Reasons for Illumination of an ABS Warning Light in a Saab From Experts in Decatur
The Anti-lock Braking System (ABS) warning on your Saab’s dashboard is an indication of a possible ABS malfunction. The ABS prevents your wheels from locking up during emergencies by restoring traction to the tires, allowing you to steer your vehicle safely.
The system is created with a speed sensor, a pump, valves, brake fluid, and a controller. Whenever there is an issue with the ABS, the warning light will activate and stay on to notify the driver that your emergency braking system is compromised. Discussed below are the reasons why the ABS warning light is beaming on your dashboard.
Reasons Behind Illumination of ABS Warning Light in Your Saab
Once there is an issue with any of the components that make up the ABS, it triggers the anti-lock braking system warning.
Low brake fluid
Brake fluid is vital for managing braking pressure in an anti-lock braking system. The ABS fluid is stored in a reservoir. Over time, leakage can occur due to punctured lines or a broken reservoir, resulting in a low fluid level. When the fluid level is low, it triggers the ABS warning signal on the dashboard, notifying the driver of an issue with the Anti-lock braking system.
Malfunctioning ABS module
The anti-lock braking system can break down after an extended period of use due to corrosion. When this happens, it hinders the system’s proper functionality, resulting in the illumination of the ABS warning on the dashboard.
However, routine inspections and maintenance will help detect corrosions in the ABS before it hinders the system’s proper functionality.
Faulty speed sensor
Every wheel’s hub of your Saab is equipped with speed sensors that calculate the wheel’s movement. The anti-lock braking system is then notified of this information. If the anti-lock braking system detects that at least one of the wheels is moving too slow, it increases the brake fluid pressure to allow the wheel to level up.
Whenever the speed sensor malfunctions, the anti-lock braking system notifies the driver by beaming the ABS warning on the dashboard.
Bad hydraulic pump or unresponsive valve
A hydraulic pump controls the braking fluid pressure in an ABS. The pump regulates the brakes by pumping brake fluid through a cylinder. The ABS can then lower braking pressure on individual wheels based on the speed data received from the speed sensor by the ABS module.
If the hydraulic pump or a hydraulic valve is broken, the situation could rapidly deteriorate, triggering the ABS warning signaling that the pump should be replaced. Dirt or metal shavings in the brake fluid can also cause the pump to wear out over time. However, this can easily be prevented by having your brake fluid checked by a professional any time you get your brakes done.
Symptoms of a Faulty Anti-Lock Braking System (ABS)
The most obvious sign of an issue with the anti-lock braking system is the activation of the ABS warning on the dashboard. When you start your vehicle, a check is conducted on all the systems prompting several lights to stay on for a few seconds then turn off. If the ABS warning light remains on after the system inspection, it indicates a problem with the system.
Another sign of a problem is if your brakes are unresponsive and sometimes behave erratically. You may have to punch your brake more than once before getting a response. The brakes may also make a random clicking sound or lock up unexpectedly. You should contact a professional immediately when you notice any of these signs to avoid putting yourself and other road users at risk.
