C0186 2017 GMC Sierra 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.
