Diagnosing anti-brake system warning light?
An ABS light (anti-lock braking system) that is stuck on doesn’t necessarily mean you need an ABS brake repair. The light is generally located on the dashboard on your control console next to the speedometer and gauges, and it could be triggered by issues other than problems with the anti-lock brakes. The light staying on can be caused by something as simple as the emergency brake or more complicated things like a loss of brake fluid and pressure or bad hydraulic valves.
Sometimes the emergency brake will not go down far enough and keep the light on, even though the brakes are actually not applied.
The emergency brake does not run on the same system as the main brake line, but if the E-brake is in working condition, it can still be applied in a situation where the main lines fail. It can also be applied as a preventative measure in areas with steep driving terrain. However, this light can get stuck on if the handle is notshut off properly. Check your E-brake to be sure that it is in the proper down position. Adjust a few times and see if the light goes off .
Alternatively, if the levels are topped off, it could be that you are losing pressure on one side of the vehicle, which can be dangerous. Losing this pressure can cause the brakes to fail while on the road, and the danger increases as the vehicle increases in speed, as the system will not be as effective in stopping the car.
