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

[MacValeria]

If the car's automatic door lock keeps jumping, first check if the door is properly closed. Additionally, interference with the door sensor can also cause this phenomenon. Here is some extended information: 1. Function: The purpose of the automatic door lock is anti-theft. It quickly locks after driving to prevent door-pulling robberies during traffic jams or at red lights, providing a certain level of security. 2. Automatic door power grounding or brake light power line damage: Generally, after starting to drive, stepping on the first brake will automatically lock the doors to prevent passengers from accidentally opening the door and falling out. Many cars now have this design, especially family cars. When the car is stopped in P gear or turned off, the automatic door lock opens for easy exit. If the automatic door lock jumps randomly while driving, it indicates that the automatic door power is grounded or the brake light power line is damaged. It is recommended to visit a repair shop to troubleshoot the issue.
