DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0504 | Brake Pedal Switch A / B Correlation | A DTC that sets when the PCM does not receive the correct sequence of signals from the CPP and BPP switches when the clutch is released and the brake pedal is pressed and released. |

| P0573 | Brake Pedal Switch A Circuit High | A DTC that sets when the PCM detects a short to voltage on the BPP switch signal. The PCM monitors the vehicle speed, engine speed, engine torque, and the BPP switch input during start and stop driving cycles. If the BPP switch input to the PCM is always on during start and stop driving cycles, this DTC is set in continuous memory. |
