What should I do if the “TRAC OFF” indicator is turned on?

A traction control system-equipped vehicle’s dashboard will indicate the TRAC OFF light. By regulating the amount of power sent to the wheels, the traction control system, a safety feature, assists your car in maintaining traction and stability on slick surfaces. The traction control system is disabled or not functional when the TRAC OFF light on your dashboard illuminates. 

The system may have been manually disabled by the driver using a button on the dashboard if it is off. If the light suddenly illuminates, there may be a systemic issue, such as a broken sensor, defective wiring, or an issue with the ABS (anti-lock brake) system. It’s crucial to remember that while the TRAC OFF light is on, your car may have less stability and grip, especially in slick weather like rain or snow. Investigating and fixing the problem immediately is crucial because doing so increases the risk of slipping or losing control of your vehicle.

Common Causes

There are several reasons why the TRAC OFF light might illuminate a car’s dashboard. Here are some of the most regular reasons for this issue, 

Incorrect wheel speed sensors

The TRAC system uses sensors on each wheel to gauge each wheel’s speed and adjust the braking pressure accordingly. It can fail due to a broken sensor, resulting in the TRAC OFF light turning on. The TRAC system receives information about braking applications from the brake switch. The TRAC OFF light may be illuminated if a defective switch causes the TRAC system to shut off.Incorrect wheel speed sensors

Faulty brake pads

The TRAC OFF light may come on due to uneven braking brought on by worn brake pads, which can also cause traction to be lost. Low brake fluid levels can impair the functionality of the TRAC system and cause the TRAC OFF indicator to illuminate. A bad ABS module is one of the main reasons why the TRAC OFF light appears to be emitted. Controlling the hydraulic pressure within the brake system is the responsibility of the anti-lock braking system (ABS) module. When the TRAC system malfunctions, it can illuminate the TRAC OFF light due to a defective module.Faulty brake pads

Troubles with the electricity

The TRAC system may malfunction and turn on the TRAC OFF light due to electrical problems such as loose connections or broken wiring. The Electronic Control Unit (ECU) of the vehicle regulates a number of systems, including the TRAC system. The TRAC system can fail and turn on the TRAC OFF light due to a malfunctioning ECU.

The TRAC system may also malfunction due to other problems, like a broken steering angle sensor or throttle position sensor. It is always recommended to have a skilled mechanic diagnose the problem to guarantee a quality fix.

Failed wheel bearing

The ability of the wheels to rotate smoothly is due to the wheel bearings. The TRAC system may malfunction, and the TRAC OFF light may turn on due to the wheel wobbling due to a damaged bearing. The ABS sensors are in charge of determining the speed of each wheel. The TRAC system could malfunction, and the TRAC OFF light might illuminate if they are soiled or polluted.Failed wheel bearing

Sensor for steering angle failure

The steering angle sensor monitors the angle of the wheel and aids the TRAC system in determining the direction of the vehicle. The TRAC system may break down if the sensor fails, and the TRAC OFF light may come on. The yaw rate sensor measures the vehicle’s rotation about its vertical axis. The TRAC system could malfunction if the sensor fails, turning on the TRAC OFF light.Sensor for steering angle failure

Broken vacuum actuator

The vacuum actuator regulates the TRAC system’s brake pressure. Its failure may result in a malfunction of the TRAC system and the illumination of the TRAC OFF light. The pump provides the TRAC system’s hydraulic pressure. If it malfunctions, the TRAC system may experience issues, and the TRAC OFF light may turn on.Broken vacuum actuator

The unresponsive traction control module

The traction control module manages the operation of the TRAC system. If it malfunctions, the TRAC system may get damaged, turning on the TRAC OFF light. The steering rack is responsible for getting the driver’s input to the wheels and turning them. If it malfunctions, the TRAC system may get damaged, turning on the TRAC OFF light.

Ruined throttle body

The throttle body manages the engine’s air intake. If it malfunctions, the engine may lose power, leading to a TRAC system malfunction and the illumination of the TRAC OFF light. The mass airflow sensor counts the number of cubic feet of air entering the engine each second. If it malfunctions, the engine can lose power, which would cause the TRAC system to break down and turn on the TRAC OFF light.Ruined throttle body

Malfunctioning sensors for the crankshaft and camshaft

The engine’s crankshaft position is determined via the crankshaft position sensor. If it fails, the engine may stall or lose power, leading to a TRAC system malfunction and the illumination of the TRAC OFF light. The camshaft position sensor determines the engine’s camshaft position. If it fails, the engine can stall or lose power, resulting in a TRAC system malfunction and the TRAC OFF light turning on.

What are the bad impacts of TRAC OFF Light?

The traction control system in your car has been turned off, according to the TRAC OFF indicator. The performance and safety of your car may suffer if the traction control system is turned off. The following are some negative effects of TRAC OFF light:

  • Your car’s traction control system aids in keeping traction while braking or accelerating. Your car’s traction and stability will face a problem if the system is off, especially in slick weather like rain or snow.
  • When turning or braking on slick roads, your car is likely to skid or lose control if the traction control system isn’t engaged. Accident risk may rise, especially if you’re traveling quickly.
  • If this problem arises, increased Wear and Tear will be evident. The wheels might spin more freely when the traction control system is turned off, which might lead to additional damage to the tires, brakes, and other parts of the car.
  • Lower Fuel Efficiency. Without the traction control system, the wheels spin more freely, requiring more effort from the engine to keep the speed, which decreases fuel economy.
  • The TRAC OFF light could be an early indicator of further problems with the car, such as a broken ABS, which would result in less effective braking and a longer stopping distance.

TRAC OFF Light vs. Check Engine Light (CEL): Full Comparison

Warning lights on your car’s dashboard include TRAC OFF and Check engine. The TRAC OFF and Check Engine lights differ primarily in the following ways:

Difference-1

In contrast to the Check Engine light, which signals an issue with your car’s engine or emission control system, the TRAC OFF light shows that the traction control system in your automobile is turned off.

As the vehicle accelerates or brakes, the traction control system helps keep the wheels from slid­ing off the road. When the traction control system is shut down, as indicated by the TRAC OFF light turning on, you will no longer benefit from the system’s increased safety features. Contrarily, the Check Engine light can reveal various problems, such as engine misfiring, sensor malfunction, fuel system problems, etc.

Difference-2

The two lights’ indications of the concerns’ seriousness can vary. Although the TRAC OFF light may suggest a potential safety hazard, it often isn’t an urgent issue that must be fixed immediately. But, if a serious problem isn’t fixed immediately, the Check Engine light may signal engine damage.

Difference-3

The two lights’ fixes may also be different. The traction control system is frequently the cause of the TRAC OFF light, and addressing the problem can require replacing or repairing system components. The precise problem code or issue the diagnostic scan identifies may determine the correct course of action for the Check Engine light.

Difference-4

One of the preliminary core differences between these two is the triggering circumstances. When the driver disables the traction control system or when the system detects a defect that necessitates its deactivation, the TRAC OFF light is activated. But, when the car’s onboard computer system notices an engine or emission control system issue, the Check Engine light comes on.

Difference-5

An amber-colored indicator known as the TRAC OFF light typically shows on the dashboard to show that the traction control system is off. An issue with the engine or emission control system is indicated by the Check Engine light, which is typically a dashboard icon in yellow or orange. The vehicle’s onboard computer system must be scanned for fault codes connected to the traction control system using specialized diagnostic equipment to identify the problem causing the TRAC OFF sign to illuminate. An OBD-II scanner is used to read the error code and pinpoint the fault, which is the cause of the Check Engine light.

Difference-6

In terms of the Visibility option, they are very different. And as soon as the automobile starts moving, this becomes clear. The TRAC OFF light does not display on all vehicles and is less frequent than the Check Engine light. On the other hand, all contemporary automobiles come equipped with the Check Engine light, which is a common warning indicator.

Difference-7

When the TRAC OFF indicator is illuminated, the traction control system is disabled, which may result in less traction and stability in slick conditions. Reduced performance, decreased fuel efficiency, or other engine or emission control system issues may occur when the Check Engine light is illuminated in a vehicle. The TRAC OFF light denotes that the traction control system is off, but the Check Engine light denotes an issue with the vehicle’s engine or emission control system. While both lights need to be fixed, the severity of the problems and their solutions can vary. If you wish to avoid further harm to your car, taking both lights seriously and repairing the issues is crucial.
