Is VDCCM&H/U installed properly without being tilted?

Is the bracket deformationfree?

Are the VDCCM&H/U installation bolts installed without missing or getting loose?

• Yes  : Go to  2.
• No  : Repair the defective part.
  • Install VDCCM&H/U properly.
  • Replace the bracket if faulty.
  • Tighten the VDCCM&H/U installation bolt. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>General Description>COMPONENT>VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM&H/U) .

    Go to 2.

1. Park the vehicle straight 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 [Steering Angle Sensor] indicated on the display screen.

Is the value of [Steering Angle Sensor] -10 - 10°?

• Yes  : Go to 3. 
• No  : Check the installation of steering angle sensor.

1. Park the vehicle straight 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 [Lateral G Sensor] and [Longitudinal G Sensor] indicated on the display screen.

Are the values of [Lateral G Sensor] and [Longitudinal G Sensor] -2 - 2 m/s² ?

• Yes  : Go to 4. 
• No  : Recheck from step 1, and if the problem is not solved, go to 7. Go to  7.

1. Using the Subaru Select Monitor, select Work Support.
2. Perform the VDC sensor midpoint setting mode. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>ADJUSTMENT>VDC SENSOR MIDPOINT SETTING MODE .

Is the 0 point setting successful?

• Yes  : Go to 5. 
• No  : Recheck from step 1, and when the 0 point setting is not possible, replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .

Drive approximately 10 minutes, and check if the warning lights illuminate or improperly operate during driving.

In a safe place, drive the vehicle while alternating acceleration and deceleration as much as possible.

Did the ABS warning light or VDC warning light remain off?

Does ABS or VDC operate without malfunction?

• Yes  : Go to 6. 
• No  : Recheck from step 1, and when the warning lights illuminate or improperly operate, replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .

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 [Lateral G Sensor] and [Longitudinal G Sensor] indicated on the display screen.

Are the values of [Lateral G Sensor] and [Longitudinal G Sensor] -1.5 - 1.5 m/s² ?

• Yes  : Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference.
• No  : Recheck from step 1, and if the problem is not solved, replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .

1. Remove the VDCCM&H/U installation bolt and bracket.
2. Keep VDCCM&H/U in a horizontal position.
3. Using the Subaru Select Monitor, select Data monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Subaru Select Monitor>OPERATION>DATA MONITOR .
4. Read [Lateral G Sensor] and [Longitudinal G Sensor] indicated on the display screen.

When the VDCCM & H/U is in a horizontal position, are the values of [Lateral G Sensor] and

[Longitudinal G Sensor] -1.5 - 1.5 m/s² ?

• Yes  : Check the bracket and brake pipe, and install VDCCM&H/U in a horizontal position to the vehicle.
• No  : Replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .
