No. 5 Inspection of Vacuum Pump Assembly Drive Circuit





DESCRIPTION OF OPERATION
The input signal from the control switch causes transistor Tr1 to be ON. Accordingly, the cruise control relay is placed in the ON state to supply power to the vacuum pump assembly. The vacuum pump assembly consists of a diaphragm type negative pressure pump that is driven by a DC motor, and two solenoid valves (control valve and relief valve) and is controlled by the control unit as shown in the following table. When the brake pedal is depressed during cruise control operation, the power supply to the vacuum pump assembly is cut off.
