays on. Immediately goes out when returned to 4wd high or 2wd. Wondering if this is a wheel sensor or something more. Any help would be greatly appreciated. Tired of throwing money at the thing. No issues when TC is manually turned off.

HELP
