Turn the ignition switch off.
Connect the M-MDS or equivalent to the DLC-2.

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: LAT_ACCL changes negatively.
    
    When the sensor is tilted to the left: 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: YAW_RATE changes negatively.
  
  When the sensor is rotated to the left: YAW_RATE changes positively.
