2 Automatic Traction Control (ATC), Deep Snow and Mud Switch and Roll Stability Control (RSC)

Meritor WABCO Maintenance Manual MM-0112 (Revised 07-05)
RSC
Roll stability control is an option designed to assist drivers in
managing the conditions that result in commercial vehicle rollovers.
When RSC senses conditions that may result in a rollover, it reduces
engine torque, engages the engine retarder, applies enough
pressure to the drive axle brakes and may modulate the trailer
brakes to slow the vehicle down. Like ATC, RSC works automatically.
The driver does not have to select this feature.
RSC uses many of the same components used by ABS and ATC.
A second solenoid valve, the RSC valve, controls the trailer service
brakes during an RSC event. This is a stand-alone valve that is not
available as part of the ABS/ATC valve package. Figure 2.5.
