Code P0571 2015 Chevrolet Silverado Description
The P0571 diagnostic trouble code for a 2015 Chevrolet Silverado refers to an issue with the Cruise Control Brake Switch Circuit. The brake switch in question is responsible for disengaging the cruise control system when the brake pedal is applied. The vehicle's Powertrain Control Module (PCM) is responsible for controlling the cruise control system and receives input from the brake switch to determine whether it's safe to engage or disengage the system. If the PCM detects an irregularity in the brake switch signal, it will trigger the P0571 code.
