Vehicle Dynamic Control (VDC) is a stability control technology found in both Nissan and Infiniti vehicles that works similarly to most electronic stability control systems. It gently assists the car’s ability to stay on the driver’s desired course by using a variety of sensors to monitor driver inputs and vehicle motion.
The VDC in Nissan and Infiniti vehicles aids in regulating and limiting understeer and oversteer. As was already mentioned, an understeering car reacts less quickly than desired to inputs to turn right or left. It instead moves ahead.
In contrast, an oversteering vehicle turns faster than intended, giving the driver the sensation that the vehicle’s back end is spinning. Uncorrected oversteer will cause the car to spin.
The Nissan/Infiniti VDC system modulates brake pressure to specific wheels and engine power to counteract these undesirable behaviors, assisting the driver in maintaining control of the car in both understeer and oversteer circumstances. It employs brake pressure to transmit power to a non-slipping drive wheel on the same axle to prevent wheel slip on a drive wheel that is losing traction in order to preserve overall stability while you drive.
When driving in challenging conditions, the vehicle dynamic control feature aids in maintaining adequate traction. However, the VDC limits engine output when the car is stuck in mud or snow, so you might need to switch it off to free your car. A VDC Off switch may be found in the majority of Nissan and Infiniti automobiles.

What does the dash-mounted Vehicle Dynamic Control Off indicator light mean?
The stability control system is not activated if the Vehicle Dynamic Control (VDC) OFF indicator light is illuminated on the dashboard. Nissan uses the name “Vehicle Dynamic Control,” which performs the same duties as a traction control system.
In inclement weather like snow, ice, or rain, the driver is more likely to lose control of the car without the VDC system. When driving in bad weather, the VDC system helps the driver by slowing down the engine and/or applying brakes to individual wheels that are sliding. This gives the other wheels the power they require so that the driver can keep the car under control. Although the VDC system is designed to help drivers maintain vehicle control, caution must still be exercised when braking abruptly at a high rate of speed.
Unless the car is trapped in snow or mud, it is advised to keep the VDC system on at all times. If the car does get stuck, it might be required to disable the VDC system in order to free it. When the car is turned on, the VDC system activates automatically. Turning the car off and back on should turn the VDC system back on if it has been switched off and the Vehicle Dynamic Control OFF indicator light is on in the display. It might also be possible to restart the system by pressing the VDC button once more.

How Does VDC Work?
On Nissan and Infiniti automobiles, the electronic stability control system is referred to as VDC, or vehicle dynamics control.
Since the 2012 model year, all vehicles and light trucks sold in the United States must have electronic stability control, a safety technology that is intended to avoid skids.
Prior to the 2012 requirement, all U.S.-market Nissan and Infiniti cars were equipped with VDC. Nissan first launched VDC in the U.S. in 2003 on the Infiniti Q45, Nissan Murano, and Nissan Pathfinder.
Similar to other stability control systems, VDC monitors the throttle and steering wheel positions, lateral acceleration, and other variables to determine when a vehicle is going to skid. It also employs sensors at each wheel to detect when any wheel begins to slip (lose traction). Then, to retain steering control, VDC steps in by decreasing engine power and quickly applying and releasing the brakes at individual wheels.
Every time the car is started, the system kicks on and doesn’t need the driver to do anything.
The basic operation of VDC is the same across all cars, but according to Nissan, the system is tailored to the performance needs of particular models and features, such as pickup trucks and SUVs with trailer-sway control and models with adaptive cruise control.
Why Is My Nissan Vehicle’s VDC Off?
It can be frustrating whenever the VDC light on your car starts to illuminate. You could be unsure of what this indicator light could signify and wondering if you need to make a costly repair. What does VDC Off on your Nissan imply exactly?
When the VDC stability control system is disabled, the Vehicle Dynamic Control, also known as VDC, activates. In the event that something goes wrong, this traction control system—which is exclusive to Nissan—works to maintain the stability of your car. Usually, it is an indication that the road conditions are bad.
We’ll go into more detail about the potential causes of your VDC system staying activated in the next sections. We will also tell you how to locate the VDC off switch and what you should do to maintain your car.
Safety Nissan’s Vehicle Dynamic Control (VDC) was described on Saturday.
At Nissan of LaGrange, every Nissan vehicle has Nissan’s Vehicle Dynamic Control (VDC). Traction control is improved upon by VDC over Traction Control System. In some handling circumstances, it aids the driver in maintaining control of the vehicle.
ABS, the traction control system, and the 2- or 4-wheel active brake limited slip all function in conjunction with VDC (if applicable). VDC adjusts the amount of engine power and/or applies brake pressure to specific wheels as necessary based on data from various sensors.
The operating characteristics of the vehicle are determined by seven sensors at any given time.
- Each wheel’s speed is monitored separately by four wheel speed sensors, which compare wheel speed to the vehicle’s real speed.
- The amount of brake pressure being applied to the wheels is monitored by the brake pressure sensor.
- The steering angle sensor keeps track of the steering wheel’s angle to assist in determining the driver’s intended course.
- The middle of the car houses a yaw rate/lateral g-sensor that keeps track of how the car is positioned in relation to the road. The amount that the vehicle spins around its vertical center axis is referred to as yaw. Forces applied to the vehicle from the side are referred to as lateral g’s. The sensors assist in determining whether the vehicle is slipping through a curve or otherwise moving away from its intended course.
The VDC control unit receives data on the vehicle’s behavior at any given time from all seven sensors. Based on this data, the VDC control unit sends a signal to the ABS, traction control, throttle, or individual brakes to be activated as needed to help keep the vehicle on its steering-directed course.
The back of a car will typically slide outward if it oversteers while negotiating a curve. When VDC is turned on, the system detects the onset of a slide and responds by applying brakes to the outside wheels and decreasing engine power to provide force in the direction opposite to the spin. This aids in keeping the car in its direction of travel.
Similar curves cause a vehicle to understeer, which causes the front wheels to lose traction and drift from the desired path of travel. In this case, VDC reduces engine power while applying brake pressure to the inside wheels. The driver is able to keep the directed course of travel while the front wheels regain control.
In all circumstances, full power returns as soon as VDC has assisted in bringing the vehicle under control.
VDC has the following advantages:
- By regulating the brake pressure on one or more wheels and the engine power output, it helps correct oversteer and understeer.
- It helps give better control on slick road surfaces and improves performance in emergency avoidance movements.
- It functions instantly and flawlessly in milliseconds.

What does the warning light for the vehicle dynamics control mean?
On the instrument panel is the Vehicle Dynamic Control (VDC) Warning Light. The VDC system will shut down if this indicator illuminates, indicating a problem with the system. In bad weather, you can still drive your automobile, but you should drive very cautiously. When you notice this alert, drive carefully because the traction is getting close to its limit. If the VDC Warning Light is blinking, the traction control system is now in use.
When the car is turned on for the first time, the VDC Warning Light briefly illuminates. If the light is left on, it becomes a problem.
What does VDC on a 2011 Nissan Sentra stand for?
Dear Ashlea: On the instrument panel is the Vehicle Dynamic Control (VDC) Warning Light. The VDC system will shut down if this indicator illuminates, indicating a problem with the system. In bad weather, you can still drive your automobile, but you should drive very cautiously. When you notice this alert, drive carefully because the traction is getting close to its limit. If the VDC Warning Light is blinking, the traction control system is now in use. The jerking acceleration would be brought on by the mass air flow sensor failing, which is unrelated to the VDC warning light. Therefore, I would advise replacing the mass air flow sensor or having a qualified mechanic visit your location to first perform a car jerking examination to confirm the precise cause of this symptom and offer the appropriate fixes.
