SYSTEM OPERATION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)
35B-13
PRESSURE INCREASING MODE
When the ABS-ECU determines that none of the
wheels are approaching lock-up, it stops current sup-
ply to the solenoid valves. As a result, all the sole-
noid valves are de-energized, and the fluid in the
master cylinder flows through solenoid valve IN to
the wheel cylinders to apply greater pressure.
