Several things can activate the VSC and TRAC light. You need to understand these triggers if you want your car’s safety features to always work without a problem:
1. Bad wheel speed sensors
Broken or malfunctioning wheel speed sensors are one of the most common reasons for the VSC OFF and TRAC OFF lights to come on. These sensors are installed on each wheel of your vehicle.
They help the ABS assess how fast each wheel is turning. If even one of these sensors fails, the VSC OFF or TRAC OFF light will activate.
2. Dirty sensors
The wheel speed sensors in the VSC and TRAC systems are very sensitive. They do not need to be broken to activate the lights. Dirty sensors cannot function properly. If they are dirty, the VSC OFF or TRAC OFF light will appear on the instrument panel.
3. Faulty ABS control module
If your car’s ABS control module is malfunctioning, it could also cause the VSC OFF or TRAC OFF light to come on. This module is responsible for controlling the ABS of your car. Without it, your vehicle is not safe to drive.
4. Newly fitted tires
Fitting new tires on your vehicle can also activate the VSC OFF or TRAC OFF light on your dash. This usually happens if the new tires you are installing are incompatible with the tires recommended by the vehicle manufacturer.
They may not be the same size or tread pattern as the tires you replaced. This can confuse the computer that regulates the operation of your vehicle’s tires and turn on the VSC OFF or TRAC OFF warning light.
Again, why are the VSC and TRAC OFF lights on? The VSC and TRAC OFF lights may be on due to a problem. If they are not having trouble checking, you can press and release the VSC and TRAC OFF buttons to turn them off.
5. Flat tires
Even underinflated tires can cause the TRAC OFF and VSC OFF lights to come on on the dash. The warning light will come on even if only one of these tires is flat.
The reason is that tires with low inside pressure can cause the wheels to spin unevenly. This situation will ruin the ABS of your car.
6. Newly installed brakes
If you replaced the faulty brakes with new brakes, it could also cause the VSC and TRAC OFF lights to come on on your dashboard.
Again, if the new brakes are incompatible with the car manufacturer’s recommended brakes, they will damage your car’s ABS and cause the VSC and TRAC warning lights to come on.
7. Problems with the brake light switch
Problems with the brake light switch can also cause the TRAC OFF light to come on on the dash. You will find this brake light switch near the brake pedal.
Step on this pedal and your car’s brake light will come on. So if the switch fails you will see the TRAC OFF light on your dash.
8. Loose wire connections
If your ABS electrical wiring connections, it will also activate the VSC OFF and TRAC OFF lights on your instrument panel.
The reason is that the traction control system components, along with their sensors, have electrical wires connecting them. If only one of these wires is loose or disconnected, you will see the TRAC OFF light on your dash.
9. Traction control system off
If your vehicle’s traction control system has been turned off accidentally or on purpose, its warning light will flash on the dash. You will not be able to enjoy this security feature while it is disabled.
10. Faulty ECU
Your vehicle’s ECU, or electronic computer unit, is a complex device. It is sufficiently protected from any external element that could cause it to malfunction. However, it is still a human-made device subject to stress, wear and tear, and outside elements that will cause it to malfunction.
When it malfunctions, one result is that the VSC and TRAC OFF lights will come on on your dash.
In conclusion
If the VSC TRAC Off warning light appears on the instrument panel, either from a trigger or by accident, your vehicle’s vehicle stability control system and traction control are no longer working. The VSC is represented by a sliding carriage accompanied by the word OFF.
When you see these lights on the instrument panel, there could be a problem with your car’s VSC and TRAC systems.
You need to take your car to the car dealer to find out why it showed up on your dashboard. They should have a qualified mechanic who can diagnose and identify the cause and fix the problem.
