What Does It Mean When Mercedes-Benz ABS Light Comes On in Wilmington?

In general, the ABS or anti-lock braking system is responsible for sticking the tires to the road when you are braking the Mercedes-Benz. When the ABS has any issues, the tires are losing contact with the road and end up skidding.

Moreover, the main function of the ABS is to prevent the car's wheels from locking up. Thus, the anti-lock brakes are controlling the brakes for improving the driving ability of the MercedesBenz. When you start the engine, the ABS light is flashing on the dashboard. Thus, the activated ABS warning light comes on and off is normal and lasts for about 2 to 4 seconds.

But, when the ABS light stays on for longer, then it would have a problem. So, you need to consult with a mechanic for diagnosing the main reason behind the activated ABS light in the Mercedes-Benz. The following points define the reason behind the ABS light come on.

Failed speed sensor The main task of the wheel speed sensor in the Mercedes-Benz is to record the speed of the car’s wheels and give complete details about the speed to the engine control unit. However, the ECU is controlling the multiple systems in the car such as the ABS. When the ECU of the car is detecting that one of its wheels is moving slower than the other, then the ECU is releasing the brake fluid for allowing the wheels to move at the same speed as other wheels to maintain the grip of the road.

All we know that the speed sensor is located close to the wheels and damaged due to the high heat of the brakes. Due to any reason, if the speed sensor is not working efficiently, then the ECU unable to get the required data and illuminate the ABS light.

Lower level brake fluid To run the brake efficiently, the ABS module is relying on the hydraulic brake fluid that is driven through the cylinder. When the brake fluid level is lower down in the brake reservoir, then it will put some bad effects on the functions of the ABS. Due to the lower level of the brake fluid, the ABS light is illuminated on the dashboard. On the other hand, the low brake fluid is also caused due to the leaky seal, the air in the system, and leaky fluid reservoir.

Moreover, the ABS light also comes on when the brakes are worn out and need a reputed mechanic for fixing it as soon as possible. Without the proper amount of fluid in the system, the

ABS module unable to balance the brake pressure on each of the wheels and cause skidding as well as other issues.

Damaged hydraulic pump Through a hydraulic pump, the ABS is controlling the brake fluid pressure. Thus, the pump is applying the brake fluid through a cylinder for controlling the brakes during the normal braking of the Mercedes-Benz.

On the other hand, the ABS is lowering down the brake pressure of each wheel based on its speed reading by the speed sensor. If the hydraulic pump or valve is damaged or not working properly, then the whole system can be blown out and activate the ABS light.

Over time, the hydraulic pump can be worn out and contaminate the brake fluid due to the dirt or metal shaving in the fluid. Check the brake fluid as soon as possible for preventing the issues of the braking system whenever you apply the brakes.

Failed ABS module Apart from the other issues, the failed ABS module also activates the ABS warning light on the dashboard. Moreover, the ABS module is typically associated with the wiring in the MercedesBenz. On the other hand, due to the corrosion, the ABS module wiring is also going bad.

Neglecting the issues can delay the communication between the wheel speed sensor and the ABS module. In these circumstances, the Mercedes-Benz will need a bit of rewiring and need the complete replacement of the ABS module for preventing the issues.

Conclusion Like other problems in the Mercedes-Benz, the fuse box of the ABS also goes bad and triggers the ABS light on the dashboard. If you are living in Wilmington, then consult with a certified mechanic for fixing the ABS warning light on the dashboard of the Mercedes-Benz.
