Select the following PIDs and inspect the lateral acceleration and yaw rate.
- LAT_ACCL (lateral acceleration)
- YAW_RATE (yaw rate)
  1. Lateral acceleration inspection
    1. Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.
      - If there is any malfunction, replace the combined sensor. (See COMBINED SENSOR REMOVAL/INSTALLATION .)
    Standard
    
    When the sensor is tilted to the right (A): LAT_ACCL changes positively.
    
    When the sensor is tilted to the left (B): LAT_ACCL changes negatively.

  2. Yaw rate inspection
    1. Verify the YAW_RATE change when the combined sensor is rotated to the left and right.
      - If there is any malfunction, replace the combined sensor. (See COMBINED SENSOR REMOVAL/INSTALLATION .)
    Standard
    
    When the sensor is rotated to the right (A): YAW_RATE changes negatively.
    
    When the sensor is rotated to the left (B): YAW_RATE changes positively.
