If you start the vehicle and the ABS light never goes out it is failing its self check test. Typically a bad wheel speed sensor will cause this.

If the light comes on when you start it, goes out shortly after, but comes on after driving for a little bit than the problem may be a little bigger. Wheel speed sensors could still be the problem but you could also have issues with wheel bearings, exciter rings, solenoids, or modules.

The best thing to do is have the ABS module scanned for codes. This will narrow down the possibilities significantly. Post the codes here and we'll be more than happy to guide you to the next step.

These vehicles have a recall on the ABS system for faulty wiring. You may want to check with your local dealer to see if your vehicle is included.

SOURCE: 2001 S Type Jaguar ABS and Traction Control fault lights on

Hi First I suggest that you get a diagonostic check on ABS system. and then a visual inspection of the brakes. Warped brake rotors do not make noice, but the steering will start to judder when brakes applied at around speeds from 40 up . Possible cause that the vehile picked up something from road such as nylon/ plastic/stone Mike

My dash light abs and brake lights came on as well as internal lights.why


What I would do: get a fault code reader on you truck. Autozone will put one on it for Free. Record the codes and use a Haynes manual and on-line research to assist in diagnosis. You probably have several simultaneous issues that are affecting one another. Usually an ABS warning light comes on, when the vehicle isn't moving, when a wheel sensor or sensors is bad and/or the ABS computer module is bad. Rebuilt modules can be had for $100 or so. Sensors are easy to replace once you determine either with a specific fault code or with a multimeter which ones are faulty. If the vehicle is moving and the ABS light comes on when you are pressing the brake... this is normal when the ABS is activated and the vibration is felt through the brake pedal.

How do I identify the cause of an ABS Fault?


First thought is that if you have a judder from the brakes you may have a warped front disc. The ABS system sensor may be picking this judder up and converting it to a fault.
A warped disc would spin and catch then spin and catch again rather like the rapid on/off braking that ABS does. This 'could' be the judder you feel and should be especially noticeable when braking and barely noticeable when driving with the brakes completely off.

2007 GMC Canyon ABS Fault - Originally ABS Fault started when making a sharp right turn. (ABS Fault light only). Stopping and restarting would clear 'fault' until next hard right. Later, occasional metal...


id check your caliper to see if the piston is compressing all the way if not check your fluid it should be clean not brown or if you have been through large amounts of water if it has gotten into the brake system and check your bleeder valve to check if it has rotted or come lose or if you have a break in the lines or air, most likely your caliper is failing to compress.

Esp light flashing


There could be one or more of several reasons why the ESP light has illuminated on your Smart car...
For example, you could have a fault with dirty reluctor rings on the Abs system - faulty Abs sensor/ s ... a fault with the brake light switch - a fault with the steering angle sensor -- even a software glitch / issue in the control system...
The above are known issues that can and do cause the Esp light to come on.
What you will have to do is have the car connected to a dealer diagnostic machine - This will run a full diagnostic test and fault code read - to see why the Esp light has come on and quickly and efficiently find the right cause - and then it can be sorted out, whatever it transpires to be.
You really cannot do much on a Diy basis on these for this fault. You can check the reluctor rings as mentioned above and the wiring to the ABS sensors. The abs light will often come on to with the Esp light - but not always. Dont check these these things with the Ign On....
Too, you can check to see if the brake lights are working - if they are not - thats a definite indication of brake lamp switch failure which will cause the Esp light to come on - but while its worth checking - even if the lights do work - it doesn't always follow the switch is ok - it has a dual function - brake lights and engine management circuitry...
At which point, if you have found nothing - you will have to have the diagnostic done as above to find the fault.

My abs warrning light is showing on my bmw 316 and does not go out..


On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system.

What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on. This should have no effect on normal braking. Even so, ABS will NOT be available in an emergency situation or when braking on a wet or slick surface.

CAUTION: If the brake warning light also comes on and remains on while the ABS warning light it on, it signals a serious problem. Your vehicle may not be safe to drive. The brakes and ABS system should be inspected immediately to determine the nature of the problem!

If the ABS light comes on momentarily then goes out, the nature of the problem is usually minor and the ABS system usually remains fully operational. Some vehicle manufacturers call this kind of fault a "nonlatching" fault (meaning it isn't serious enough to disable the ABS system).

Regardless of the type of fault that occurred to trigger the ABS warning lamp, a special "code" is recorded in the ABS module's memory to aid in diagnosing the problem. On some vehicles this code can be retrieved by putting the ABS system into a special diagnostic mode. The code is then flashed out through the ABS warning lamp. The code number refers to a diagnostic chart in a service manual that must be followed to pinpoint the faulty component. On other applications, a special "scan tool" must be plugged into the vehicle's diagnostic connector to read out the fault code.

My ABS light came on with out me useing the breaks is this normal?


No that is not normal. When the ABS light comes on and stays on you have a fault present in the ABS system and the ABS control module is alerting you to this problem. As long as the light is on the ABS brake system us disabled and you have in effect standard non ABS brakes. In order to find out what the fault is the ABS system must be tested by using a scanner, it will have a code in memory.

Why wont my ABS light on the dash wont turn off even after I changed the brakes?


the ABS light doesn't come on because u need a brake job, it comes on when it senses a failed part like a wheel speed sensor, in order to determine exactly what part is keeping the light on and disabling the Antilock Brakes you will need a shop to scan the systems comuter for fault codes

Rr.ABS and the brake lights on


CHECK TO MAKE SURE WITH CAR RUNNING VOLTAGE AT THE BATTERY SHOULD BE 13.5 VOLTS TO 14.5 VOLTS. USE A DIGITAL VOLT METER TO CHECK VOLTS AT BATTERY. WITH ENGINE OFF BATTERY VOLTAGE SHOULD BE 12.5 VOLTS. IF NOT ALTERNATOR NOT CHARGING BATTERY.THAT WILL MAKE ABS AND BRAKE LIGHTS COME ON AND A FAULTY BRAKE LIGHT SWITCH WILL ALSO CAUSE ABS AND BRAKE LIGHTS COME ON.IF ALL LOOKS GOOD.HAVE THE ABS BRAKES SCANNED.IN THIS CASE YOU ARE HAVING BRAKE FAILURE.BECAUSE WHEN BRAKE LIGHT COMES ON THATS WARNING BRAKE FAILURE BECAUSE THE BRAKE MASTER CYLINDER AND ABS UNIT IS TOGETHER AS ONE.NOT SAFE TO DRIVE.COULD LOSE BRAKE CONTROL AT ANY TIME TOW IT IN.

ABS Light


My Answer:

It appears that very possibly you have a bad ABS wheel sensor either up front (right or left side) if you only have Disc Brakes in the front and drum brakes in the rear, or else a bad ABS sensor in one of the rear wheels with a 4 wheel Disc Brake system.

The damp part was the giveaway, as if it's doing it in dampness then surely it'll do it when wet as well. That is a given!

Esp if it's not doing it in DRY weather.

If it's not a bad (leaky as from moisture getting inside it) ABS wheel sensor then it could just be chaffed wires coming off from one of the wheel sensors that's shorting to ground. Esp when it gets wet as from dew point moisture or from rain. Possibly, but somewhat doubtful.

If you just had the brakes serviced recently, and the problem started shortly there afterwords then I would definitely suspect the (a) wheel sensor.

If it's been a problem from DAY ONE, or even under the original warranty period then it needs to be fixed for FREE under that original warranty. No bones about it.

What's probably happening is that the sense wire from whichever wheel sensor is bad is shorting out and causing the ABS FAULT LIGHT to come on. I seriously doubt that you will get a CHECK ENG code fault, as this is purely a BRAKE ABS fault.

One thing you might do is pull the main wiring harness connector off of the ABS unit itself and check it for MOISTURE on the contacts. If any is found then that is your problem point.

Even if no moisture is spotted get a can of waterproofing spray from you local automotive parts store and spray out both sides of the ABS wiring harness connectors.

Since this is purely a MOISTURE related ABS Warning Light issue/problem it has to be one or the other and nothing else.

Sometimes it's best to check for this issue at night with a good bright LED type light, as then the MOISTURE will show up better then in the daytime.

If this fixes the problem please post the result.
