Code C1473 Description

The C1473 diagnostic trouble code (DTC) indicates a Brake System Valves Calibration Data Failure. This means that there is a problem with the calibration data stored in the brake system valves, which are crucial components for the proper operation of the vehicle's braking system. The calibration data is essential for the valves to regulate the flow of brake fluid and ensure that the brakes function correctly. When this data fails, it can lead to improper braking performance, potentially compromising the safety of the vehicle.
