Electronic Stability Control

Hank was wondering how the system works.
This doesn't explain it but Ford says:

AdvanceTrac® with Roll Stability Control™ (RSC®) uses a combination of reduced engine power and selective wheel braking to help the driver maintain control.* Corner too quickly or swerve to avoid an object and RSC® will automatically use its gyroscopic sensors to measure vehicle roll and turning rates, then apply the proper response to help keep your vehicle under control.

Standard on Super Duty® Pickup and SRW Chassis Cab, electronic Trailer Sway Control helps keep whatever you’re towing doing what you want it to do, not what the forces of gravity and inertia want it to do. This control is accomplished through selective wheel braking and reduced engine power to help keep your trailer behind you through high winds, turns and rain-soaked roads.*
