P1572 - BRAKE PEDAL SWITCH CIRCUIT - DTC CHART

Description: This DTC sets when the brake input rationality test for brake pedal position (BPP) and brake pressure switch (BPS) has detected a concern. One or both inputs to the PCM did not change state when expected. On some vehicles with stability assist, the BPP switch is connected to the anti-lock brake system (ABS) module and the ABS generates a driver brake application signal, which is then sent to the PCM.
Possible Causes: Incorrectly adjusted BPP switch Blown fuse Damaged BPP switch Damaged BPS BPP circuit open BPP circuit short to voltage BPP circuit short to ground BPS circuit open BPS circuit short to voltage BPS circuit short to ground
Diagnostic Aids: This DTC sets when the PCM does not sense the correct sequence of the brake pedal input signal from both the BPP switch and the BPS when the brake pedal is pressed and released.
