Select the following PIDs, then inspect the lateral acceleration speed and the yaw rate.
- LAT ACC: (lateral acceleration speed)
- YAW_RATE: (yaw rate)
1. Lateral acceleration speed inspection
  1. Verify the LAT ACC change when the combined sensor is tilted to the left and right.
    - If there is any malfunction, replace the combined sensor.
  Standard
  1. When the sensor is tilted to the right:
    1. LAT ACC changes negatively.
  2. When the sensor is tilted to the left:
    1. LAT ACC changes positively.
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.
  Standard
  1. When the sensor is rotated to the right:
    1. YAW_RATE changes negatively.
  2. When the sensor is rotated to the left:
    1. YAW_RATE changes positively.
