Common Symptoms

Stability control warning light on
Traction control disabled
Service StabiliTrak or ESC warning message
No stability control intervention in turns
ABS light may also be on

Probable Causes (Ranked by Likelihood)

Failed lateral accelerometer sensor Very High
Corroded or damaged sensor connector High
Wiring fault between sensor and stability module Moderate
Sensor mounting loose or rotated from correct position Moderate
Stability control module input failure Low

Step-by-Step Diagnostic Procedure

Scan for DTCs and view lateral acceleration live data
Locate the lateral accelerometer -- typically combined with the yaw rate sensor
Inspect the sensor connector for corrosion, water damage, or bent pins
Verify the sensor is mounted securely and oriented correctly
Roll the vehicle gently side to side while monitoring live data for response

Frequently Asked Questions

What does the lateral accelerometer measure?

The lateral accelerometer measures the side-to-side (lateral) G-force acting on the vehicle during turns. The stability control system uses this data along with yaw rate to determine if the vehicle is skidding or losing traction.

Is the lateral accelerometer a separate part?

On many modern vehicles, the lateral accelerometer is combined with the yaw rate sensor in a single unit often called an inertial measurement unit (IMU) or electronic stability control sensor.

Can I recalibrate the lateral accelerometer?

Some vehicles allow recalibration through a scan tool procedure. The vehicle must be on a level surface during calibration. If calibration fails, the sensor itself may need replacement.
