Anti lock brake light on

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.
