1. DTC P0568 description
The cruise control maintains the vehicle speed at a speed set by a driver. When the cruise control main switch is turned ON, a signal is sent to the ECM, and the cruise control indicator light in the instrument panel cluster illuminates. When the cruise control set switch is applied, a switch signal is sent to the ECM, and the vehicle speed is set or the vehicle speed decreases. If the ECM detects that the cruise control set switch signal repeats ON and OFF or stays ON, the DTC is set.
