The computer codes for the ABS are not a part of the typical code scanner; you may need to take the vehicle to a dealer or specialty shop to have someone read the code for you.
The computer code will let you know why the light is on and let you know if it's something serious, such as a faulty ABS computer or something minor, such as low brake fluid.

    Our ABS light has been coming on for awhile now and today we got a "low brake fluid" warning light on the dash so if the comment is correct it should solve our ABS light issue on our dash. Will let you know in a few days ....

SOURCE: abs light stays on

I had this exact same problem, on a older bronco II. You need to get the ABS computer reset. You can either take it in or buy a computer your self. There are even packages that will allow you to use your own computer and just hook the car up to your lap top or desk top if you can get a cable long enough.

I never had mine done, because back then the computers were so expensive. I never caused a problem because it was only in the braking system. Now they are pretty cheap and there are a lot of other cool things you can do with them. You can reduce your gas requirements and set it for pulling, racing, and fuel efficency on the fly now. Just at the touch of a button.

SOURCE: abs light/traction control light

You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.

SOURCE: 1998 Dodge Grand Caravan. Whenever

Reports say that this can be caused by cold solder connections in the centre instrument panel where the A/C controls are. Electrical system issue here manifests itself in instrument cluster. Fix is to remove 4 screws to access A/C stuff. Look for burnt or loose wiring / terminals on connectors in this area.. Re-solder or obtain used replacemnt terminal if needed, from junk yard. Mine is 1999 Grand Caravan. Intermittent failures then permanent with instrument cluster.

First suggestion is to take out the 20 amp fuse before you have a massive wiring problem from a burnt harness. IT has a 10 amp fuse to protect the wiring and anything over will set the car alight if there is a dead short.. Next run the fault codes to find out why the ABS light came on. Have a check done on the alternator and check the alternator drive belt and tension. I suspect that the alternator has insufficient out put to handle all the electrics and that means either the alternator or a failing battery.

My ABS light showin my my dash board and it was scanned my mitsubishi. Presently the light is still showing and when I break, I hear some noise as if the break pad is pad. I currently have new beak pad...


Hi,

New brake pads require 'wearing in' and may make a scraping sound for the first 50km or so.

Re ABS

First, I suggest you remove the PCM "Fuse" (in the main junction box, under bonnet) for 10secs, then re-insert. If you cannot find fuse, then disconnect NEG battery cable for 10secs. This will reset your PCM.

Start engine and allow to idle for 15mins (this allows the PCM to re-learn settings).

Drive car a short distance to determine if ABS light comes back on. If ABS light does come back on, then have the PCM scanned for fault codes. This will identify which ABS component is causing the (warning light) problem.

If light remains off (and the pads are worn in), but you still have scraping noise, then something else is causing this problem and will require further investigation.

Rear ABS Light/Rear brakes drag sometimes


The only moving parts on brake's are caliper's and master cylinder.The rest are just pipe's. Dosent sound like the master cylinder as the two back brakes should lock not one. It still sounds like caliper's. Can you be sure they have changed them If it were mine I would get someone independent to check they have done the work they say they done.

Abs light


I have the same problem with my '98 Buick Century. Its due to a bad ABS sensor wiring harness, in my case that is. A few other things can cause the light to come on. If its because of the wiring being bad like in my situation, you simply need to replace the wiring harness and possible the sensor itself depending upon where the damage is in the electrical circuit . The sensor's wiring goes bad usually because over time, water, dirt and road grime get into the wiring and other components of the sensor and cause damage or a electrical short somewhere. Corrosion is most likely what damaged my sensor's wiring, as I am from the Northern U.S. where salt is spread on the roads in the winter to deal with icy conditions.

These ABS sensor wiring harnesses seem to be prone to water infiltration. I first noticed the light come on during a heavy rain storm when I drove through a flooded roadway where the sewer drains clooged up. Since then, every time I would drive through a relatively deep puddle, the light would come on until I killed the engine and restarted the car.

This periodic tendancy for the light to come and go like this is most likely due to a temporary short in an electrical circuit somewhere in the sensor's wiring. The code is thrown and stays active until the car, and ECM, is restarted. But over time, the water that is getting into the wiring harness or the sensor's wiring itself is causing any ferrous metal (like in the wiring) to rust (corrode). The salt on the roads in the winter where I live only hastens the corrosion. Now, its to the point where the sensor or its wiring is so badly damaged that it permenantly throws a code. I need to replace the sensor and/or the sensor's wiring harness to keep the code from coming on.

Keep in mind that while the light is on, your anti-lock braking system will not engage when you need it to. For your information, if you start sliding and your ABS isn't working (your ABS light is on) you should pump your brakes the way you would in a car without ABS brakes. It goes without saying that you do not pump your brakes when your ABS is working properly.

I'm not sure if your situation is the same as mine. Keep in mind that you have 2 ABS sensors. Their wired from your front wheel bearings (hubs) to their respective wiring harnesses which are stationed to both front lower control arms via a metal clip on the back of the harness. I know which one is bad in my car because I found it disconnected from the control arm at one point and also because it is the side that gets wet when the code was thrown temporarily in the past. You may not have the same insight to your situation as I do in mine. Also, other things can cause this light to come on. Trapped air inside the ABS modulator assembly is one example. If you replaced the master cylinder, a brake line or valve ahead of the ABS modulator, or if you had to replace the modulator or high pressure accumulator, air can get inside the ABS modulator assembly.

Air can be very difficult to remove from an ABS modulator assembly because of all the nooks and crannies inside the unit. The modulator may have eight to 10, or more, ABS/traction control solenoid valves, plus various check valves and dead-end ports. Some ABS modulators have special bleed screws to help you vent the trapped air when bleeding the system. Others do not and require the use of a scan tool to cycle the ABS solenoids while you bleed the system.

Some low end shop mechanics more than likely will not know how to diagnose and repair this problem and tell you to take it to the dealer and pay the dealer prices. Its expensive, but its what I suggest you do if you've had any major brake work done lately and now your light won't go away. If a shop can be blamed for the trapped air, I suggest you go about getting them to pay to have it fixed, either by simply asking or by legal action.

A few other things can cause the ABS light to come on in your vehicle. The best way to pinpoint the problem is with the use of scan tool. I suggest either taking your car to a Buick dealership or to a mechanic who you know for sure is knowledgable with the specifics for your car. It wouldn't be a shock to me, however, if it ends up just being a bad sensor or a rusted wire somewhere. This seems to be the most common cause for the ABS light to come on. If the sensor itself is bad, which is common, then you have to replace the entire wheel bearing or hub assembly as it is properly referred to. They are kind of expensive (last I checked, it was like $140 per wheel bearing). The actual ABS sensors are part of the hub assembly and cannot be replaced seperately. Hope I was able to help.

I had the same problem. Abs light would come on and I would lose all dash instruments. Hit a bump on the road and abs light would go off and dash would come back on. What I did to fix problem, lol I slaped the dash just to the right of instrument panel and it all came back to life. There seems to be a short there, and I slaped it back 3 times in a week and now for the last month it has stayed on.
