2 CHECK LATERAL G SENSOR OUTPUT. 
  1. Park the vehicle on a level surface.
  2. Select {Current Data Display & Save} in Subaru Select Monitor.
  3. Read the lateral G sensor output displayed on screen.
 Is the indicated reading on the monitor display -1.5 - 1.5 m/s2 ? Go to step 3.  Replace the yaw rate & lateral G sensor.

  1. Turn the ignition switch to OFF.
  2. Remove the yaw rate & lateral G sensors from vehicle.
  3. Turn the ignition switch to ON, and select {Current Data Display & Save} in Subaru Select Monitor.
  4. Read the lateral G sensor output displayed on screen.
 When the yaw rate & lateral G sensor is inclined 90° to the right, is the indicated value 6.8 -12.8 m/s2 ? Go to step 4.  Replace the yaw rate & lateral G sensor.
4 CHECK LATERAL G SENSOR. 
Read the lateral G sensor output displayed on screen.		 When the yaw rate & lateral G sensor is inclined 90° to the left, is the indicated value -6.8 - -12.8 m/s2 ? Go to step 5.  Replace the yaw rate & lateral G sensor.
5 CHECK POOR CONTACT IN CONNECTORS. 
Turn the ignition switch to OFF.		 Is there poor contact in connector between VDCCM&H/U and yaw rate & lateral G sensor? Repair the connector. Go to step 6. 
6 CHECK THE VDCCM&H/U. 
  1. Connect all connectors.
  2. Erase the memory.
  3. Perform the Inspection Mode.
  4. Read the DTC.
