Why does the car's automatic door lock keep jumping?

[LorenzoRose]

The reasons why the car's automatic door lock keeps jumping are: 1. The car door is not properly closed; 2. The car door touches the sensor. The purpose of the automatic door lock function is anti-theft. It can quickly lock after driving to prevent door pull robberies during traffic jams or at red lights, providing a certain level of security. Generally, after starting to drive, stepping on the brake for the first time will automatically lock the doors to prevent accidental opening and potential falls. Many cars now have this design, especially family cars. When the car stops in P gear or is turned off, the automatic door lock opens automatically for easy door access. If the automatic door lock jumps randomly while driving, it indicates that the automatic door power ground or the brake light power line is damaged. It is recommended to visit a repair shop to troubleshoot the issue.
