MODELS WITH EyeSight

WHETHER A WHEEL TURNED FREELY OR NOT.
Check if the wheels have been turned freely for one minute or more, such as when the vehicle is jacked-up, under full-lock cornering or when the wheels are not in contact with road surface.

Did the wheels turn freely?
- Yes : VDC is normal. Clear the memory. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Clear memory .
- No : Go to 2.
CHECK OUTPUT OF LONGITUDINAL G SENSOR USING SUBARU SELECT MONITOR.
1. Park the vehicle on a level surface.
2. Using the Subaru Select Monitor, select Data monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Subaru Select Monitor>OPERATION>DATA MONITOR .
3. Read [Longitudinal G Sensor] indicated on the display screen.
Is the value of [Longitudinal G Sensor] -1.2 - 1.2 m/s² ?
- Yes : Go to 3.
- No : Replace the yaw rate & G sensor. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>Yaw Rate and G Sensor .
CHECK OUTPUT OF LONGITUDINAL G SENSOR USING SUBARU SELECT MONITOR.
1. Turn the ignition switch to OFF.
2. Remove the yaw rate & G sensor from vehicle. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>Yaw Rate and G Sensor .
3. Using the Subaru Select Monitor, select Data monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Subaru Select Monitor>OPERATION>DATA MONITOR .
4. Read [Longitudinal G Sensor] indicated on the display screen.
When the yaw rate & G sensor is inclined 90° to the front, is the value of [Longitudinal G Sensor] -6.8 - -12.8 m/s² ?
- Yes : Go to 4.
- No : Replace the yaw rate & G sensor. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>Yaw Rate and G Sensor .
CHECK OUTPUT OF LONGITUDINAL G SENSOR USING SUBARU SELECT MONITOR.
Read [Longitudinal G Sensor] indicated on the display screen.

When the yaw rate & G sensor is inclined 90° to the rear, is the value of [Longitudinal G Sensor] 6.8 - 12.8 m/s² ?
- Yes : Go to 5.
- No : Replace the yaw rate & G sensor. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>Yaw Rate and G Sensor .
CHECK POOR CONTACT OF CONNECTOR.
Turn the ignition switch to OFF.

Is there poor contact of connector between VDCCM&H/U and yaw rate & G sensor?
- Yes : Repair the connector.
- No : Go to 6.
CHECK VDCCM&H/U.
1. Connect all connectors.
2. Clear the memory. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Clear memory .
3. Perform the Inspection Mode. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Inspection Mode .
4. Read the DTC. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Read Diagnostic Trouble Code (DTC) .
Is the same DTC displayed?
- Yes : Replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .
- No : Go to 7.
CHECK DETECTION OF OTHER DTCS FOR VDC.
Ref. to BRAKE CONTROL (DIAGNOSTICS)>Read Diagnostic Trouble Code (DTC) .

Is any other DTC displayed?
- Yes : Perform the diagnosis according to DTC. Ref. to BRAKE CONTROL (DIAGNOSTICS)>List of Diagnostic Trouble Code (DTC) .
- No : Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference.
