An ABS light after a brake job could indicate that the technician disconnected a wheel speed sensor, or even just did not properly clean it. It could also be caused by the caliper piston being forced into its bore without opening the bleeder screw, which forces sediment from the caliper into the ABS valve body, potentially causing problems.
Disconnect the battery for 15-30 Mins and it will reset automatically.
if it is your brake light blinking then you may need to check the rest of your braking system ,, ie. fluid level,pressure switch, and wear sensors... Turn your ignition key to position 2 (do not start the car). Wait approximately 45-60 secs. and it should reset the yellow dash light.
check fluid level
Basically fix the problem with the brakes, check to see that the fluid is full and if it is you need to get the complete brake system checked out.
your park brakes are on
airbag light is on dash
you have air in your brakes bleed them
check your fluid levels, some vehicles will need brake bleeding but some may have brake sensors which that light that is lit up on your dash is for when the brakes were replaced the sensor may not be installed correctly go back and replace the sensor
It could be a fuse , a sensor , or some other problem with the anti-lock braking system ( as long as the " brake " light in your dash is not on , you still have " normal " braking ) it means air brake system and it has something to do with your brakes. unhook the battery cable and let it reset and that will tell you for sure if you have something wrong let it reset for 15 minutes
Trailer brakes.
After repairing the failure that caused the code, the lights will reset themselves.
