Maybe your abs wheel speed sensors are dirty. In some cases the ring gets messed up with rust, causing it to be too close or too far from the sensor.
When cornering there is a bit of flex on the hub and you might be just barely in range of a sensor.
Not sure where you can log the wheel speed sensors but that might be worth a shot to do while cornering left to see if there are spikes or drops on a wheel relative to the others.
