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.

What does the Nissan VDC light mean?
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.
What does your car’s VDC do?
Vehicle Dynamic Control, or VDC, monitors driver inputs and vehicle movements using a variety of sensors. It regulates brake pressure and engine output in specific driving situations to aid the driver in maintaining control.
Describe a VDC fuse.
VAC/VDC TYPES OF VOLTAGE This indicates that the fuse may be used in a circuit that operates at its maximum voltage. For instance, a fuse rated at 250VAC could be used in a circuit operating at 250VAC or one working at a voltage of less than 250VAC, such as 12VAC. However, the fuse must not be used in a circuit operating at a voltage of more than 250VAC, i.e.
Is traction control the same thing as VDC?
For front tire spin when the engine is on, use traction control. Before you realize it, VDC is increasingly active in correcting over- or understeer.
How can the VDC light on a Nissan Xterra be reset?
- Set the steering wheel in the forward position and start the engine.
- Drive the car for at least 10 minutes at a speed greater than 10 mph.
- The VDC OFF indication ought to illuminate.
How do you shut off VDC?
By providing braking pressure to specific wheels to maintain your INFINITI on your intended course, VDC can, if necessary, modulate brake pressure and engine power to help correct oversteer and understeer. By just pressing the VDC button, it is simple to turn VDC on and off. When Vehicle Dynamic Control is disabled, the VDC indicator will turn on. When you press the switch a second time, it will turn back on. When you start your car, the VDC should switch on automatically. INFINITI Vehicle Dynamic Control should generally be left on when driving, with the exception of when you’re trying to pull the car out of mud or snow.
What does Infiniti VDC off and slip mean?
Car can spin when VDC is turned off. Every time the ignition is switched off, this automatically turns on. When the ignition is turned on, it shouldn’t display “on” on the dashboard, and the VDC light shouldn’t be on. In other words, when the ignition is turned on, VDC is “off” rather than “on” for some reason.
My VDC light turned on—why?
Your vehicle appears to be experiencing a jerking reaction, which is typical when a cam position sensor starts to fail and causes the traction control system to activate. This suggests that you may have a defective cam position sensor. The engine control computer receives data from the camshaft position sensor, which detects the camshaft’s rotational position. Your car’s computer uses a camshaft position (CMP) sensor to track the camshaft’s rotational position in relation to the crankshaft position to determine which cylinder is in its power stroke. It modifies the fuel injectors’ operation and the timing of the spark plugs using this information. Thus, the CMP sensor has an impact on engine efficiency, emissions regulation, and fuel economy. The magnetic and Hall-effect types of camshaft sensors are the two most prevalent ones you all notice. Both send a voltage signal to the car’s computer or an electronic control module. The magnetic kind, which is distinguishable by its two wires, generates its own AC (alternate current) signal (a sine wave). The Hall-effect type includes three wires and is powered by an external source to generate a digital signal (a “square wave,” on-or-off). Your engine might include one or more cam sensors, depending on the precise model of your car. When the camshaft sensor malfunctions, the vehicle may jerk while losing power or have trouble accelerating past 35 to 40 mph. Additionally, the engine may operate poorly, have a hard time starting, surge, or fail to ignite properly.
The traction control system keeps an eye on the car’s steering and stability and activates when it notices a loss of traction. Electronic sensors are used at each of the four wheels to accomplish this, and they convey steering performance and stability in inclement weather conditions to the Powertrain Control Module (PCM). The traction control system prevents the car from sliding by slowing the engine and selecting which wheel to apply braking pressure to. Together, the traction control system and the anti-lock braking system keep the car stable. The computer makes decisions about how to operate the traction control system or the anti-lock braking system to best control the vehicle when necessary using the data it receives from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle. When the warning indicator light on the dashboard illuminates, there may be a number of problems present, including faulty steering angle sensors, faulty rotational speed sensors, and faulty wheel speed sensors as well as a steering rack issue. The traction control system may occasionally just need to be reprogrammed. Additionally, certain vehicles may enter limp mode, which prevents acceleration above around 30 mph, when any of these symptoms are found. I suggest having a specialist from YourMechanic visit your location to examine and diagnose your vehicle.
