The Yaw Rate, Lateral Acceleration, and Longitudinal Acceleration Sensors are combined into one Multi-axis Acceleration Sensor. The Multi-axis Acceleration Sensor is located internal to the Airbag Sensing and Diagnostic Module.

The readings are compared to an internal calibrated value, so it knows if the vehicle is having an instability condition to activate the stability control. The Diagnostic Trouble Code (DTC) will be set when the vehicle is driven in a straight line the Multi-axis Acceleration Sensor, the Steering Wheel Angle Sensor, and the vehicle speed correlation is not recognized after a distance of 2.5 km (1.5 mi).
