DTC P0564 Cruise Control Multi-Function Input "A" Circuit: General Description

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 "AUTO CRUISE" 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 cruise control actuator is activated to operate the system.

Also, while the system is operating, "AUTO CRUISE" indicator lamp in the meter assembly lights up. In case of the cruise control system failure, the symptoms such as acceleration failure and vehicle speed setting failure will occur
