Slip light: what causes it to illuminate

Your car has a number of cutting-edge safety features that will provide you with a more stable ride, and one of them is the slip light. Every malfunction has a unique light on your car’s dashboard. The slip light is one that you might not be accustomed to seeing. It looks like an automobile on a slick, wavy road. Well, in this article we’ll be discussing about slip light.

So, let’s dive in!


What is a slip light?

When driving on a piece of a surface that is slick, the slip light control is intended to help you restore traction. When there is a problem with the traction control system, the slip light will illuminate the dashboard of your automobile.

Your vehicle’s wheels include sensors. The Powertrain Control Module (PCM) receives the data. The PCM will be able to determine whether a particular wheel is to blame for the car losing traction when the data is delivered. In order to restore stability and traction, it will automatically alter the power being delivered by the engine to the problematic wheel or wheels.

When traction is regained, the slip light may flash briefly before going off in typical driving conditions. However, there can be a serious issue if the slip light illuminates and remains on.

How slip light works

The slide control was developed to prevent drivers from losing control when driving in bad weather. The ABS and wheel sensors are crucial components of this system. The wheel sensors can assess traction loss and steering angle by exchanging data with the PCM.

When the slide control is engaged, the car will gradually lose power, and drivers will have much better control over the vehicle. The traction control system includes solenoids, electric pumps, high-pressure accumulators, and ABS and wheel sensors. These auto parts are essential for slip control to function properly. For instance, the accumulator aids in spreading the pressure put on the wheels. Additionally, the solenoid will act as a point of isolation between the brakes’ circuits.

What Causes the Slip Light to illuminate

Poor Wheel Sensors

Wheel sensors, also referred to as ABS sensors are responsible for returning data to the PCM. Every wheel has a separate sensor. The sensor notifies the PCM that there is a loss of traction when one wheel is moving at a rate that is different from the other wheels. When a wheel sensor is defective, it may send incorrect data, which will result in the traction control system failing. If this occurs, there is a strong probability that both the ABS warning light and the slip light will illuminate.

Driving on a slippery surface

The slip light is one that could turn on to signify typical operating circumstances. It differs from the majority of dashboard warning lights because of this. The slip light will flicker on the dashboard when you encounter a stretch of slick pavement and the wheels begin to spin. In most circumstances, the moment traction is regained, the slip signal will switch off instantly. One of the other mechanical issues is to blame if it persists.

Damaged ABS Rings

There is an ABS ring on each wheel. This ring will allow the wheel sensor to gauge the wheel’s speed. The rings are used by the sensors to gauge speed. The wheel sensor will get inaccurate speed information if the ABS ring breaks. The PCM receives this incorrect information, and as a result, the traction system may become unbalanced. The slip light and ABS light will likely be shown on the dashboard as well.

Faulty Wiring

The several wires that make up the ABS system must all be in perfect shape in order to transmit signals back and forth. You will notice the warning lights if a wire connecting the wheel sensors and the ABS control unit is broken or malfunctioning. Sometimes a wire could simply come loose and reattach quite quickly. On the other hand, locating the defective wire can be difficult and take some time.

Faulty ABS Control Unit

The ABS control, which is regarded as the operation’s brain, controls the entire process. This crucial component keeps an eye on the ABS sensors and responds by using the ABS modulator to modulate the braking pressure. The ABS light and the slip light will turn on when the ABS control unit is damaged. You may quickly fix the damage with the help of a diagnostic scanner by determining where it is.

How to repair a slip light

You must identify the source of the issue before you can turn off the slip light;

Read the trouble codes from the ABS control module

Onboard diagnostics are a standard feature in all contemporary cars and tell you what’s wrong with your car. You can read the system’s errors using an OBDII code reader that is compatible. Not all of them, but you must have one that specifically reads the ABS control module.

The diagnostic port is located under the steering wheel. Connect your code reader there. The majority of error codes are universal, which means that each manufacturer uses the same code to denote an issue. Some manufacturer-specific codes, meanwhile, could be more difficult to decipher.

Check the ABS rings and sensors for any fault

To find the location of the ABS rings, see the service manual. To see them, you occasionally need to enter the hub. As soon as you reach the ABS rings, check them for any indications of damage and repair them as necessary.

Finding any damage on the wheel sensors is significantly more difficult. If you clean them off, you might be able to get them to reconnect more easily. Occasionally, a build-up of filth and grit on the sensors can cause problems.

Call a Professional

It’s time to quit worrying and put your trust in the experts at this stage. Find a local ASE Certified Mechanic who can assist you in identifying and fixing the slip light. Ask those you know for counsel if you’re unsure of who to believe. You may also examine internet evaluations of nearby stores to find out which are well-regarded.

Pros and cons of having slip light


Prevents Car Accident

The fact that slide control lowers the risk of a car accident is one of its most important benefits. However, contrary to what many drivers believe, it cannot ensure a trip free of accidents. More specifically, they give drivers more control in challenging circumstances, which is quite handy. Because of this, even with slide control fitted, vehicle owners still need to exercise caution to prevent irresponsible driving.

Easily installed

Slip control is simpler to install than other auto parts.  Both ABS and slide control are currently standard in the majority of cars today.


High Cost

Cars equipped with a traction control system are often more expensive than others due to their convenience. Although the cost will eventually go down when technology is used more widely, the high cost of this system is still a major issue.

Maintenance process

Both the slip control technology and the slip light contain a variety of electronic components. There is no doubt that these components excel at their tasks. Over time, they will deteriorate and get filthy. Additionally, repairing these system components after damage or error is unquestionably very expensive. Not to add, the expense of repairing the dashboard’s primary computer is exorbitant.

Limited Control

Contrary to popular belief, many drivers prefer to have greater control over their cars than to rely solely on slip control. For instance, traction control will prevent skilled automobile owners, such as race drivers, from driving quickly and drifting as they choose.
