C0187 2018 GMC Sierra Code - Multi-Axis Acceleration Sensor Circuit
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 Multi-Axis Acceleration Sensor (Internal to the Inflatable Restraint Sensing and Diagnostic Module), Multi-Axis Acceleration Sensor harness is open or shorted, Multi-Axis 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.
