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.

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.
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.

Meaning of VDC Light
The VDC light, which stands for Vehicle Dynamic Control, turns on when there is a problem with the traction control or anti-lock brake systems.
To increase traction, Vehicle Dynamic Control (VDC) collaborates with your car’s anti-lock brake system. You can notice some vibration in the brake pedal when VDC is engaged. This just shows that everything is operating as it should and does not imply that there is a problem with the system.
Most of the time, the VDC will apply brakes to each wheel individually to prevent any slippage. When the car is understeering, VDC brakes the outer front wheel, making it turn in the right direction. Although VDC cannot steer the car, it can provide feedback to help the driver control the vehicle.
The vehicle’s steering and direction are continuously monitored by the VDC system. It establishes the difference between what the driver intends and what the car really does. If the pathways are identical, VDC has no effect. In the event of a failure, the VDC system is able to prevent wheel slippage and traction loss.
VDC Nissan Navara: What is it?
Despite its modest commercial beginnings, the modern 4×4 dual-cab ute has grown to be a preferred option for many busy families and adventurous couples due to its great versatility and utility.
Enter the Nissan Navara STX 550, a vehicle loaded with modern conveniences including satellite navigation, a reversing camera with predictive route, dual-dial climate control, and an ear-pleasing Bose audio system. The off-road enthusiast who loves his or her vehicle shaken rather than stirred may go straight to the aftermarket suppliers.
But as soon as you leave the yard, shift the seven-speed auto’s lever to sports mode, poke the huge STX to exercise its muscles, and the 550 will put on a respectable rate of speed, quickly and easily pulling you away from your starting location.
The Nissan technical team quickly introduced its Vehicle Dynamic Control to provide both vehicle stability and occupant safety with unprecedented levels of performance (VDC).
What does this do then? In order to assist the driver in maintaining directional control and vehicle stability in a sudden swerve or low-traction situation, VDC monitors the vehicle speed and the driver’s handling of the steering wheel in addition to the vehicle’s anti-lock brakes and Nissan’s Active Brake Limited Slip system.
For inexperienced or distracted drivers, the likely result of unexpectedly encountering abnormal circumstances, such as slippery surfaces or the need to quickly change directions to avoid an obstacle in the vehicle’s path, can be the vehicle entering an uncontrolled slide, potentially with loss of steering control.
The most crucial task of the VDC, which a driver cannot possibly perform, is to apply braking pressure to specific wheels if it notices a sudden vehicle reaction outside of normal operation, such as a rapid and excessive directional change.
In order to prevent uncomfortable throttle pressure and to help the driver maintain steering control and desired direction, it also lowers engine power.
The VDC “Slip” indicator blinks to let your passenger know the system is working if you suddenly experience wheel spin.
Even though they were trying to accelerate quickly, the driver would already be noticing the diminished engine response. The system’s main goal is to increase the vehicle’s stability and handling dynamics while delivering secure and predictable control during a swerve-and-recover maneuver.
Off-road, however, there are situations in which lowering engine power to combat tire spin would be difficult, such as when navigating soft sand or pulling the car out of mud.
Fortunately, the ability of electronics allows the system to be turned off, allowing drivers to utilize the massive torque reserves of the engine when necessary. Both ABS and the Active Brake Limited Slip systems continue to support traction control for off-road driving even when the VDC is off by allocating drive to the wheel with the most traction.
It was a delight to drive the Navara STX 550, and with an ANCAP four-star rating and the addition of Nissan’s VDC, it provides even better levels of family safety and comfort.
