Here's what causes this: A blown fuse for the system, A wheel-speed sensor that is damaged or covered by road grime, A broken wire between the sensors and the ABS controller, An ABS controller that has stopped working. A pump and valve that apply the right amount of brake fluid pressure to each wheel to prevent locking can also trigger an ABS sensor warning light when those items go bad. If the red warning light for the regular brakes comes on, that typically means your vehicle is losing brake fluid or the brakes are so worn that you don't have normal stopping power. Either of those situations warrants immediate attention and possible repair work.
Nowadays, auto electrical repairs are getting more and more complicated and are already pressuring the boundaries of contemporary technology. However, they are fundamentally the same with their design three decades ago. An informative general idea of your vehicles electrical structure would be an excellent kick off. The most important mechanism of your cars electrical system, the battery and the alternator are explained underneath, in conjunction with some troubleshooting tips.
You can speed the tune-up process by being ready to describe what happens and when (such as whether your car hesitates when the engine is cold or when passing at highway speeds), any sounds you hear and what you feel when your car’s "illness" shows up. One caution about lower fuel economy: You should expect it to go down at least a little during the cold months, and maybe a lot. Colder temperatures make your engine and charging system work harder. In addition, winter gasoline blends have slightly less energy content than summer blends, so they don’t deliver as many miles per gallon. A tune-up won’t make Old Man Winter, or his effects, go away.
From the first steam powered coaches to today's super-cars, an automobile is a vehicle that undergoes constant changes and improvements. The first cars that were invented could barely replace the horse, were not reliable and didn't show any promising future. But people who were visionaries kept the idea alive, pressured forward thus making the car a irreplaceable part of our lives.
