Combined Sensor Inspection

Switch the ignition to off.
Connect the M-MDS to the DLC-2.
Select the following PIDs and inspect the lateral acceleration and yaw rate. See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .
- 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.
