Top 5 Bad or Failing ABS Control Module Symptoms

The anti-lock braking system quite popularly known as the ABS control module prevents your vehicle’s wheels from locking while you are driving. The ABS control module is the most needed when you suddenly apply the brakes to avoid some accident or emergency. It will sustain the traction in your vehicle’s wheels, once you have applied the brakes.

Amidst the importance of the ABS control module, have you ever encountered ABS failure? As an effective ABS control module is so important and needful for a secure driving, the ABS control module symptoms should never be ignored. Driving with the bad abs module can bring many disadvantages to the car’s performance and will also degrade the efficiency of the engine.

Where Is The ABS Control Module Located?

The ABS control module acts as the “brain” of the whole anti-lock braking system. It processes information from the ABS sensors and controls brake pressure through the ABS modulator. In most conventional automobile designs, the control module is installed and mounted in the engine compartment or located close to the master cylinder, which is the main component of your brake system.

If the ABS sensor detects that the vehicle is losing traction, it sends a signal to the ABS module to brake quickly. This produces intermittent braking and some steering control.
