What does it mean when ABS and brake light come on?
If both the ABS and the brake system light come on at the same time, your vehicle is no longer safe to drive. This means there is a serious problem with the car’s braking system and continuing to drive puts yourself and others at risk.
Is it safe to drive with ABS and brake light on?
It is not safe to drive with an ABS and brake light on because you won’t have the safety feature that the ABS is providing. If you have to make an emergency braking, your braking distance will be longer than usual and your wheels will lock-up and you won’t have control over steering when braking.
What 2 reasons would cause your brake system warning light to come on?

Will a bad master cylinder cause ABS light to come on?

A typical ABS sensor will cost about $80 to $125 however, on some makes and models the sensor is part of a hub/bearing assembly (GM, Ford, some others) and the price will rise to around $350.
Can low tire pressure cause ABS light to come on?
The short answer is yes, low tire pressure can cause your ABS light to come on. The ABS (anti-lock-braking) system is responsible for maintaining contact with the road when braking. This suggests that you may have low tire pressure in one of your tires.
Will low brake pads cause ABS light?
This light illuminates in the dashboard where there is a brake-related problem. So you might ask, Can worn brake pads cause ABS light to come on? No! Your brake pads are not identified as part of the ABS, the ABS light will not come on when they are worn.
What happens if I remove the ABS fuse?
In summary, the brakes will operate as normal, but the vehicle will not have ABS engage in a situation that would otherwise operate ABS. This could result in locking of the wheels, increasing stopping distance and more importantly, affecting the ability to steer when braking and locking the wheels.
Where are the ABS sensors located?
The ABS sensor is typically located in each wheel hub/rotor on a four channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential.
Why does my emergency brake light come on randomly?
When your brake light comes on, your car is letting you know that either your vehicle is low on brake fluid, the emergency brake is activated, there’s trouble within the ABS unit, or there’s a problem with the sensors. Most vehicles have a sensor that confirms whether the parking brake is engaged or not.
What should the driver do if the brake warning light comes on while driving?

Can Dirty brake fluid cause ABS light to come on?
One of the causes of this internal wear could be the dirt brake fluid. This could make ABS light to come on.
Can rusty rotors cause the ABS light to come on?
The sensor ring for the ABS tells the system if the wheel is turning. It is basically a series of ridges, like a gear. It is not part of the rotor. If your ABS is activating because of rust in these gear-like teeth, it would be making godawful ABS noises, not brake judder.
Can AutoZone check ABS light?
Unfortunately, the only way to check whether or not the problem is with the ABS is to go and get the codes of your car read. AutoZone can scan your codes as part of our Fix Finder service, or you can do it yourself if you already have a scan tool.
How much is a new ABS system?
An ABS control module replacement can range from $320 to over $1,000. The wide price range isn’t really driven by labor cost, which will typically be around $80-$120. It depends on how much the control module costs and how difficult it is to source.
What causes Stabilitrak and traction control light?
When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack.
Can a bad brake caliper cause ABS light to come on?
So the short answer is YES, a sticking caliper could cause the ABS/Traction Control lights to come on.
Can I drive without ABS sensor?
Nope, you will only notice any difference if you need to brake very hard. In road cars the primary role of ABS is to retain some steering control during emergency braking which is a pretty rare event. In icy conditions it doesn’t do much and can actually detract from braking feel but does no real harm.
What fuse controls ABS light?
This is controlled by the anti-lock fuses and relay. The first fuse (a 10 amp fuse) must be good in order for electricity to flow to the relay, and the relay must function to provide power to the second fuse (a 30 amp fuse). This fuse must be good as well in order for power to flow into the entire ABS system.
