Should the "VDC" light be on or off? 2012 Nissan Xterra

Hello, i have a nissan xterra model 2012.it's VDC is working properly. my question is that should the light be "on" on the dashboard or not while I am driving and the weather is clear? no rain no snow. what time the engine output due to VDC is reduced?
thanks,

My car has 25000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there – when the "VDC" light is illuminated on your dashboard, that means that Vehicle Dynamic Control is "OFF". It should be "ON" normally, so that it automatically steps in to reduce power when wheel spin is detected during snow or ice for example. You would intentionally turn VDC off when you were stuck in mud, or some other condition where wheelspin might normally result, but is OK. (You may not want your teenage son to be made aware of this!)

This light comes on when the vehicle`s dynamic control switch is off, or when the vehicle dynamic control system is not functioning properly. Follow this procedure To reset the Vehicle Dynamic Control (VDC):
The VDC and Slip Light illumination could be an indication that you are getting low on brake fluid, due to worn brake pads. Low brake fluid could cause the throttle control to kick in when a sudden vehicle movement is made, causing the vehicle to lose speed.
The VDC should turn on automatically when you start your car. In general, INFINITI Vehicle Dynamic Control should remain on while driving except when you are attempting to remove the car from mud or snow.
If the VDC Warning Light is blinking, then the VDC or traction control system is currently being used; when you notice this alert, be careful with your driving, as the traction is near its limit. Tips The VDC Warning Light will briefly illuminate when the vehicle is first turned on.
To do so, simply press the VDC Off switch. A warning light will illuminate on the instrument panel to confirm that the system is turned off. After you have unstuck your vehicle, press the switch again to turn the system back on.
Both Nissan and Infiniti vehicles have a Vehicle Dynamic Control (VDC) system, and it functions in the same manner as most electronic stability control systems. It uses various sensors to monitor driver inputs and vehicle motion, gently aiding the vehicle`s ability to stay on the driver`s intended path.
VOLTAGE TYPES (VAC / VDC)

This means the fuse can be used in a circuit he voltage maximum operating at this voltage . For example; if your fuse was rated at 250VAC, it could be used in a 250VAC circuit or in a or less lower voltage circuit such as 12VAC, but it must not be used in a circuit operating above 250VAC ie.

VDC then intervenes by reducing engine power and rapidly applying and releasing the brakes at individual wheels to maintain steering control. The system becomes active each time the vehicle is started, and it requires no action from the driver to engage.
VDC (Volts Direct Current) is the voltage of a direct current (DC) circuit. Direct current is a type of electrical current that flows in one direction only. Unlike alternating current (AC), which changes direction periodically, DC current flows in a constant direction.
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 in adverse weather conditions by reducing engine speed and/or applying brakes to individual wheels that are slipping.

ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

ANSWER : Hi there. The best way to determine what is causing these lights to illuminate on your dashboard is to have a professional mobile mechanic come to your location and complete a check engine light inspection. When your lights illuminate, it is due to a fault code that is stored in the ECU, related to the light that is being triggered. For example, if the brake light is on, it’s a mechanical or electrical fault within one or perhaps several of the components that comprise the entire system. With so many lights on the dash, it is possible that this is just a minor electrical glitch that can be resolved by clearing the codes during the check engine light inspection.

First, the fuse 19 keeps blowing. When I hit the brake pedal my dash lights up. The third brake light acts like a running light.
ANSWER : Hi there. Check the wiring on the vehicle to the tail and brake lights. There is a cross short that is causing the lights to blow the fuses and make the tail lights brighter than normal. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.

ABS light on, ESP light on,Traction OFF light on, engine light on, rides perfectly OBDI reads only Front Right Wheel Speed Sensor
ANSWER : If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

signals, daytime running lights are not working, park brake light on dash is on steady and chime is dinging steady 4×4 wont engage
ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.
