The anti lock brake light is on and not functioning. My first thought is have the anti lock brake system bleed, I have bled brakes before but never this. No codes, other than this issue the car runs great and stops okay.

Hi,

If the system hasn't been opened, there shouldn't be a need for bleeding. In most cases, the problem is related to a faulty wheel speed sensor.

Take a look through this link. It explains how to test the sensors. You will need a multimeter or voltmeter.

I attached pics below showing the locations of the sensors. There will be one at each wheel.
