ABS sign on the car dashboard is on
On the dashboard of the car sometimes the ABS (ABS) sign lights up, about the main task of which not every driver knows. Almost all modern vehicles are now equipped with front and rear ABS, which seriously affect the drivability of the car. So why did the ABS sign light up, what is the cause and how to fix it?

ABS in a car
ABS in a car prevents the wheels from locking when braking the car. The whole meaning is disclosed even in the name – anti-locking system. That is, if any wheel gets blocked in motion, it will loosen its grip, and it will start spinning slightly as it moves. Even while holding the brake pedal, the driver will notice the wheels spinning and locking for a second, which affects the safe braking process and the complete stop of the car.
The anti-locking system will allow you to maintain control over the car during hard braking. In its absence, the wheels of the car will simply block during emergency braking, due to which the driver will lose control, despite attempts to turn the car and stop it.
Why has the ABS sign lit up?
The first sign of malfunction of the antilock braking system in the car is a lit sign of 3 letters on the dashboard. Like all important car electronics that are part of the electronic control system, the antilock system carries out its own diagnostics after each ignition switch on. If malfunctions are detected during this diagnosis, a light will be illuminated on the dashboard and will not go out. The illumination of the ABS sign for a couple of seconds after switching on the ignition should not embarrass the driver: it indicates that the self-diagnosis began.
Causes of ABS malfunction in the car:
Contaminated front or rear ABS sensors. For this reason, they will not be able to transmit accurate information, which will cause erroneous conclusions to be drawn about the performance of the sensors;
Broken wheel sensor;
Problems with the rim on the hub;
Loss of communication between the sensors and the unit, causing the information not to be transmitted correctly;
ABS problems should not be confused with problems with the vehicle’s braking system as a whole. Problems with the braking system on the dashboard of the car is indicated by a red exclamation mark.
What to do if the ABS sign lights up?
Initially, the driver should perform a diagnostic to pinpoint the presence of the problem, not just a malfunctioning car dashboard. Once the real problem is identified, there are two ways to try to fix it:
Disconnect the battery terminal for 20-30 minutes to reset the electronics and restore once the battery is connected. Sometimes this helps to fix the problems with the electronics themselves, and the dashboard will start displaying information correctly;
Get the ABS to work “manually”. It is enough to accelerate the car to 40 kilometers per hour on an empty and flat road and sharply press the brake pedal for full braking. If the lamp on the dashboard will not stop burning, then the problem requires the attention of the master of the car service;
Inspect the front and rear ABS sensors and units, check their integrity and consistency with their original appearance. Perhaps the sensor on one wheel is bent and damaged, which could cause the three-letter sign on the dashboard to light up. This will allow you to accurately understand for yourself the cause of the problem;
Check the condition of the wires and contacts. If while driving, the ABS sign lights up and turns off, then the problem is in the wires and contacts.
The most serious cause of the illuminated sign of three letters on the dashboard can be a breakdown of the ABS module and unit. Despite their durability, it is quite possible.
If after the ABS repair in the car service, the sign on the dashboard continues to light up, the problem may be the usual forgetfulness of the master. After ABS repair, you need to reconnect all the sensors.
Trying to disconnect the ABS sign on the dashboard yourself or perform a complicated repair is highly discouraged. Only a qualified car service technician will be able to perform ABS repair if the module or the sensor itself is broken. It is important to pay timely attention to the state of the system, as it fully affects the controllability of the vehicle and makes driving safer during emergency braking.
