Stability Control Off Indicator symbol. This light, or one of the text examples below, tell you that the stability control system is deactivated. Your vehicle manufacturer may call this AdvanceTrac, Automatic Stability Control (ASC), Dynamic Stability Control (DSC), Dynamic Stability and Traction Control (DSTC), Electronic Stability Control (ESC), Electronic Stability Program (ESP), Interactive Vehicle Dynamics (IVD), Precision Control System (PCS), StabiliTrak, Vehicle Dynamic Control (VDC), Vehicle Dynamics Control Systems (VDCS), Vehicle Stability Assist (VSA), Vehicle Stability Management (VSM), Vehicle Stability Control (VSC), etc. But the light means the same thing. The system is currently off. The vehicle will operate normally — that is, without the stability control enhancement — with the advanced system off.
Stability control is a sophisticated electronically-controlled system that uses sensors in tandem with other systems to identify when there is lateral slip in the tires during cornering and responds by adjusting the brakes, throttle, differential and/or suspension to help keep you on track. Thus, the system is automatically turned off when the Check Engine Light is activated in order to prevent inaccurate readings sending incorrect instructions to the system. The image of a skidding car is overly disconcerting.
These text symbols, or one matching one of the other acronyms, will be seen in some early model vehicles that use the system. Newer vehicles are more likely to use the picture symbol above.
Here’s a video describing when and how these lights may appear.
