Issue:
Toyota Sienna dash warning lights on for “VSC Off”, “Track Off” & “Check Engine” during heavy load (with 7 Large Suitcases) on highway.
Environment:
Toyota Sienna minivan
Resolution:
If you have heavy load and then dash warning lights showing “VSC Off”, “Track Off” & “Check Engine”. I would wait for few days to have it resolve itself before calling-in for service.
