Brake system fault. Must troubleshoot. Recommend starting with brake fluid reservoir. Then check all brakes for leaks.

SOURCE: abs

Rex08, have you checked the bulbs? This truck is rare in that the ABS light will come on when the brake light bulbs go out.

If the lights are on all the time check the adjustment of the switch on the pedal. Don't adjust it too far in, you will have slight brake application while you are driving which is not good.

SOURCE: Abs/Brake Light ON, although new brakes, ABS still works

I would suspect a speed sensor.

SOURCE: 2004 Lexus SC 430 brake & ABS light comes on without braking

Well ABS stands for Anti-lock Braking System. The reason that kicks on is so your brakes don't lock up on you on certain terrain so that's not bad. But you said your brake lights are bad, check the wiring to them for any bare wiring to make sure none of the metal is hanging out of the insulation rubber.

SOURCE: abs and brake lights comes on

What you will need to do is have the system scanned for codes. Your local Auto Zone or Advanced Auto will scan the vehicle at no cost for you. Write the code numbers down and reply back.
When both lights come on, it is indicating one of the ABS sensing components is not operating properly. Your base brakes will be fine, however the ABS function will not work properly. No danger of base brakes not stopping the vehicle.
My guess at this point would be a wheel speed sensor faulty, but again, only a guess until you get the codes scanned.
Get the codes and let me know.
Regards,

I am driving a 2005 Dodge Caravan and the Abs light has come on. What doe sit mean and what should I do?


It means there is a fault somewhere in your abs system. While the light is on you will not have anti lock brakes. It just means you will resort to the old style of brakes before abs. It will not harm anything .but is something i would have checked out.

What do i do when the anti brake like has just come on. and what does it mean when the trac light is on?


ANY TIME ABS LIGHT OR TRAC LIGHT COMING ON THAT MEANS EITHER ONE IS NOT WORKING NOT GETTING NO OR ENOUGH POWER.CHECK ABS FUSE AND RELAYS. IF RELAY AND FUSE OKAY.MAKE SURE YOUR ALTERNATOR VOLTAGE OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS IF 11.0 VOLTS DUE TO VOLTAGE REGULATOR FAILURE. THAT WILL CAUSE ABS AND TRAC LIGHT TO COME ON.IF ALTERNATOR CHECKS OUT OKAY.TAKE VECHICLE TO GARAGE OR DEALERSHIP THEY HAVE TO SCAN THE ABS BRAKE SYSTEM.

2001 Buick Lesabre ABS light stays on even resetting the system. brakes are good and responding just the light coming on and off.


What this means is that the abs module is seeing a problem in the abs system.This has nothing to do with the regular brakes.What you need to do is get the codes from the abs module and this will help in finding what could be causing the light to come on.When the abs light comes on the regular brakes will work normally but your abs brakes will be disabled.Let me know what codes you find and I can help or explain what the cause could be.Good luck.

CHECK ALTERNATOR OUTPUT IT SHOULD BE 13.5 TO 14.5 VOLTS WITH ENGINE RUNNING.IF VOLTAGE LOWER 12 VOLTS THAT WILL CAUSE BRAKE AND ANTI LOCK BRAKE LIGHTS TO COME ON BECAUSE THAT NOT ENOUGH POWER FOR ABS BRAKES OPERATION.IF ALTERNATOR GOOD.BRAKE AND ABS LIGHTS ON ALSO MEANS LOW BRAKE FLUID LEVEL CHECK BRAKE FLUID LEVEL.ALSO. YOU HAVING BRAKE FAILURE.YOU NEED TO HAVE GARAGE OR DEALERSHIP CHECK BRAKES SYSTEM.BEFORE BRAKES COMPLETELY FAIL.

ABS LIGHT COMES ON AND DISENGAGES THE ABS BUT


When the ABS light is on the ABS system is deactivated. Meaning, when the abs is light is on and you brake, the tires will lock up with heavy braking.

Escapes have a common issue of the ABS excitor rings cracking causing ABS problems. Sometimes it activates on almost every brake application. It may set a code in the ABS computer for an intermitten wheel speed sensor or no wheel speed signal. Check all the "rings" on the outside of all four axleshafts. If none of the rings are cracked it is likely a bad ABS wheel speed sensor.

When 'ABS" light comes on, vehicle has no power...


if the abs light comes on, it means you have an abs issue. If you do, the brakes revert to normal power brakes with no ABS function.

WHen the vehicle has no power, do you feel the brakes slowing the car or do you hear the abs chattering?
