VDC OFF Switch:
1. Allows the driver to temporarily disengage the VDC
2. In "temporarily disengaged" status, the VCD OFF indicator light illuminates
VDC = Stability control. I'll agree that pressing the button does not disable ABS, but it does disable TCS AND VDC.
Front diff open
Center diff is viscous coupling (can act like a LSD) and is not controlled by the ABS system
Rear diff is open and is not controlled by the ABS system
