Code C0187 Chevrolet Description

The Yaw Rate, Lateral Acceleration, and Longitudinal Acceleration Sensors are combined into one Multi-Axis Acceleration Sensor, internal to the Inflatable Restraint Sensing and Diagnostic Module. The Multi-Axis Acceleration Sensor communicates via serial data with the Electronic Brake Control Module (EBCM). The Electronic Brake Control Module activates the stability control function depending on the Multi-Axis Acceleration Sensor input. The Inflatable Restraint Sensing and Diagnostic Module uses the Multi-Axis Acceleration Sensor to determine if the vehicle is in a rollover or near collision incident. The Diagnostic Trouble Code (DTC) will be set if the Multi-Axis Acceleration Sensor signal is out of the specified range.
