AdvanceTrac® With Roll Stability Control (RSC®): Notes
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The AdvanceTrac® system is made up of the following systems: conventional ABS, traction control and Electronic Stability Control (ESC). The Roll Stability Control (RSC®) system is an optional feature that works in conjunction with AdvanceTrac® to aid in maintaining vehicle stability. The AdvanceTrac® with RSC® system consists of the following components:
- ABS module - attached to the Hydraulic Control Unit (HCU), but can be serviced separately from the HCU
- Front wheel speed sensors - one sensor is located in each front wheel knuckle. The sensors are serviced separately from the knuckle
- Front wheel speed sensor tone rings - one tone ring is located on each front axle halfshaft and can be serviced separately from the front axle halfshaft
- HCU - which contains several valves (inlet, outlet, isolation and dump), and the hydraulic pump motor. It is mounted in the RR corner of the engine compartment on hybrid vehicles and in the LR corner of the engine compartment on non-hybrid vehicles. The HCU is serviced as a unit, but does not include the ABS module
- Rear wheel speed sensors - one sensor is located in each rear wheel knuckle, the sensors are serviced separately from the knuckle
- Rear wheel speed sensor tone rings - one tone ring is located on each axle halfshaft in AWD applications and is not separately serviceable. In FWD applications, the tone ring is part of the wheel hub and can be serviced separately
- 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 wheel rotation sensor - located in the Electronic Power Assist Steering (EPAS) steering column assembly, this component cannot be serviced separately
- Stability/traction control switch - located in the lower instrument cluster center finish panel and is serviced separately from the finish panel
