3.2TL TYPE S V6-3.2L SOHC (2002)
Hydraulic Control Assembly - Antilock Brakes: Testing and Inspection
Modulator Operation
Conventional brake mode
The brake fluid is provided to the brake calipers through four inlet valves. In ABS mode, the VSA control unit drives four inlet valves, four outlet
valves, ABS pump, and pump motor the same as conventional ABS.
VSA mode (pressure intensifying operation)
In pressure intensifying operation, the apply valve opens, the dump valve closes, and the pump motor operates. The cut off valve is closed by the
brake fluid for VSA control pressing on the pressure piston. At the same time, the brake fluid in the pressure chamber provides pressure to the brake
caliper.
VSA mode (pressure reducing operation)
