(10) Switch group (truck body up) The hydraulic hoist system is electronically controlled through the Chassis Electronic Control Module (ECM). A gear pump that is mounted on the rear of the engine provides pressurized oil for the hoist system. A four position hoist control lever determines the operation of the dump body. The hoist control position sensor that is attached to the hoist control, sends signals to the chassis ECM. The position of the hoist control will energize the appropriate solenoid on the hoist control valve. The shifting of the solenoid will cause oil to be sent to the hoist cylinders in order to move the dump body. The signal from the position sensor is also used to neutralize the transmission.
