Subaru Legacy BN/BS (2015-2019) Service Manual / Vehicle dynamics control (vdc) / Vdc control module and hydraulic control unit (vdccm&h u) / 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 the bracket - hydraulic unit and the VDCCM&H/U.

(1) Install the VDCCM&H/U to the bracket - hydraulic unit.

Tightening torque:

Refer to “COMPONENT” of “General Description”. General Description > COMPONENT

2. Connect the ground terminal to battery sensor. NOTE

3. Bleed air from the brake system. Air Bleeding

4. Perform parameter confirmation, selection, and registration.

NOTE:
