The VSC light is the "Vehicle Stability Control". The VSC system helps prevent the vehicle from slipping sideways as a result of strong front or rear wheel skid during cornering. When the VSC warning light is set, it means there is a problem somewhere in the system, and the VSC is now unavailable. Unfortunately, there is no 1-answer, "it's this..." type of answer here. There are literally dozens of parts and sensors in the system. This can be anything from a faulty Wheel Speed Sensor (one at each wheel) to a faulty Acceleration Sensor to a problem with the VSC Control Module and anything in between. At this point, the Diagnostic Trouble Codes will need to be scanned from the on-board computer. These trouble codes will point to the part or sensor that has the problem and from there, the correct repair can be made. SOME local parts stores, like AutoZone will have the correct scan-tool to read those trouble codes. If you can find a location with the correct scan-tool, they will read the codes for Free (except in California). If you cannot find a store to scan the codes, then a shop will be needed. In the meantime... it is perfectly safe to drive the vehicle. Only drawback here, is you will not have the added safety of the VSC system, so just use a little extra caution in inclement weather conditions.
