P056CCruise Control Cancel Signal

P056C indicates that the cruise control system has received a cancel signal, meaning the engine control module (ECM) or cruise control module detected an input that commanded the cruise control to disengage. The computer sets this code when it sees a cancel request from a switch, sensor, or related system without a corresponding fault in the cruise control engagement circuit.
