Code P0572 2015 Chevrolet Silverado Description

The Brake Pedal Position Sensor signal circuit is a B+ input from the Body Control Module (BCM) to the Engine Control Module (ECM). The BCM and ECM monitor the Brake Pedal Position Sensor signal circuit to detect when the brake pedal has been applied. When the brake pedal is applied, the BCM supplies B+ on the stop lamp signal circuit and also sends a serial data message to the ECM indicating that the brake pedal has been applied. This Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to ground or an open on the discrete brake signal circuit when the serial data message from the BCM indicates the brakes are applied. This diagnostic will run when the serial data message and the voltage signal on the brake switch signal circuit do not match for 8 out 10 times, and the condition is present for greater than 2 s.
