View of the right side of control manifold (1) (1) Control manifold (2) Solenoid valve (3) Check valve (A) Outlet to brake oil coolers (B) Inlet from brake accumulator charging valve (C) Outlet to gear motor for the rear axle lubrication (D) Inlet from gear motor for the rear axle lubricationAfter the brake system demands are met, oil from the brake accumulator charging valve flows into control manifold (1) through inlet (B). Solenoid valve (2) controls the oil that is sent through outlet (C) to the gear motor for the rear axle lubrication. The Brake ECM controls the current that is sent solenoid valve (2). The current sent to solenoid valve (2) is based on the combination of feedback from the differential oil temperature sensor and other related information.After the oil goes through the gear motor for the rear axle lubrication, the oil is returned to the control manifold through inlet (D). The oil is then sent to the brake oil coolers and back into the brake system.
