Introduction to DSC

Combined Rotation Rate/Lateral Acceleration Sensor (Bosch DSC III 5.7)

On DSC III (Bosch 5.7) the Rotation Rate sensor and the Lateral Acceleration sensor have

been combined into one unit. The sensor is located under the driver’s seat and it is small-

er in size and weight and is isolated from chassis vibrations through it’s rubber mounting.

The sensor provides the same information as the two spearate sensors used on DSC 5.3.

It receives the same power and ground from the DSC control module.

For rotational speed, the sensor produces a refernece signal of 2.5 volts and a linear volt-

age from 0.7 to 4.3 volts. This linear voltage input signal is used by the DSC control mod-

ule as the degree of rotational rate (yaw).

The sensor also produces a linear voltage signal from 0.5 to 4.5 volts. The DSC control

module used this input to determine the side forces acting on the vehicle for DSC regula-

tion
