C0186 Chevrolet Code - Lateral Acceleration Sensor Signal

Quick Answer

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. Common causes include Faulty Lateral Acceleration Sensor (Internal to the Inflatable Restraint Sensing and Diagnostic Module), Lateral Acceleration Sensor harness is open or shorted, Lateral Acceleration Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0186 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 Lateral Acceleration Sensor signal is out of the specified range.
