Your VDC Vehicle Dynamic Control (VDC) is an automatic system that helps improve vehicle stability by automatically engaging brake pressure and/or engine torque.

The ABLS works all around when braking.

ABLS works in 2wd and 4WD hi and lo, although ABS is disabled in 4WDlo.
When you apply the brakes yourself ABLS does not work, which makes sense.
