Steering Angle Sensor Module (SASM)
WARNING: This page is about a different car, the 2011 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles equipped with EPAS are also equipped with a SASM which has no internal circuitry and does not contribute in any way to AdvanceTrac® functionality. The SASM is used to provide structural support for the clockspring and for canceling the turn signals.
