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 the ETS motor 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 RESUME swich signal is switching too frequently or stuck for too long, PCM sets P0567.
Item | Detecting Condition | Possible cause |
DTC Strategy | ● Monitors the switch is switching too frequently or stuck for too long. | ● Poor connection ● Faulty cruise switch ● Faulty PCM |
Enable Conditions | ● Engine is running ● Ignition voltage ≥ 9V ● Cruise control system type is learned | |
Threshold value | ● Input switch signal is switching too frequently or stuck | |
Diagnosis Time | ● Switching: more than 1 second failure for 300 seconds test ● Stuck: more than 75 seconds failure for 300 seconds test | |
MIL On Condition | ● NO MIL ON(DTC only) |
