How does the VDC work?
In most cases, the VDC is going to apply brakes individually at the wheels to counteract any slippage that occurs. If the vehicle is understeering, VDC applies the brakes on the outer front wheel, causing it to turn the way it should.
What does it mean when the VDC light comes on?
Vehicle Dynamic ControlIf the Vehicle Dynamic Control (VDC) OFF indicator light is illuminated on the dashboard, this is an indication that the stability control system is not engaged.

1. Faulty Wheel Sensors
Sensors are mounted to each wheel to measure their speed and performance. Any data collected by these sensors is transmitted to the ECU to be analyzed. If a wheel starts to slip, for example, causing it to turn faster than the others, the speed is transmitted to the ECU to indicate a problem.
2. Faulty Steering Angle Sensors
Any wheel connected to a traction control system will have steering angle sensors as well. These sensors are responsible for measuring the angle of the wheel as you drive. However, due to their placement, the sensors are sometimes prone to failure.
3. Bad Roads
The VDC system is designed to provide stability when a vehicle is maneuvering around slippery terrain and bad weather conditions. However, if the terrain is too harsh, the system may fall short of optimal performance.
4. Flawed Steering Rack
The steering rack is responsible for adjusting the wheels using the steering wheel’s input. It is part of the steering system and is located on the car’s body. If the rack malfunctions, the vehicle may have difficulty steering, resulting in the VDC light turning on.
5. Malfunctioning ECU
The function of the ECU is to receive instruction from the car’s computer and limit power to the affected wheel (s) accordingly whenever they start to lose traction. However, the ECU is not infallible and can malfunction.
Warnings and Common Misconception About the VDC Light

If you are driving on low-quality roads, it can also be caused by a defective ABS wheel sensor or malfunctioning steering angle sensor. It can also be caused by a defective steering rack or control module.
VDC Light Fixes
To fix the VDC light, you must first figure out what the problem is. If the light is only illuminated because of the road you are on, it should go off when travel returns to normal. This is a problem that can be fixed easily.
What does an ECU do when it senses an abnormal speed?

Broken wires. If the wires between the ABS control unit and the wheel/abs sensors are broken or just have a bad connection, it might also cause an error in the abs control module, which will light up the slip light on your dashboard.
What happens if the ABS sensor is faulty?
If the sensor is faulty, it might send the wrong information to the abs control unit, which will light up the warning slip light. 2. Faulty ABS Rings. ABS rings are also fitted out on each wheel of your car. The ABS sensors are feeling the speed from the ABS ring.
What does a slip light mean?
Slip Light – What Does It Mean & Causes. The Slip light is a component of your car’s traction control system. It helps you regain control of the car when you are driving on slippery roads. Each of the car’s four wheels has sensors that relay information to the Powertrain Control Module (PCM). When the wheel sensors notice ...
What does it mean when the ABS sensor is broken?
The ABS sensors are feeling the speed from the ABS ring. If one ring is broken, the abs sensor can feel the wrong signal and therefore send the wrong signal to the ABS control unit. 3.
