2004 Toyota Sienna Q&A
2004 Toyota Sienna Question: What is the cause of 'VSC -track off'on the dash board ?
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. - Autohaus Lake Norman
