Sienna 2004 LE was 'smoking' and had piston rings replaced. Since then 'VSC-Track off'would come on the dashboard especially after driving long distance. thanks.
What is the cause of 'VSC -track off'on the dash board ? on 2004 Toyota Sienna
It means that one of the on-board computers related to the Traction Control (either engine computer or ABS computer) is seeing a fault and therefore disabling traction. Since you just had engine work done, something may have been left unplugged. Your best bet is to have the vehicle scanned for stored fault codes.
