Yaw Rate and G Sensor: Inspection

YAW RATE & LONGITUDINAL G AND LATERAL G SENSOR SIGNAL
1. CHECK YAW RATE & G SENSOR .
  1. Check the installing condition of the hydraulic unit assembly VSC (VDC).
  2. Using the Subaru Select Monitor, display the following items in the [Data monitor] of [Brake Control]. Ref. to COMMON (DIAGNOSTICS)>DATA MONITOR .
    - [Yaw Rate Sensor]
    - [Longitudinal G Sensor]
    - [Lateral G Sensor]
  3. Read the output of [Yaw Rate Sensor], [Longitudinal G Sensor] and [Lateral G Sensor].
    When the vehicle is placed horizontally, are the displayed values -1.5 - 1.5 m/s² for longitudinal G and lateral G sensor, and -4 - 4 deg/s for yaw rate sensor?
    
    Yes: Go to 2.
    
    No: Replace the hydraulic unit assembly VSC (VDC). Ref. to VEHICLE STABILITY CONTROL>VSC (VDC) CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VSCCM & H/U) .
2. PERFORM DRIVING TEST .
  Drive for approximately 10 minutes, and check that there is no system malfunction or the warning light illumination while driving.
  
  Is there any abnormal movement or the warning light illumination while driving?
  
  Yes: Perform the diagnosis according to DTCs for the VSC (VDC) system. Ref. to BRAKE CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .
  
  No: G sensor is normal.
