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