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: |
|
|||
| 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. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
