Removal and Installation

REMOVAL

1) Disconnect the ground cable from battery.
2) Remove the intake boot.

CAUTION:
Move aside the intake boot to perform the operation without disconnecting the PCV hose.

3) Remove the VDC control module & hydraulic control unit (VDCCM&H/U).
(1) Remove any dirt from around the VDCCM&H/U.
(2) Pull up the lock lever (b) while pressing the lock button (a) and disconnect the VDCCM&H/U connector.

CAUTION:
Do not pull on the harness when disconnecting the connector.





(3) Using a flare nut wrench, disconnect each brake pipe from VDCCM&H/U.

CAUTION:
- Wrap the brake pipe with a vinyl bag so as not to spill the brake fluid on the painted surface of the vehicle body.
- If brake fluid is spilled on the painted surface of the vehicle body, wash it off immediately with water and wipe clean.





(4) Remove the nuts and remove the VDCCM&H/U from the bracket - hydraulic unit.

CAUTION:
- Do not drop or bump the VDCCM&H/U.
- Do not turn the VDCCM&H/U upside down or place it sideways for storage.
- Be careful not to let foreign matter enter the VDCCM&H/U.
- Be careful that no water and fluid enter the connectors.





INSTALLATION

CAUTION:
- When installing the VDCCM&H/U to the bracket - hydraulic unit, make sure that there is no oil adhered to the bolts and the threads of VDCCM&H/U. If the oil is adhered, degrease it carefully before tightening.
- Connect the VDCCM&H/U connector securely.

1) Install each part in the reverse order of removal.

Tightening torque:
Refer to "COMPONENT" of "General Description".

2) Bleed air from the brake system.
3) Perform parameter confirmation, selection, and registration.

NOTE:
- When the VDCCM&H/U is replaced with a new part, be sure to perform the selection registration operation.
- Be sure to use the Subaru Select Monitor for the selection and registration of parameter.
- When the registration has not been performed, the DTC code "Parameter selection error" is detected together with the ABS/EBD/VDC warning light illumination.

(1) Check that the applied model and grade of the relevant vehicle are included.
(2) On {Confirm on parameter} display, enter the applied model of the relevant vehicle and check if it is correct. If the information is not correct, perform parameter selection and registration.
4) Perform mode setting for each sensor.
