What does it mean when the parking assist system stops working?

[HaydenLynn]

The reasons for the parking assist system stopping operation are as follows: 1. Damaged sensor or bumper: The sensor is blocked by components installed on the vehicle, such as the bumper cover. 2. Use of a temporary spare tire: The vehicle is used to transport loads exceeding its capacity. Below is relevant information: 1. Parking assist system: This includes ultrasonic sensors embedded in the front and rear bumpers, each with a diameter of about 15mm. The ultrasonic detection signals emitted by the sensors reflect when they encounter obstacles. Upon receiving the reflected signals, the sensors promptly feed them back to the system for distance calculation, alerting the driver through sound or video about the distance to obstacles outside the field of vision. 2. Fault symptoms: After receiving the vehicle, a test drive confirmed the fault. Upon turning on the ignition and starting the engine, shifting the transmission into R gear revealed that the red indicator light on the parking assist system (PTS) button lit up, and neither the front nor rear parking warning indicators responded, indicating that the parking assist system was in a disabled state.
