ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.

If light turns off on startup, and comes back on when you reach some speed, usually you need to check the wheel sensors. You test them unplugging the sensor located behind the wheel and testing it for continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.

It should come on for a few seconds with the other lights, but should not stay on for a minute.  If you get an intermittent ABS light it could be a speed sensor or more likely the ABS module.  If you get an ABS light along with a flashing arrow light, traction control light, or  speedometer and odometer goes out, then it is just about guaranteed to be an ABS module issue.  There are online sites that will rebuild ABS units for around $150 or less.  They are pretty easy to remove and install yourself with the right socket.  Google "Victor Rocha".  His site has good information on the procedure and he is well trusted for his rebuilding jobs (I have no affiliation to him or the site).

actually it could be something as simple as low on brake fluid. check this and then check to make sure you do not have worn brake pads on the tires this can also set a code when one tire stops quicker than the other

SOURCE: Abs and trac light on, abs vibrates car when braking

These two circuits are linked together and you probally need a ABS MODULE and possibly a rotor and they are pretty cheap on e-bay
