Trailer Sway Control

2007 Ford Escape Base, 2.3 Z, FWD, AutomaticSECTION Trailer Sway Control
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.

Trailer sway control is a unique function in the AdvanceTrac® with RSC®  system that will recognize and aid in reducing trailer sway. The trailer sway control system continually monitors the steering wheel rotation sensor and the yaw rate sensor to identify specific, increasing yaw oscillations that occur during a trailer sway event. If the trailer sway event exceeds certain, programmed parameters, the ABS module and the HCU  will modulate brake fluid pressure to specific brake caliper(s) and the PCM will modulate engine torque until the trailer sway is reduced below the programmed parameters.

When the trailer sway control system activates, the vehicle will produce the same noticeable symptoms as it does when the traction control and ESC  systems activate. In addition, the message center will display TRAILER SWAY, REDUCE SPEED.

The trailer sway control system will only activate when the vehicle speed exceeds 64 km/h (40 mph). The system can be disabled during any key cycle. Refer to the Owner's Literature for information on disabling the system. The system will be re-enabled when the ignition key is turned to the OFF position and back to the RUN position.

Trailer sway control is not available on hybrid vehicles.
