Electronic Brake Control Module: Description and Operation
PURPOSE
The Electro-hydraulic Control Unit (EHCU), located inside the engine compartment on the left inner fender, regulates hydraulic pressure in the
brake system during an antilock stop.
OPERATION
The Brake Pressure Modulator Valve (BPMV) is split into 3 hydraulic channels right front, left front and rear brakes. Each channel has a isolation
valve and a dump valve. The front channels share a low pressure accumulator, attenuator and pump. The rear channel also has a low pressure
accumulator, attenuator and a pump. The rear brake channel of the BPMV controls both rear wheels simultaneously.
