Hydraulic Control Unit

WARNING: This page is about a different car, the 2019 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.

Bleed air from the brake line, and perform No. 1) - 22) in section 2. Ref. to BRAKE>AIR BLEEDING>PROCEDURE>BRAKE LINE .
CAUTION:
- If there is a possibility that air enters the pressure control section in the hydraulic control unit, perform No. 11) - 16) in section 2.
- For normal air bleeding operation, do not operate the sequence control for the hydraulic control unit. (Operating the sequence control may let air in the normal air bleeding passages move to the pressure control section.)
- Be sure to perform the ABS sequence control mode first before the VDC sequence control mode.
NOTE: If there is a possibility that air enters the pressure control section in the hydraulic control unit, perform the sequence control mode for both of the ABS and VDC systems. (Refer to steps 14 to 16 for brake lining.)
