The more technology advances, the more features are added to our cars, so it wouldn’t be weird if your car has a button that dials VDC-Off or one light on the dash it does, and you don’t know what the abbreviation stands for. But you can rest easy, since here we will explain everything you need to know about the subject, so stay until the end.

What is the VDC system?

First of all, the VDC in a car it’s the same as electronic stability control (ESC), which has been required on vehicles sold in the United States since 2012. VDC it means Vehicle Dynamic Control (Vehicle Dynamic Control) and is basically a technology that seeks to combat the loss of steering control that can occur in slippery conditions. Some car manufacturers who refer to the ESC as VDC include infinity, nissan Y subaru.

Electronic stability control systems use computer technology to detect wheel slip before it is apparent to the driver. Later, to prevent a more significant loss of traction, they apply countermeasures that the driver cannot.

For example, him VDC system you could apply the brakes to individual wheels to counteract slippage. If a vehicle starts out unresponsive to the steering wheel’s cue to turn and instead pushes forward in a straight line, VDC will apply the brakes to the outside front wheel, forcing the car to turn. The VDC does not steer the vehicle. Instead, it provides inputs that allow the driver to continue steering the car in the direction they want it to go.

During normal driving, a VDC system It continuously monitors the direction and direction of the vehicle. Thus, it compares the expected direction of the driver determined by the angle of the steering wheel with the actual direction of travel of the vehicle. Usually, the predicted route and the actual route of travel are the same, but if there is wheel slip and loss of traction, they may differ. The system determines the difference between the intended and actual steering and issues electronic commands to the car’s systems to mitigate the problem.

If the light indicating VDC-Off is illuminated on the dash, this is an indication that the stability control system is not activated. Without the VDC system, the driver is more likely to lose control of the vehicle in adverse weather conditions, such as snow, ice, or rain.

The VDC system assists the driver by slowing the engine and/or applying the brakes to individual slipping wheels in inclement weather. This provides the necessary power to the other wheels that is necessary for the driver to maintain control of the vehicle. Although the purpose of the VDC system is to help drivers maintain vehicle control, it is still necessary for drivers to exercise caution when stopping suddenly at high speeds.

Manufacturers that use the VDC system in their vehicles

Subaru VDC System

As for the Subaru VDC (Vehicle Dynamics Control) system, it uses a network of sensors installed in the vehicle to control wheel speed, steering wheel position, yaw rate and lateral acceleration.

Most Subaru models have all wheel drive standard, so the system Subaru VDC use AWD to maximize traction and restore vehicle stability. This usually happens before the driver realizes there is a problem. If this fails to restore adequate traction and stability, the VDC it will take further corrective action by adjusting the torque applied to the front and rear wheels and applying the brakes to individual wheels.

Subaru VDC

subaru He states that with AWD, the braking wheel will regain traction more quickly than in a two-wheel drive vehicle, returning the car to its intended path. Beyond that, the system could alter engine timing and reduce fuel flow to the engine to limit torque, which would improve stability.

Nissan and Infiniti VDC system

Both the cars nissan like infinity have the system VDC and it works in the same way as most electronic stability control systems. Employing various sensors to monitor driver inputs and vehicle movement, helping to stay on the driver’s intended path.

The VDC of nissan and infinity helps control and limit both understeer and oversteer. If a vehicle is understeering and doesn’t respond as quickly as desired to a left or right turn input, just push forward. Conversely, if you are oversteering you are turning faster than desired, giving the driver the impression that the rear end is spinning, and if the oversteer is not corrected, the car will skid.

Nissan and Infiniti VDC

To counter these actions, the Nissan/Infiniti VDC system monitors brake pressure at individual wheels and regulates engine power to help the driver maintain control of the car in oversteer and understeer situations. To help maintain overall stability while driving, it uses brake pressure to reduce slip from a drive wheel that is losing traction by transferring power to a wheel that is not slipping on the same axle.

The vehicle dynamic control feature helps the car maintain proper traction when driving in adverse conditions. However, when the vehicle is stuck in snow or mud, the VDC It reduces engine power and you may need to turn it off to get your vehicle out. On most Infiniti and Nissan vehicles, there is a switch that marks VDC-Off or similar in order to turn it off.

When should I press the VDC-Off button?

The Once you should shut down your system VDC is if it is stuck in the mud. Since the limited power of the engine will prevent your car from going off the ground. so i should activate VDC-Off if you want the engine power needed to get you out of such situations as stuck in mud or snow. Therefore, it is recommended to leave the VDC system on at all times.

Please note that the VDC system turns on automatically when the vehicle is started. If you pressed VDC-Off when turning the vehicle off and on again, the VDC system should also be turned back on. Although it is also possible to press the VDC button again to turn the system back on.

How can I tell if my vehicle’s dynamic control system is malfunctioning?

If you don’t turn off the VDC-Off indicating light, this means that your car may not work properly. So you’ll want to locate a code reader (also known as an OBD reader) to determine where the error could be occurring.

If you have already tried to turn off the VDC system with the dash switch, your problem could be one of the following:

  • problems with your ABS brake system
  • Sensors on your steering wheel
  • Sensors on its wheels for speed

What if the VDC light is off and doesn’t come back on?

If your VDC light stays off and doesn’t come back on, that means you need to get your car serviced. Start by checking the fuses to make sure none of the dash lights have blown. After determining that your fuse system is working properly, take it to a mechanical workshop for your review.

How much does it cost to repair a VDC system?

The repair of a vehicle dynamic control it can cost up to $1,600. However, the switch is likely to break, which could only cost about $80 to repair.

To prevent someone from ripping you off, try to check if you can remove the switch from the VDC system. You will need to test the inside of the button with a multimeter, just like you would your starter, you will know that your VDC system it is working if it receives a minor electrical charge. Be sure to turn off the engine while performing this test.
