What does PDC failure mean?

[McBeau]

PDC stands for Parking Distance Control, which is the reverse radar detector. When PDC fails, it means the reverse radar is not functioning and cannot work properly. Here are the relevant details: 1. Introduction: The Parking Distance Control system, also known as the PDC control system, can detect obstacles in front of and behind the vehicle based on ultrasonic signals and issue audible, visual, or image alerts when necessary. 2. Fault detection: The Parking Distance Control module (PDC control module) has a fault diagnosis function, which can monitor ultrasonic sensors, the PDC switch, bus signals, and the module itself, and record related fault information. Fault information includes the nature of the fault, occurrence frequency, mileage, external temperature, etc. Typically, if a fault currently exists, both the audible alarm function and the visual alarm function will fail simultaneously.
