The cruise control system keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received. When the main switch is turned on with vehicle in the running mode, the battery voltage is applied to the ECM. When a signal from the control switch is input to the ECM while the vehicle is in state, the ECM controls fuel injection to make a car go at a steady speed you want. Also, while the system is operating, "CRUISE" indicator lamp in the meter assembly lights up.
If the switch signal's voltage is not within the calibrated ranges when ECM checks the switch signal under detecting condition, ECM sets P0564.
