I HAVE OWNED A 2002 TOYOTA SEQUOIA SINCE 2006. THIS PROBLEM BEGAN OCCURRING IN THE WINTER OF 2007 WITH THE VSC, VSC TRAC, AND ABS WARNING LIGHTS ALL COMING ON. THIS KEPT CONTINUING ANYTIME I WAS DRIVING IN WET SNOWY CONDITIONS. I BEGAN TO RESEARCH THIS PROBLEM ON LINE AND IT SEEMS THERE ARE MANY CASES OF THIS ON 2001-2003 TOYOTA SEQUOIAS. I TOOK IT TO A DEALER AND THEY COULDN'T FIND ANY COMPUTER CODES RELATING TO THIS ISSUE. AT THE END OF LAST WINTER THE PROBLEM SEEMED TO BECOME WORSE. EVEN IN DRY CONDITIONS ON DRY PAVEMENT THE VSC COMPUTER BEGINS TO TAKE OVER ACCELERATION AND VERY OFTEN! AND SOMETIMES THE LIGHTS COME ON AND SOMETIMES NOT. AGAIN I RESEARCHED AND FOUND THERE TO BE A TOYOTA RECALL ON 2003 SEQUOIAS ONLY FOR THE SAME PROBLEM THAT HAS BEEN AFFECTING MY SEQUOIA! I CALLED TOYOTA, THEY GAVE ME A CASE # AND TOLD ME TO TAKE IT IN TO THE DEALER. I TOOK IT BACK TO A TOYOTA DEALER AND AGAIN THEY COULD NOT DUPLICATE THE LIGHTS TURNING ON OR FIND ANY COMPUTER CODES CONCERNING THE PROBLEM. THAT WAS APPROXIMATELY 5 MONTHS AGO AND STILL THE PROBLEM PERSISTS LEADING UP TO YESTERDAYS ACCIDENT. I DROVE UP TO THE MOUNTAINS TO GO SNOWBOARDING. WHEN WE LEFT THE RESORT IT WAS SNOWING VERY HEAVY. I NOTICED THE ABS, VSC, AND VSC TRAC LIGHTS COME ON AGAIN, AS I WAS EXPECTING THEM TO. WE DROVE ABOUT 7 MILES DOWN THE ROAD THEN I WAS MOVING IN TO THE LEFT TURNING LANE OF A TRAFFIC LIGHT. OUR SPEED WAS ONLY 15-20 MPH, AND WHEN I TRIED TO SLOW DOWN THE WHEELS LOCKED UP AND WE BEGAN SLIDING.
