ROTATION RATE/TRANSVERSE ACCELERATION SENSOR
Located under the center console behind the MRS III control module, the rotation rate and
transverse acceleration sensor provides two inputs to the DSC control module. The sensor
is isolated from body/chassis vibrations through its rubber mounting.
For rotational speed, the sensor produces a reference signal of 2.5 volts and a linear volt-
age signal from 0.7 to 4.3 volts. This linear voltage input signal is used by the DSC control
module as the degree of rotational rate (yaw).
The sensor also produces a linear voltage signal for the lateral acceleration (G-force) that
ranges from 0.5 to 4.5 volts. The DSC control module uses this input to determine the side
forces acting on the vehicle for DSC regulation.
