How Does My Vehicle's ABS System Work?
Whether you drive a Honda, Subaru, Chevrolet, or Nissan, ensuring that your car’s an anti-lock braking system is in tip-top shape is essential. Your car's anti-lock braking system (ABS) is a safety system that prevents your vehicle's wheels from locking up when you brake. With your anti-lock braking system, you can maintain some steering ability and avoid skidding while braking. The anti-lock braking system modifies the brake fluid pressure to bring the speed of the wheel back to the minimum slip level that is mandatory for optimal braking performance. The system has four major components:
- Valves: There are valves within the ABS control unit that are controlled by the anti-lock braking system. In the first position, the brake valve is open, allowing the pressure from the master cylinder to be transferred to the brakes. In the second position, the brake valve remains closed and pressure from the master cylinder to the brakes is constrained. In the third position, the valve releases some of the pressure on the brakes. The third position is used as your car comes to a halt.
- Electric Control Unit: The computerized ECU receives signals from the sensors in the circuit and controls the brake pressure.
- Hydraulic Control Unit: By increasing hydraulic pressure, the computerized hydraulic control unit applies or releases the brakes under the anti-lock conditions, depending on the signals given from the ECU.
- Speed Sensors: These sensors, also known as “wheel speed sensors” or “wheel sensors,” monitor the speed of each wheel and determine how the wheels should accelerate or decelerate when you brake. If your vehicle needs a speed sensor replacement, come to Downtown Automotive in Nelson.
The anti-lock braking system monitors the speed of each wheel and keeps them turning at the same speed by applying the appropriate amount of pressure to individual wheels. Having a functioning anti-lock braking system helps you maintain control and decreases the chance of your vehicle skidding.
How Do I Know If My Vehicle Needs an ABS Wheel Sensor Replacement?
If there is an issue with your vehicle's anti-lock braking system, it is unlikely that we will have to replace the ABS entirely. Rather, one of the components of the ABS probably needs to be repaired or replaced. Here are some signs that your vehicle needs an ABS wheel sensor replacement:
- Your vehicle's ABS light turns and stays on: This dashboard warning light may flash momentarily when you turn your vehicle on, but if it stays on, it is a sure sign that something is wrong with your vehicle's anti-lock braking system. If your car does not have an ABS light, your Check Engine light will turn on.
- The stability and/or traction control systems are disabled: These systems rely on data from the anti-lock braking system to run, so if your ABS wheel sensor has failed, these systems may stop working. The stability and/or traction control systems are responsible for hill-start assist, stability control, and more, so it is imperative that they work. If you suspect something is wrong with these systems, give Downtown Automotive a call at 250-505-2110.
- It takes longer for your vehicle to come to a full stop: Because your ABS wheel sensor works with the rest of the anti-lock braking system to bring your vehicle to a quick and complete stop, the system will not work properly if one of its parts has failed. This could mean that it takes a longer distance for your vehicle to stop completely, which is certainly not safe and must be fixed as soon as possible.
- Your vehicle does not feel stable while braking: If your ABS wheel sensor is not working, it will not designate the right amount of brake pressure for your vehicle to brake correctly, which can be dangerous if not attended to immediately. We at Downtown Automotive in Nelson can help.
