These wheel speed sensors work with the ESP BAS light to ensure that the wheels are spinning at the right and equal speed.  When you drive your vehicle on rocky or icy roads, the vehicle may lose traction. This loss of traction would cause to the sensors to have unusual readings causing the ESP BAS light on your dashboard to come on.

Bad Brake Switch:

When you hit the brake pad with your foot, the brake switch on the rear brake lights. This rear brake light is important for notifying the people at your back that you want to slow down or stop the car. Having known the importance of this switch, the ESP BAS light on your dashboard would notify you of the need to change the brake switch.

Wiring Issues:

Generally, there are a lot of wires in your car.  The wires connected to the ABS control sensors could sometimes wear out and get damaged and this triggers the ESP BAS Light. This happens because the wirings to the ABS control sensors are connected to the tyres which have the wheel speed sensors installed in them.

Bad Steering Angle Sensor:

In modern cars, steering wheel sensors are installed in the steering wheel. The work of the steering wheel sensor is to align the movement of the steering wheel with the tyres. A bad steering angle sensor would cause the ESP BAS light to blink on the dashboard.

  • Lastly, a bad rotor, pad or caliper would cause the ESP BAS light to come on.

These are the causes of the ESP BAS light. However, you can confirm the cause of the ESP BAS light by using the hand-held code scanning device attached to the ESP BAS system, if your car has one.

  • Sit behind your vehicle’s wheel and turn the steering to the right.
  • Turn the steering again to the left.
  • Bring the steering wheel to the right again until all the wheels are centered.
