This summary uses the existing diagnostic information shown in full below.
This means that the car's computer is not getting a signal from the brake pressure sensor. It's like when a light bulb is not working because it's not connected properly.
The C0573 code indicates that there is an issue with the brake pressure sensor circuit, specifically an open circuit or no connection.
The brake pressure sensor monitors the hydraulic pressure in the brake system. An open circuit means there is a break in the electrical path, preventing the sensor from sending data to the vehicle's control module.

The brake pressure sensor is typically located near the master cylinder or within the ABS module.
Q: Can I drive with the C0573 code?
A: It's not recommended to drive with this code active, as it may affect braking performance.
Q: How do I reset the ABS warning light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
