Combined Sensor Inspection

WARNING: This page is about a different car, the 2011 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

Turn the ignition switch off.
Connect the M-MDS 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.
