Lateral Acceleration Sensor
The lateral acceleration sensor is mounted in the left "A" pillar. The sensor provides the DSC control module with an input signal that corresponds to the degree of lateral acceleration ("G" forces) acting on the vehicle.
The sensor is a capacitive type with two capacitive plates (one fixed and one moving). Under the effect of lateral acceleration, the one plate moves in relation to the fixed plate. This results in a voltage signal being produced in proportion to the degree of lateral acceleration.
The voltage signal output of the sensor to the DSC control module ranges from 0.5 to 4.5 volts. When the vehicle is stationary, The standing voltage from the sensor is approximately 1.8 volts.
This signal is used in conjunction with the yaw sensor input to determine the degree of DSC regulation required to maintain the vehicle's stability.
