Why would the anti-lock brake lights be on?

I had this problem with my Chevy Venture van after I did work on the gas tank. I thought I might have damaged a wire. I did some research and found out more on how it worked. Anti-lock brakes work by using sensors on each wheel to measure the speed of the wheels. for a detailed explanation, check a site like howstuffworks.com What i learned said the anti-lock brake light comes on if there is a problem in the system. Mine turned out to be a disconnected plug to on of the sensors. Hope that helps. When the comes on and stays on, it is telling you that it is not operational. While you mechanical brakes and parking brake will still work, the ABS will not. There can be a multitude of possible problems. There may be a bad sensor, a bad connection as listed above, a bad harness, or worse of all a bad ABS module. Lack of brake fluid flushes seem to play a factor in the fialure of these expensive little animals. It is not uncommon to see the units costing $1500.00. I am a firm believer in Anti-lock Brakes. If I didn't have them one particular evening, I wouldn't be here typing this out today.

Antilock Brake Light comes on and stays on when the ABS computer detects some problem with the antilock brakesystem components. You will still have normal brake use, but the Antilock system will probably not work as an Antilock brake system is supposed to work. ABS system diagnostic code readers are available and are recommended for diagnostic purposes, however fixing ABS systems is perhaps best left up to the Pros. . .

No difference ABS, Antilock Braking System.

That function is handled by the antilock brake hydraulic unit.That function is handled by the antilock brake hydraulic unit.

Antilock Brake Module?

It's computer controlled, and applies and releases the brake in order to prevent wheel lockup.

It could be a fuse , a sensor , or some other problem with the antilock brake system ( as long as the red " brake " light in your dash is not on you still have " normal " braking )

No. BAS (brake assist system) and ESP (electronic skip protection) are part of the antilock brake system. They have nothing to do with the oxygen sensors.No. BAS (brake assist system) and ESP (electronic skip protection) are part of the antilock brake system.

frist the brake light looks like its on but its just the glow of the antilock light it is very bright. the antilock is on your rear axle needs replaceing.

2nd Gen. Ram Antilock brake lightIt is usually a sensor on top of the rear differential that causes the antilock and parking brake lights to remain on. There are some electical wires that plug into the front of it and it has a probe that goes into the differential. It also has a bracket that holds the brake lines in place. Removal of the spare tire gives ample room to gain access. Some times cleaning the probe fixes the problem, usual it is best to replace it compleatly.

NO, but it would be a good idea to have your Antilock Brake System checked.

An ABS brake is another term for an antilock brake, a brake fitted to some vehicles to prevent skidding and compensate for overbraking.

Most likely no brake lights would be due to a faulty switch on the brake pedal or a bad fuse.

The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.

check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal

If the ((ABS)) Light is on then it's a good thing indicating that the Antilock brakes sensor is in good condition. I too have a 2002 mountaineer

The bulb is burnt out. If the problem was a fuse, then all brake lights and probably the dashboard lights would be out as well.

The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.

It is on because there is a problem with the Antilock Brake System (ABS).
