Abs and brake light stay on,brakes ok
The Brakes may seem to work okey, but you have an
ABS Braking System light on- indicating a system fault,
just like any other check light you get
Do you not check for codes almost the same day any dash light
or check light comes on?
It will bite you some day-- if you ignore the reason they are there
Could be a wheel speed sensor.... most common failure on ABS equipped vehicles
SOURCE: abs light stays on, but
The ABS warning light means there is a malfunction in the anti lock system on the brakes. This will not affect the conventional braking system on the car which will continue to operate normally.
The car is safe to drive as long as you recognize that it will now be possible to lock up your wheels under hard braking or when braking in slippery conditions where the tires have poor grip.
The problem with the ABS malfunction is that you no longer have an anti -lock assistance on the brake system so in certain conditions, such as on a wet road, you will be able to lock up the wheels on the car when you brake hard. The anti-lock system identifies and retards lock up (by releasing brake pressure on a wheel or wheels) and allows the wheels to keep turning slowly even when you have full pressure being applied on the brake pedal.
The ABS system relies on sensors and if one or more fails you will get an ABS warning. It could be a faulty or dead sensor but it is impossible to say without testing and inspecting the vehicle.
The ABS has it's own fuse so you can check the fuse box in the car to ensure the fuse has not blown. The fuse location is shown in the car's owner's manual. A blown fuse would trigger a warning.
You should take the car to a competent brake specialist to have it checked and the problem rectified.
It's much safer to have the ABS in operation.

If the light is not on it may not be the ABS that is pulsating on slow braking but it may be that your have warped brake rotors, even if the rotors were replaced with the pads the new ones may be warped already, we always check new rotors on a brake lathe before installing them because we have seen this happen many times

I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.
I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.
Thanks Fixya and all contributors

Its probably how your bleeding your brakes, but first make sure the bleeding nipples are facing upward. You should bleed diagonaly, front pass wheel then rear driver wheel. Then front driver wheel and rear pass wheel. The abs light has its own computer your have to get it scanned to clear the codes and turn off the light
