ABS CONTROL OPERATION

• When the dynamic stability control (DSC)/roll stability control (RSC) control module (CM) determines wheel slip
conditions based on the signals from the antilock brake system (ABS) wheel-speed sensors during braking, the
DSC/RSC CM operates the DSC/RSC hydraulic unit (HU) inlet and outlet solenoid valves, reducing and
maintaining brake fluid pressure in accordance with the wheel slip factors. Then, when the wheel slip condition
has passed, brake fluid pressure is increased and maintained, ensuring braking with a constantly stable brake
force.
