Select the following PIDs, then inspect the lateral acceleration speed and the yaw rate.
- LAT_ACCL: (lateral acceleration speed)
- YAW_RATE: (yaw rate)
1. Lateral acceleration speed 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.
  Standard
  
  When the sensor is tilted to the right (A):
  
  LAT_ACCL changes negatively.
  
  When the sensor is tilted to the left (B):
  
  LAT_ACCL 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
  
  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.
