What does VSC Trac mean?
VSC Trac light keeps showing on our 4 runner 2001 dash board. Kindly tell us what this means. Is it danger sign?
vsc is (vehicle stability control) and traction control. Do you have ABS or ANTI-LOCK or BRAKE light on too? All these are connected together and use mostly the same computer and sensors. It is nothing to panic about but you should have it looked at. This is a safety system on the car to prevent loss of control in slippery conditions or in the event of a tire blow out or evasive maneuver. Typically a speed sensor is a cause of the light, a week battery has been known to turn the light on dues to low voltage at start up. Also, make sure your not driving around on a flat tire. PS My 1998 4runner Limited has 281,000 miles and still drives like new. I like to brag about it.
