Base Braking Mode
The baseline braking mode of the ABS modulator used in this vehicle is a diagonal split system. In this system, 1 master cylinder circuit supplies pressure to the right front and the left rear brakes. The other circuit supplies pressure to the left front and the right rear brakes. All valves in the hydraulic modulator are in their normal, non-energized positions as shown in the drawings found in the hydraulic diagram.
