Solution
1. Preparation
  • Ensure the vehicle is on a level surface and securely parked.
  • Gather necessary tools and parts.
  • Disconnect the battery to prevent electrical shorts.
2. Scan and Clear Codes
  • Connect an OBD-II scanner to the vehicle's diagnostic port.
  • Record any fault codes related to the stability control system.
  • Clear the codes to see if they return after a test drive.
3. Inspect and Repair Wheel Speed Sensors
  • Remove the wheel on the affected side using a socket set.
  • Locate the ABS wheel speed sensor and visually inspect it for damage.
  • Clean the sensor and connector if dirty, or replace if damaged.
  • Reassemble the wheel and lower the vehicle.
4. Check Steering Angle Sensor
  • Access the steering angle sensor located on the steering column.
  • Use a diagnostic tool to verify calibration; if misaligned, recalibrate it according to manufacturer specifications.
  • If the sensor is faulty, replace it as per service manual instructions.
5. Brake Fluid Inspection
