DTC P1572: Brake Pedal Switch Circuit

P1572 - BRAKE PEDAL SWITCH CIRCUIT

Description:  Indicates 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) control module and the ABS generates a driver brake application signal, which is then sent to the PCM.
Possible Causes: 
  • Incorrectly adjusted BPP switch or BPS
  • Blown fuse
  • Damaged BPP switch
  • Damaged BPS
  • BPP circuit open or short
  • BPS circuit open or short
Diagnostic Aids:  DTC P1572 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.
