ABS with AdvanceTrac® and Roll Stability Control (RSC®): Notes

The ABS with AdvanceTrac® and Roll Stability Control (RSC®) system consists of the same components as the conventional ABS above with the following additional components:

• Stability control sensors - located inside the Restraints Control Module (RCM) and consist of the following sensors: yaw rate, roll rate, lateral accelerometer, and longitudinal accelerometer. The sensors are integral to the RCM and cannot be serviced separately.
• Steering Angle Sensor Module (SASM) - vehicles that are equipped with Electronic Power Assist Steering (EPAS), but without the Active Park Assist feature have a SASM which does not have any electrical components inside. It is only installed to provide structural support for the clockspring and for turn signal canceling. On these vehicles, the steering wheel rotation and angle information (an input for RSC®, Trailer Sway Control and Active Park Assist functions) is sent from the Power Steering Control Module (PSCM). Vehicles with the Active Park Assist feature have a fully functional SASM and  receive steering wheel information from the SASM.
• Steering wheel rotation sensor, vehicles with Hydraulic Power Assist Steering (HPAS) only - located on the RH side of the clockspring and is serviced separately from the clockspring assembly. The sensor provides steering rotation information to facilitate RSC® and Trailer Sway Control functions.
• Steering wheel rotation sensor ring, vehicles with HPAS only - located on the clockspring and is serviced with the clockspring assembly.
• Traction control switch - located in the instrument panel finish panel and is serviced separately from the finish panel.

The AdvanceTrac® with RSC® system is made up of the following 3 distinct vehicle systems:

• Traction Control System - helps to avoid excessive drive-wheel spin and loss of traction.
• Electronic Stability Control (ESC) - helps to avoid skids and lateral slides.
• RSC® - helps to avoid vehicle roll-over.
