P1572 - Brake Pedal Switch Circuit

2007 Ford Focus SES, 4D Sedan, StandardSECTION 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 failed. One or both inputs to the powertrain control module (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 (DBA) signal, which is then sent to the PCM.
Possible Causes: 
  • Misadjusted brake switches, BPP or BPS
  • Blown fuse
  • Damaged BPP switch
  • Damaged BPS switch
  • Open or short in the BPP circuit
  • Open or short in the DBA circuit
  • Open or short in the BPS circuit
Diagnostic Aids:  DTC P1572 is set when the PCM does not sense the proper sequence of the brake pedal input signal from both the BPP and BPS switches when the brake pedal is pressed and released.
