pull off some codes using a blink code reader, that might help you...

 

One easey check is the OVP relay and especially the 10A fuse on top of it.

 

If the ABS light only comes on after you start driving, the problem is unlikely to be the OVP relay. If the light comes on and stays on as soon as you star the car, as above, check the fuse on the OVP and if the fuse is good, replace the OVP. If you still have the ABS light after replacing the OVP (either at startup or after driving), it is likely you have a bad wheel sensor. Check the connectors on each of the the sensors for corrosion or looseness. Measure the resistance of each sensor at the connector - they should be on the order of 100 ohms. If it has a very high or infinite resistance, or If it has near zero resistance, the sensor is bad. Lastly, you may have a failed ABS control unit, but that is a diagnosis of exclusion.

 

I vote wheel sensor, or void in the brake system. Check sensors and or bleed brakes to get air pocket out.

 

Was the brake system pressure bleed after installing all the new parts?

 

Try installing a new brake light switch.

I went through all kinds of stuff and this fixed it for me.

 

If the light comes on before you begin driving, it is probably the power suppy module. I had your same problem and after replacing the sensors,fuses,etc., the problem turned out to be the power supply module to the ABS system. The test is if the light goes on as soon as you turn on the ignition and stays on. Good luck.
